Filter a string and store in array

Question

I have a one string.

$a = '[{"size":"6Y","quantity":15}]';

I want to store 6Y and 15 in array. Please help me.

Answer 1

Use json_decode()

You have a json encoded string.

And need to decode it and assign size and quantity to an array.

Working example:

<?php
$a = '[{"size":"6Y","quantity":15}]';
$b = json_decode($a, TRUE);
$c = array();
if (! empty($b[0])) {
    foreach ($b[0] as $k => $v) {
        $c[$k] = $v;        
    }
}
echo '<pre>';print_r($c);echo '</pre>';
?>  

Output:

Array
(
    [size] => 6Y
    [quantity] => 15
)

Answer 2

Use call_user_func_array with array_merge

1. Json decode your string
2. Flatten the array

like this:

<?php
$a = '[{"size":"6Y","quantity":15}]';
$b = call_user_func_array('array_merge', json_decode($a,true));
print_r($b);

Output:

Array
(
    [size] => 6Y
    [quantity] => 15
)

Answer 3

Try this, use json_decode:

<?php
$a = '[{"size":"6Y","quantity":15}]';
$a = substr($a, 1, -1);
print_r((array)json_decode($a));
?>

Answer 4

$a = '[{"size":"6Y","quantity":15}]';
$v = json_decode($a);
print_r(array_values($v));
