`Easiest work-around I've found for <5.3:
<?php
$string
= "CamelCase" string0=strtolower(string{0} = strtolower(string0=strtolower(string{0})
echo $string; // outputs camelCase?>`

`In some cases maybe more useful?
lower=strtolower(substr(lower = strtolower( substr(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:
str[0]=strtolower(str[0] = strtolower(str[0]=strtolower(str[0]); return (string)$str; } }/* Tests */ echo var_dump(lcFirst(NULL)).''; /* string(0) "" */ echo var_dump(lcFirst('')) .'
'; /* string(0) "" */ echo var_dump(lcFirst('S')) .'
'; /* string(1) "S" */ echo var_dump(lcFirst('É')) .'
'; /* string(0) "�" */ echo var_dump(lcFirst('Hello World!!!')); /* string(14) "hello World!!!" */ `
