Easiest work-around I've found for <5.3:<?php$string = "CamelCase"$string{0} = strtolower($string{0})echo $string; // outputs camelCase?>In some cases maybe more useful? $lower = strtolower( substr($upper,0,1) ) . substr($upper,1);A slight modification from Northie's post here ( http://us2.php.net/manual/en/function.ucfirst.php#68443), where lcfirst may not exist in your PHP build:<?phpif(false === function_exists('lcfirst')){ /** * Make a string's first character lowercase * * @param string $str * @return string the resulting string. */ function lcfirst( $str ) { $str[0] = strtolower($str[0]); return (string)$str; }}/* Tests */echo var_dump(lcFirst(NULL)).'<br />'; /* string(0) "" */echo var_dump(lcFirst('')) .'<br />'; /* string(0) "" */echo var_dump(lcFirst('S')) .'<br />'; /* string(1) "S" */echo var_dump(lcFirst('É')) .'<br />'; /* string(0) "�" */echo var_dump(lcFirst('Hello World!!!')); /* string(14) "hello World!!!" */
