A faster way to replace the strings in multidimensional array is to json_encode() it, do the str_replace() and then json_decode() it, like this:
<?php
function str_replace_json($search, $replace, $subject){
return json_decode(str_replace($search, $replace, json_encode($subject)));
}
?>
This method is almost 3x faster (in 10000 runs.) than using recursive calling and looping method, and 10x simpler in coding.
Compared to:
<?php
function str_replace_deep($search, $replace, $subject)
{
if (is_array($subject))
{
foreach($subject as &$oneSubject)
$oneSubject = str_replace_deep($search, $replace, $oneSubject);
unset($oneSubject);
return $subject;
} else {
return str_replace($search, $replace, $subject);
}
}
?>
