使用正则表达式获取字符串

Question

These are examples of my strings:

My title - K21
Some title  - G-21
Title something - M-02

I need to strip the code and the hyphen so I get clear title.

My title
Some title
Title something

This is the code I came up so far, but it gives me G-21 as result, and I need the opposite, I need a result of regular expression.

$string = 'Some title - G-21';
$pattern = '/.+? (?=–)/i'; // this is ok, &#8211 is for '-'
echo preg_replace($pattern, '', $string);

Answer 1

Do you have to use a regular expressions?

<?php
$str = 'Some title  - G-21';
$res = trim(array_shift(explode("&#8211;", $str, 2)));

echo $res;
?>
