Explode String in PHP

Question

If I have a string "123x456x78", how could I explode it to return an array containing "123" as the first element and "456" as the second element? Basically, I want to take strings that are followed by "x" (which is why "78" should be thrown out). I've been messing around with regular expressions, but am having trouble.

Thanks!

EDIT: if the string were "123x456x78x" I would need three elements: "123", "456", "78". Basically, for each region following an "x", I need to record the string up until the next "x".

Answer 1

Loads of different ways, but here's a RegEx as you were trying that:

$str = "123x456x78";
preg_match_all("/(\d+)x/", $str, $matches);
var_dump($matches[1]);

Output:

array(2) { [0]=> string(3) "123" [1]=> string(3) "456" }

Answer 2

$arr = explode("x", "123x456x78");

and then

unset($arr[2]);

if you really can't stand that poor 78.

Answer 3

use explode

$string='123x456x78';

$res = explode('x', $string);
if(count($res) > 0) {
    echo $res[0];
    if(count($res) > 1) {
        echo $res[1];
    }
}

Answer 4

$var = "123x456x78";
$array = explode("x", $var);
array_pop($array);

Answer 5

To explode AND remove the last result:

$string='123x456x78'; // original string

$res = explode('x', $string); // resulting array, exploded by 'x'

$c = count($res) - 1; // last key #, since array starts at 0 subtract 1

unset($res[$c]); // unset that last value, leaving you with everything else but that.

Answer 6

While I'm all for regular expressions, in this case it might be easier to just use PHP's array functions...

$result=array_slice(explode('x',$yourstring),0,-1);

This should work because only the last element returned by explode won't be followed by an 'x'. Not sure if explode will add an empty string as the last element if it ends on 'x' though, you might have to test that...

Answer 7

Use this below code to explode. It works well!

   <?php
    $str='123x456x78';
    $res=explode('x',$str);
    unset($res[count($res)-1]); // remove last array element
    print_r($res);
    ?>
