Sometimes we need replace just first occurrence , a small function that can help you.
<?php
$string = 'alpharomero alpha arlekino';
var_dump(str_replace_once('alpha','[replaced]', $string));
var_dump($string);
echo '<hr>';
var_dump(str_replace_once('a','[replaced]', $string));
var_dump($string);
echo '<hr>';
var_dump(str_replace_once('abnormal','[replaced]', $string));
var_dump($string);
echo '<hr>';
var_dump(str_replace_once('n','[replaced]', $string));
var_dump($string);
echo '<hr>';
function str_replace_once($str_pattern, $str_replacement, $string){
if (strpos($string, $str_pattern) !== false){
$occurrence = strpos($string, $str_pattern);
return substr_replace($string, $str_replacement, strpos($string, $str_pattern),
strlen($str_pattern));
}
return $string;
}
?>
