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:
<?php
if(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!!!" */
