When comments have any " ' ", it'll break the javascript badly...
Ex: " // That isn't for something " -> This break the js!
Other than that, nice php :)
EDIT:
I fixed it!
Replace:
// Remove inline comment(s) [^1]
'#\s*\/\/.*$#m',
with:
// Remove inline comment(s) [^1]
'#((\/\*)[\S\s]*?(\*\/))|((\/\/)[\S\s]*?(?=[\n\r]))#',
Now it will accept even multiline comments.
Big thanks to http://regexr.com/ :p
EDIT2:
But it still doesn't accept code comments.
Like those: // mydiv.classList.add('fadeout');
It'll break.
@Fusseldieb the parser splits your comment code as string and comment like this:
array(
'// ',
'myDiv.classList.add(',
'\'fadeout\'',
');'
);Will try to fix this issue next time. Maybe by setting the comment string in a higher priority to be captured than the string string.
I have some issues with the js minifier.
'use strict' becomes 'usestrict'.
if('foo' in bar) becomes if('foo'inbar).
var Gesture becomes varGesture
var rule = typeof selector == 'object' ? selector : this.get(selector) becomes varrule=typeofselector=='object'?selector:this.get(selector)
I suppose there are more but can't detect them as the parser breaks on first issue.
Updated!
Added function arguments:
$output = minify_{$any}($input, $comment = 2, $quote = 2);- 0: Remove
- 1: Keep
- 2: Remove if/but/when … (example: keep if detected as IE conditional comments, keep if contains
@license, etc.)
<span>0</span>
will be "optimized" to
<span></span>
If I use an other number... all is correct
<span>1</span>
@MarlonGnauck Found the problem. PHP treat the string
0as booleanfalse. Weird.☹️
Great job! Congratulations!!!
It's good to have minify solutions in a single script or class.
It would be more interesting if you could adapt your code to a "Minify" class with public methods such as minify_html(), minify_css() and minify_js().
I tried many minifiers and all of them (including this one) fail with my scripts containing specific situations:
Case 1: single quote in a js comment:
number = Math.round(number - number % 1); // Plain Math.round doesn't just truncate
Case 2: two consecutive empty blocks of jquery (two "empty" files being minified):
$(function() {
});
$(function() {
});
Case 3: a comma after the last element of a JSON object:
var config= {
app_name : "Suporte On",
app_username : "suporte_on",
app_domain : "suporteon.com.br",
};
Thank you!

Yes, these functions are based on the
Minifyclass from a PHP CMS called Mecha.I tried many minifiers and all of them (including this one) fail with my scripts containing specific situations.
Trying to fix them. Do you have short examples that represent about before and after JavaScript output using this minifier?
FYI, I don’t have any plan to add ability to minify the variable name too. That‘s too overweight.
Hello. Thanks for the minifier. I have found a bug.
.text { background-position:0 -190px; }
transforms to:
.text{background-position:0 0 -190px}
@Saacy 👍
The JavaScript in the HTML and use of fn_minify_html () is not minimized. and comments in PHP is not minimized too.
Is it possible that this is supported? Thank you
See #gistcomment-1781082. PHP does not required to be minified because PHP files are not downloaded directly like normal files.
When minimizing javascript, the end } of a function and the next line are placed together. For example:
window.onload = function(e) {
externalLinks();
}
var phone_pattern = new RegExp("\\d{3}\\-\\d{3}\\-\\d{4}");
becomes
window.onload = function(e) {externalLinks();}var phone_pattern = new RegExp("\\d{3}\\-\\d{3}\\-\\d{4}");
which causes a javascript error.
EDIT: the below fixed the javascript error, but it broke the minimization. Not sure why?
To fix, I removed the part that removes white space(s) around { or } i.e. line 271 becomes:
'#\s*([!%&*\(\)\-=+\[\]|;:,.<>?\/])\s*#',
Thanks for a great script, it is a HUGE time saver for me attempting to do this from scratch.
FWIW, Google PageSpeed Insights still considers the javascript to be minimized with this change (which makes no sense, since it wasn't minimized).
@sodabob This minifier does not do any code validation. Your code is invalid because semicolon after object access is important (expected `;` and instead saw `(end)`). It is like when you put semicolon at the end of variable definition. This will fix the issue:
window.onload = function() {
}; // ← :)Explanation
window.onload = function() {
} // ← :(
function test() {
} // ← :)
window.onload = test // ← :(
window.onload = test; // ← :)
Hello.
Does the script concatenate multiple files? I couldn't find any info about that on the examples above.
Thanks.
@danielzilli No this script only works as a minifier. Concatenating requires extra function to do something like: get the content, minify, combine all of them and save the combined contents to a new file.
@tovic a ) symbol is missing at the end of the if in the line 257 (https://gist.github.com/tovic/d7b310dea3b33e4732c0#file-php-html-css-js-minifier-php-L257)
actually is:
if ($part[0] === '/' && (substr($part, -1) === '/' || preg_match('#\/[gimuy]*$#', $part)) {
should be:
if ($part[0] === '/' && (substr($part, -1) === '/' || preg_match('#\/[gimuy]*$#', $part))) {
@TriForceX Fixed thanks.
Hi, You have a wonderful script there...
Is it possible to include this php-html-css-js-minifier.php file in the header.php (For oscommerce stores) and get all CSS, JS, html compressed automatically on the fly?
`<?php
//header.php file
include 'includes/php-html-css-js-minifier.php';
//What code goes here to TRIGGER THE minify for all JS CSS FILES AND HTML on the fly.`
Please your help will be deeply appreciated;
Warm Regds.
@radhava Please check #gistcomment-2063222
To make such functionality requires a lot of work. And sometimes by making everything automatic will also lead to uncontrollable results.
Hello, your function minify_css dont work with bootstrap medias querys, can you help me to fix them?
I try to minify this https://scotch.io/tutorials/default-sizes-for-twitter-bootstraps-media-queries
The file css show is empty.
Thanks.

