| * If the value of the $tags[$tagname] entry is an array, advanced processing of the tags is initialized. These are the options: | |
| * | |
| * $tags[$tagname] = Array( | |
| * 'overrideAttribs' => '' If set, this string is preset as the attributes of the tag | |
| * 'allowedAttribs' => '0' (zero) = no attributes allowed, '[commalist of attributes]' = only allowed attributes. If blank, all attributes are allowed. | |
| * 'fixAttrib' => Array( | |
| * '[attribute name]' => Array ( | |
| * 'set' => Force the attribute value to this value. | |
| * 'unset' => Boolean: If set, the attribute is unset. | |
| * 'default' => If no attribute exists by this name, this value is set as default value (if this value is not blank) | |
| * 'always' => Boolean. If set, the attribute is always processed. Normally an attribute is processed only if it exists | |
| * 'trim,intval,lower,upper' => All booleans. If any of these keys are set, the value is passed through the respective PHP-functions. | |
| * 'range' => Array ('[low limit]','[high limit, optional]') Setting integer range. | |
| * 'list' => Array ('[value1/default]','[value2]','[value3]') Attribute must be in this list. If not, the value is set to the first element. | |
| * 'removeIfFalse' => Boolean/'blank'. If set, then the attribute is removed if it is 'FALSE'. If this value is set to 'blank' then the value must be a blank string (that means a 'zero' value will not be removed) | |
| * 'removeIfEquals' => [value] If the attribute value matches the value set here, then it is removed. | |
| * 'casesensitiveComp' => 1 If set, then the removeIfEquals and list comparisons will be case sensitive. Otherwise not. | |
| * ) | |
| * ), | |
| * 'protect' => '', Boolean. If set, the tag <> is converted to < and > | |
| * 'remap' => '', String. If set, the tagname is remapped to this tagname | |
| * 'rmTagIfNoAttrib' => '', Boolean. If set, then the tag is removed if no attributes happend to be there. | |
| * 'nesting' => '', Boolean/'global'. If set TRUE, then this tag must have starting and ending tags in the correct order. Any tags not in this order will be discarded. Thus '</B><B><I></B></I></B>' will be converted to '<B><I></B></I>'. Is the value 'global' then true nesting in relation to other tags marked for 'global' nesting control is preserved. This means that if <B> and <I> are set for global nesting then this string '</B><B><I></B></I></B>' is converted to '<B></B>' | |

| * @param array $tags Is an array where each key is a tagname in lowercase. Only tags present as keys in this array are preserved. The value of the key can be an array with a vast number of options to configure. | |
| * @param string $keepAll Boolean/'protect', if set, then all tags are kept regardless of tags present as keys in $tags-array. If 'protect' then the preserved tags have their <> converted to < and > | |
| * @param int $hSC Values -1,0,1,2: Set to zero= disabled, set to 1 then the content BETWEEN tags is htmlspecialchar()'ed, set to -1 its the opposite and set to 2 the content will be HSC'ed BUT with preservation for real entities (eg. "&" or "ê") | |
