how to take part of a string using explode()

Question

i have sample data like this :

i want to get integer in the red box. i now i can using explode(). but I am confused to apply in my problem. how can i apply explode to my problem?

this my code :

$ikan=$_POST['ikan']; //example : Katombo,(30 basket)
$kata=explode("(", $ikan);

Answer 1

We use explode two times after we explode the first array.

CODE

$ikan= 'Katombo,(30 basket)';
$kata= explode(" ", explode("(", $ikan)[1])[0];
echo $kata;

OUTPUT

30

UPDATED ANSWER If you want to loop it and use regex. you can use the ff:

$ikan= array('Katombo,(30 basket)', 'Layang,(0 basket)', 'Loka-loka, (0 basket)', 'Tongkol, (0 basket)');
$kata = array();
foreach($ikan as $value){
     $kata[] = explode(" ", explode("(", $value)[1])[0];
}

Using preg_match_all and regex

$ikan= array('Katombo,(30 basket)', 'Layang,(0 basket)', 'Loka-loka, (0 basket)', 'Tongkol, (0 basket)');
$kata = array();
foreach($ikan as $value){
    preg_match_all("/(\d+)/", $value,$num);
    $kata[] = $num[0][0];
}