@ivobarbosa Haven’t checked yet, but will add this to my TODO list.
It's a great tool, but has weird bug:
{% for lang_abbr, lang_name in langs %} <li> <a class="flag flag-{{ lang_abbr }}" title="{{ lang_name }}" href="{{ sites[lang_abbr] ~ uri }}"> {{ lang_name }} </a> </li> {% endfor %}
But this fork saved me : https://gist.github.com/Rodrigo54/93169db48194d470188f
Thx for your work.
I've had a problem with the CSS Minifier:
// Replace zero unit(s) with0[^5] '#\b(?:0\.)?0([a-z]+\b|%)#i',
Matches e.g. '2.0vmax' and changed it to "2.0" because "\b" matches "." and '(?:0.)?' is not required.
Here is my poor "update" of your Pattern, maybe someone can do it in elegant:
Search:
'#(\s|:|,\()(?:0\.0|0)(?:[a-z]+\b|%)|(?:0\.0)#i',
Replace with:
'${1}0',
By the way I added a replace for "0.0" (zero float without a unit).
Best regards
Edit:
Changed the pattern to ''#(\s|:|,()(?:0.0|0)(?:[a-z]+\b|%)|(?:0.0[^0-9])#i',' because not only '0.0' was changed to '0'. Also '0.07em' was changed to '07em'... Maybe someone would write a clean pattern? ;)
@moonston3 I am still playing around with this regex → https://regex101.com/r/odUcvs/1
The last update introduced a bug that I have experienced in JS minification.
It removes this / ( forward slash ) character within js regex. But the previous js minify definition with define('MINIFY_PATTERN_JS', '\b/[^\n]+?/[gimuy]*\b'); works fine.
thanks.
This really breaks on regex in javascript minification. Or, better yet, it deletes literally anything that starts with a forward slash. "/".
For now, something like this is too complicated for me to fix, unfortunately :(
@rinku17 @BabyDead Thanks for the report. The last update should fix the issue. My mistake, sorry.
Found the regex, unfortunately not reverse-able with JavaScript:
javascript code var txt="am"; converted to var txt=am; without ";
also, you can use 0 and 1 for replace false and true (or !1 and !0 - I saw this in some minified files);
also, you can use 0 and 1 for replace false and true (or !1 and !0 - I saw this in some minified files);
Nice script. I noticed that MINIFY_HTML removes domain name to make the paths relative - that's problematic in some instances, for example, all of your og:image tags will show relative paths, which will break when someone posts your URL to social media.
hi, i found two css issues:
- it changes the unicode-range at the @font-face, this font wont be visible eg
unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD;
to
unicode-range:U+0000-0,U+0131,U+0152-0153,U+02BB-02BC,U+02C6,U+02DA,U+02DC,U+2000-206F,U+2074,U+20AC,U+2122,U+2191,U+2193,U+2212,U+2215,U+FEFF,U+FFFD
the related part in your code:
// Replace zero unit(s) with0 [^5] '#\b(?<!\d\.)(?:0+\.)?0+(?:[a-z]+\b)#i',
- if you use an svg as a background-image, it removes the quote, but it needs it

the related part in your code:

Thanks for the reports! Will update this next time.
Hello @tovic,
This is Works Great Only one Thing I have notice that is in all the place where URL is write with external or internal link in the code that is Converted to /"
Like example .
Original Html : <link href="https://bootstrap/bootstrap.min.css" rel="stylesheet">
Converted Minify HTML : <link href=/"https://bootstrap/bootstrap.min.css/" rel=/"stylesheet/">
And I have see the code where Find the Comment you have writed
// Minify URL(s)
In that you have coded str_replace the " with /" and ' with /' can I known what is the purpose behind that to do.
Thanks,
@dipesh711 There must be some errors in the
$urlvalue. Please check by dumping it likevar_dump($url). What do you see?
In that you have coded str_replace the " with /" and ' with /' can I know what is the purpose behind that to do (?)
Yes. The code said: str_replace the
http://example.com"with/"andhttp://example.com'with/'
Maybe gist should be rewritten to a library with a git repo instead of just a gist?
@pwFoo Yes, it IS a library, but it depends to the Mecha CMS core.
If an if/else statement is used without curly brackets, an extra line feed appears.
for example:
if (a1 == "1")
E ="err1";
else
E ="err2";
Will become:
if(a1=="1")E="err1";else
E="err2";
Thanks
Thanks. :)
I had to change
define('MINIFY_PATTERN_JS', '/[^\n]+?/[gimuy]*');
to
define('MINIFY_PATTERN_JS', '/[^\n|(\\/)]+?/[gimuy]*');
to avoid issues with regexpresions that had internal escaped /
like this was failing.

I have an issue with this minifier.
I'm going to improve my SEO. This is the reason why I convert all image src with path in image base64 string.
When I parse my HTML with minifier it crash and the response page is empty.
Do you have any suggestion?
