Using substr

The second recommended approach is using the substr() function. Here is how to use it:

<‌?php

$str = 'hello';
$str = substr($str, 1);
var_dump($str); //=> 'ello'

?>

Using preg_replace

And the last handy function to use for removing the first character of a string is preg_replace():

<‌?php

$str = "hello";
$str = preg_replace('/^./', '', $str);
var_dump($str); //=> 'ello'

?>

Describing the ltrim Function

The ltrim() function is supported in PHP 4, PHP 5, and PHP 7. It returns a string with whitespace (or specified characters) stripped from the beginning.

Describing the substr Function

The substr() function is a built-in PHP function used for extracting a part of a string.

It is capable of returning the extracted part of a string if successful. On failure, it will return either false or an empty string.

Describing the preg_replace Function

The preg_replace() function can return a string or an array of strings. It replaces all matches of a pattern found in the input string with a replacement string.
