Question

I am new to php and I have no idea how to extract the exact things I want in a string.
for example:

Instant Oats Drink - Chocolate Flavour 165g (33g x 5)

I want to extract this data so that

Name: Instant Oats Drink - Chocolate Flavour
Weight: 165g
number of pack: 5
unit weight: 33g

Please give me some help on this question.

Answer 1

If all of your strings have that same form you can use regular expressions.

consider that :

<?php

    $str = "Instant Oats Drink - Chocolate Flavour 165g (33g x 5)";

    preg_match('/(?P<title>[a-zA-Z\s\-]*)(?P<grammars>[0-9]*g)(\s+\()(?P<portion>[0-9]+g)(\s+x\s+)(?P<times>[0-9]+)(\))/', $str, $m);

    echo "Title : " . $m['title'] . '<br />';
    echo "Grammars : " . $m['grammars'] . '<br />';
    echo "Portion : " . $m['portion'] . '<br />';
    echo "Times : " . $m['times'] . '<br />';

?>

Based on @Troy answer you can even use that one that is even sorten

<?php

    $str = "Instant Oats Drink - Chocolate Flavour 165g (33g x 5)";

    preg_match('/(?P<title>.*) (?P<grammars>\d+g) \((?P<portion>\d+g) x (?P<times>\d+)\)/', $str, $m);

    echo "Title : " . $m['title'] . '<br />';
    echo "Grammars : " . $m['grammars'] . '<br />';
    echo "Portion : " . $m['portion'] . '<br />';
    echo "Times : " . $m['times'] . '<br />';
