Replace last occurrence of a string in a string
You can use this function:
function str_lreplace($search, $replace, $subject){ $pos = strrpos($subject, $search); if($pos !== false) { $subject = substr_replace($subject, $replace, $pos, strlen($search)); } return $subject;}
Another 1-liner but without preg:
$subject = 'bourbon, scotch, beer';$search = ',';$replace = ', and';echo strrev(implode(strrev($replace), explode(strrev($search), strrev($subject), 2))); //output: bourbon, scotch, and beer
$string = 'this is my world, not my world';$find = 'world';$replace = 'farm';$result = preg_replace(strrev("/$find/"),strrev($replace),strrev($string),1);echo strrev($result); //output: this is my world, not my farm
