Parses <parameter>str</parameter> as if it were the query string
|
|
passed via a URL and sets variables in the current scope. If
|
|
the second parameter <parameter>arr</parameter> is present,
|
|
variables are stored in this variable as array elements instead.

Support for the optional second parameter was added in PHP 4.0.3.

To get the current <emphasis>QUERY_STRING</emphasis>, you may use the variable
|
|
<link linkend="reserved.variables.server">$_SERVER['QUERY_STRING']</link>.
|
|
Also, you may want to read the section on
|
|
<link linkend="language.variables.external">variables from outside of PHP</link>.

The <link linkend="ini.magic-quotes-gpc">magic_quotes_gpc</link> setting
|
|
affects the output of this function, as <function>parse_str</function> uses
|
|
the same mechanism that PHP uses to populate the <literal>$_GET</literal>,
|
|
<literal>$_POST</literal>, etc. variables.
