How to cast array elements to strings in PHP?

If I have a array with objects:

$a = array($objA, $objB);

(each object has a __toString()-method)

How can I cast all array elements to string so that array $a contains no more objects but their string representation? Is there a one-liner or do I have to manually loop through the array?

Solution

  • A one-liner:

    $a = array_map('strval', $a);
// strval is a callback function

    See PHP DOCS:

    array_map

    strval
