I have been trying to convert the fields from a mysql_fetch_array (that are urlencoded) to urldecode before converting to JSON (json_encode)

Here's what I'm working with that doesn't work:The output is still urlencoded

$query = "SELECT * FROM table WHERE tableId=$tableId";
$result = mysql_fetch_array(mysql_query($query));
foreach($result as $value) {
    $value = urldecode($value);
}
$jsonOut = array();
$jsonOut[] = $result;
echo (json_encode($jsonOut));

Any ideas?

yeah....! you're not updating $result with the value returned by the function. $value needs to be passed by reference.

foreach($result as &$value) {
    $value = urldecode($value);
}

or

foreach($result as $i => $value) {
    $result[$i] = urldecode($value);
}

when you do this... 

foreach($result as $value) {
    $value = urldecode($value);
}

The result of the function is lost at at iteration of the foreach. You're trying to update each value stored in $result but that's not happening.

  • Also take note that the code only fetches one row from your query. I'm not sure if that's by design or not.

Try:

$query = "SELECT * FROM table WHERE tableId=$tableId";
$result = mysql_query($query);
$value = array();
while($row = mysql_fetch_array($result))
$value[] = urldecode($row);
}
$jsonOut = array();
$jsonOut[] = $result;
echo (json_encode($jsonOut));
