我们如何在php中选择一个特定字符的字符串？ 注意：不使用explode（）

Question

How we can select a string up to specific character in php?

ie I have a string Wednesday 16-January-2013. I need to get only up to first space.

ie output should be Wednesday.

I done it using explode,

<?php
explode(" ",Wednesday 16-January-2013)
?>

But too many explodes and array are permitted in the code. So,

How I can do it without using explode()?

Answer 1

As of PHP 5.3.0 you can use strstr function to return the part of the haystack before the first occurrence of the needle (excluding the needle):

$dayOfWeek = strstr('Wednesday 16-January-2013', ' ', true);
echo $dayOfWeek; // prints Wednesday
