arrays - PHP Transformation string -

let's have array structure

$array = array(array('a' => 'a', 'x' => $something));

the variable $something can that: 1-3 or 1,3 or 1-3, 2-5. transform variable $array in:

case 1. $something = 1-3

$array = array(array('a' => 'a', 'x' => array(1,2,3)));

case 2. $something = 1,3

$array = array(array('a' => 'a', 'x' => array(1,3)));

case 3.. $something = 1-3, 2-5

$array = array(array('a' => 'a', 'x' => array(1,2,3,4,5)));

i tried utilize preg_match doesn't work. can give me hint utilize else?

you looking explode split input string, range generate array contents , array_merge merge result.

something works:

<?php $something = '1-3, 2-5'; $array = array(array('a' => 'a', 'x' => array())); $result = array(); foreach (explode(', ', $something) $input) { $rangeparts = explode('-', $input); $result = array_merge($result, range($rangeparts[0], $rangeparts[1])); } // contains duplicate entries because 1-3 , 2-5 overlap - utilize array_unique remove duplicates or alter input $array[0]['x'] = $result;

in lastly assignment can either wrap $result in array_unique 1:1 match illustration or edit input ($something) reflect inclusive/exclusive-rules of range function.
