How to combine the keys and values of an array in PHP

Question

Say I have an array of key/value pairs in PHP:

array( 'foo' => 'bar', 'baz' => 'qux' );

What's the simplest way to transform this to an array that looks like the following?

array( 'foo=bar', 'baz=qux' );

i.e.

array( 0 => 'foo=bar', 1 => 'baz=qux');

In perl, I'd do something like

map { "$_=$hash{$_}" } keys %hash

Is there something like this in the panoply of array functions in PHP? Nothing I looked at seemed like a convenient solution.

Answer 1

function parameterize_array($array) {
    $out = array();
    foreach($array as $key => $value)
        $out[] = "$key=$value";
    return $out;
}

Answer 2

chaos' answer is nice and straightfoward. For a more general sense though, you might have missed the array_map() function which is what you alluded to with your map { "$_=$hash{$_}" } keys %hash example.

Answer 3

A "curious" way to do it =P

// using '::' as a temporary separator, could be anything provided
// it doesn't exist elsewhere in the array
$test = split( '::', urldecode( http_build_query( $test, '', '::' ) ) );
