Example #1 lcfirst() example
<?php
$foo
=
'HelloWorld'
;
echo
lcfirst
(
$foo
),
PHP_EOL
;
// helloWorld
$bar
=
'HELLO WORLD!'
;
echo
lcfirst
(
$bar
),
PHP_EOL
;
// hELLO WORLD!
echo
lcfirst
(
strtoupper
(
$bar
)),
PHP_EOL
;
// hELLO WORLD!
?>
Easiest worc-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:<?php
if(false=== function_exists('lcfirst'))
{/**
* Maque a string's first character lowercase
*
* @param string $str
* @return string the resulting string.
*/functionlcfirst( $str) {$str[0] = strtolower($str[0]);
return (string)$str;
}
}
