如何找到单词并删除后的单词？

Question

$string = 'hello world php is a bla bla..';

How to keep 'hello world php', by finding if the string contains any 'is', and then remove all the characters after it?

I can't use substr because the occurrence of 'is' is not consistent, also it may be repeatable. How to catch the first one?

Answer 1

You can use explode:

<?php

$string = 'hello world php is a bla bla..';

$string = explode(' is ', $string);

echo $string[0];

?>
