在PHP中拆分字符串的最快捷，最有效的方法

Question

I need to split string by just finding the first character. What is the quickest way to write it?

An example of string:

$string = 'Some text here| some text there--and here|another text here';

Expected result:

$new_string = 'Some text here';

This is a solution, I have. Is there a more efficient way to do it?

$explode = explode('|', $string);  
$new_string = explode[0];

Answer 1

Use strpos() and substr(). Strpos() will return as soon as the first occurrence is found, while explode() has to walk the whole string.
