Stop Rolling Your Own

Seriously. Stop it. Or you’ll end up with garbage like this, in which a developer writes two separate functions for converting JSON to an array, only one of which is compatible with json_decode. Yes, both are in production.

<?php

function jsonToArray($jsonData)
{

    $newArray = array();

    // remove first and last []
    $length = strlen($jsonData) - 2;
    $jsonString = substr($jsonData, 1, $length);

    if ($jsonString != "") {
        // tokenize, using , as a divider
        $newArray = explode(",", $jsonString);
    }
    return $newArray;
}

// Converts JSON data string to PHP array
// Assumes this format: ["Some text","Even more text"]

    $lastArray = array();

    for ($i = 0; $i < sizeof($newArray); $i++) {

        $thisLength = strlen($newArray[$i]) - 2;
        $lastArray[] = substr($newArray[$i], 1, $thisLength);
    }
    return $lastArray;
}
