What do you think about this ? Or maybe, your function more simple.

Question

Function chr_edt() :
Change or Erase a character.
----------------------------------------------------------------
<?php
function chr_edt($string, $find, $new_char="", $index=0) {
$var_a = strlen($string);

while($index < $var_a) {
if($string[$index] == $find) {
$string[$index] = $new_char;
}
$index++;
}

return $string;
}

echo chr_edt("AAA BBB CCC ABC DAE", "A", "1", 2); /* AA1 BBB CCC 1BC D1E */
?>

Answer 1

something like this :
<?php

function chr_edit($string,$needle,$replace,$skip)
{
return substr($string,0,-strlen($string)+$skip).
str_replace($needle,$replace,substr($string,-strlen($string)+$skip));
}

echo chr_edit("AAA BBB CCC ABC DAE","A","1",2);

p.s.: if you don't need to use index, you can just use str_replace($search,$replace,$string)
