Question

I have an array that looks like this

Array
(  
    [0] => Array
        (
            [Title] => The Title
            [Price] => 700
            [Quantity] => 2
        )

)

Say I wanted to change the Quantity to 5 how would I do that if the array were stored in the variable $ItemArray?

Answer 1

Try $itemArray[0]['Quantity'] = 5;.

Basically, you have an array, $itemArray, which contains an associative array. To access that inside array, you simply use standard PHP array syntax: $itemArray[0].

Then, you need the Quantity field of that inner array. Using the nested array syntax, you append ['Quantity'] to the end of our previous statement, resulting in: $itemArray[0]['Quantity'].

At this point, you have the field you want, and you can use the normal = to set the field value.

$itemArray[0]['Quantity'] = 5;
