In response to LaKing at D250 dot hu, this is incredible bad practice.
You should obviously never spam str_replace when you could instead do it like this:
$array1[]="%C3%8D";
$array1[]="%C3%AD";
$array2[]="%CD";
$array2[]=%ED";
$string=str_replace($array1, $array2, $string);
By the way, here is a function i wrote, (more on my blog):
if (!function_exists("filesystemcode")){
function filesystemcode($string, $arr1="a", $arr2="b") {
$c=array();
if (isset($arr1)) {
if (!isset(${$arr1}) || !is_array(${$arr1})){
${$arr1} = array('%21', '%2A', '%27', '%28',
'%29', '%3B', '%3A', '%40', '%26',
'%3D', '%2B', '%24', '%2C', '%2F',
'%3F', '%25', '%23', '%5B', '%5D');
}}
if (isset($arr2)) {
if (!isset(${$arr2}) || !is_array(${$arr2})){
${$arr2} = array('!', '*', "'", "(", ")",
";", ":", "@", "&", "=", "+",
"$", ",", "/", "?", "%", "#",
"[", "]");}else{$b='';}
}
if (isset($a) && isset($b)){
return str_replace($a, $b, $string);
}else{return($string);}
}
}
Remove html compatible encoded illegal filename characters:
//$string="%21dad";
$string=filesystemcode($string, "a", "c");
//echo $string; //"dad";
Remove illegal filename chars:
//$string="/dad";
$string=filesystemcode($string, "b", "c");
//echo $string; //"dad";
Convert filesystem incompatible chars into html compatible chars:
//$string="!dad";
$string=filesystemcode($string, "b", "a");
//echo $string; //"%21dad";
Convert html compatible chars into filesystem incompatible chars:
//$string="%21dad";
$string=filesystemcode($string, "a", "b");
//echo $string; //"!dad";
