Easiest work-around I've found for <5.3:
<?php
$string = "CamelCase"
$string{0} = strtolower($string{0})
echo $string; // outputs camelCase
?>
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
lcfirst — Make a string's first character lowercase
Returns a string with the first character of
string
lowercased if that character is
an ASCII character in the range "A"
(0x41) to
"Z"
(0x5a).
string
The input string.
Returns the resulting string.
Version | Description |
---|---|
8.2.0 | Case conversion no longer depends on the locale set with setlocale(). Only ASCII characters will be converted. |
Example #1 lcfirst() example
<?php
$foo = 'HelloWorld';
$foo = lcfirst($foo); // helloWorld
$bar = 'HELLO WORLD!';
$bar = lcfirst($bar); // hELLO WORLD!
$bar = lcfirst(strtoupper($bar)); // hELLO WORLD!
?>

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:
<?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!!!" */
