删除每行中一个字符后的所有内容并返回剩下的内容

Question

So let's say I have the following text:

This is line number 1. This is my line number 2. This is his line number 3. This is her line number 4. This is their line number 5.

I want to remove the word number and everything following it and return what's left (on separate lines, of course).

I hope this is possible and I didn't over-complicate the question, thanks!

Answer 1

strstr() is made for you, together with explode

$string = 'This is line number 1.
This is my line number 2.
This is his line number 3.
This is her line number 4.
This is their line number 5.';

$ex = explode('.',$string);
var_dump($ex);

foreach ($ex as $x) {
    echo strstr($x, 'number',true)."<br>";
}
