Deleting after a given character

[etrader]

I want to delete everything after a given character; e.g. wanna get the first word from this string by deleting everything after first occurrence of "-"

$str="word1-word2-word3";

I use this trick to do so

$str2=substr($str,0,strpos($str, '-'));

 

This works perfectly, but the problem is when the string is just one word without the given character (i.e. "-"). It will return nothing for $str="word1";

Not sure if you need the rest of the items also in that string but if you do you could use explode

 

$str="word1-word2-word3"; 
$items = explode($str, '-'); // wil create array of 3 items (word1, word2 and word3)

brilliant idea, $str2[0] will always return regardless of the existence of the given character. But I am still open to new ideas

Don't know if you have further needs or more complicated strings, but according to your description this would work

 

$str1 = 'word1-word2-word3';
$str2 = 'word1';

function myChop($str)
{
if ($result = substr($str, 0, strpos($str, '-')))
return $result;
else
return $str;
}

var_dump(myChop($str1));
var_dump(myChop($str2));

Thanks TeNDoLLA, I prefer the explode trick. It's quite simple, and I am dealing with explode a lot.
