|
|
This function is identical to
|
|
<function>htmlspecialchars</function> in all ways, except that
|
|
all characters which have HTML character entity equivalents are
|
|
translated into these entities. Like
|
|
<function>htmlspecialchars</function>, it takes an optional
|
|
second argument which indicates what should be done with single
|
|
and double quotes. <constant>ENT_COMPAT</constant> (the default)
|
|
will only convert double-quotes and leave single-quotes alone.
|
|
<constant>ENT_QUOTES</constant> will convert both double and
|
|
single quotes, and <constant>ENT_NOQUOTES</constant> will leave
|
|
both double and single quotes unconverted.
|
|
</para>
|
|
<para>
|
|
At present, the ISO-8859-1 character set is used as default.
|
|
Support for the optional second argument was added in PHP 3.0.17 and PHP
|
|
4.0.3.
|
|
</para>
|
|
<para>
|
|
Like <function>htmlspecialchars</function>, it takes an optional
|
|
third argument which defines character set used in conversion.
|
|
Support for this argument was added in PHP 4.1.0.

There is no reverse of this function. However, you can create one on your
|
|
own. Here is an example of how to do this.
