I needed a function in PHP to do the same job as the complete escape function in Javascript. It took me some time not to find it. But findaly I decided to write my own code. So just to save time:
<?php
function fullescape($in)
{
$out = '';
for ($i=0;$i<strlen($in);$i++)
{
$hex = dechex(ord($in[$i]));
if ($hex=='')
$out = $out.urlencode($in[$i]);
else
$out = $out .'%'.((strlen($hex)==1) ? ('0'.strtoupper($hex)):(strtoupper($hex)));
}
$out = str_replace('+','%20',$out);
$out = str_replace('_','%5F',$out);
$out = str_replace('.','%2E',$out);
$out = str_replace('-','%2D',$out);
return $out;
}
?>
It can be fully decoded using the unscape function in Javascript.
