substr in PHP is a built-in function used to extract a part of the given string. The function returns the substring specified by the start and length parameter. It is supported by PHP 4 and above. Let us see how we can use substr() to cut a portion of the string.
From the PHP documentation: Characters within strings may be accessed and modified by specifying the zero-based offset of the desired character after the string using square array brackets, as in $str[42] . Think of a string as an array of characters for this purpose.
You can use the PHP strpos() function to check whether a string contains a specific word or not. The strpos() function returns the position of the first occurrence of a substring in a string. If the substring is not found it returns false .
Try this:
$username = substr($username, 0, strpos($username, '@'));
