HTTP being a text protocol, most, if not all, content that comes in
<link linkend="language.variables.globals">Superglobal arrays</link>,
like <varname>$_POST</varname> and <varname>$_GET</varname> will remain
as strings. PHP will not try to convert values to a specific type.
In the example below, <varname>$_GET["var1"]</varname> will contain the
string "null" and <varname>$_GET["var2"]</varname>, the string "123".
