// Using Single Quotes



echo 'This is a simple string<br/>';

echo 'You can also have embedded newlines in 
strings this way as PHP ignores white space <br/>';

// Outputs: Arnold once said: "I'll be back"
echo 'Arnold once said: "I\'ll be back"<br/>';

// Outputs: This will not expand: \n a newline
echo 'This will not expand: \n to a newline <br/>';

// Outputs: Variables do not $expand $either
echo 'Variables do not $expand $either<br/><br/><br/><br/>';




// Using Double Quotes




echo "This is a simple string<br/>";

echo "You can also have embedded newlines in 
strings this way as PHP ignores white space <br/>";

// Outputs: Arnold once said: "I'll be back"
// echo "Arnold once said: "I\'ll be back"<br/><br/>";





// Variables Inside Quotes





// I have been doing this ...

$a = 1;
$b = 3;

echo 'a='. $a . ' and b= ' . $b . '<br/>';

// But with double quotes, you can do this

echo "a=$a and b=$b <br/>";

// or this ...

$juice = "apple";
$great = 'fantastic';

echo "He drank some $juice juice.<br/>";   // He drank some apple juice
echo "This is {$great}<br/>";      // This is fantastic

$juices = array("apple", "orange", "koolaid1" => "purple");

echo "He drank some $juices[1] juice.<br/>";
echo "He drank some $juices[koolaid1] juice.<br/>";
echo "He drank some {$juices[0]} juice.<br/><br/>";

// All because I am using double quotes




// String Operators



// Concatenate
echo $a = "Hello";
echo '<br/>';
echo $b = $a . "World!"; // now $b contains "Hello World!"
echo '<br/><br/>';


// Append
echo $a = "Hello";   echo '<br/>';
echo $a .= "World!";     // now $a contains "Hello World!"



// Explode



// Example 1

$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";

$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo '<br/>';
echo $pieces[1]; // piece2
echo '<br/><br/>';

// Example 2

$data = "foo:*:1023:1000::/home/foo:/bin/sh";
list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);
echo $user; // foo
echo '<br/>';
echo $pass; // *


// Using explode with the API
