PHP Returning Multiple Values

suarve · 28 Sep 2009 at 10:47

Lets say I have a simple function that queries a database for 4 values. If i want to return these four values for use on a page is the most efficient way to return these values as an array and use the list function? E.g

PHP:

function ocuk(1) {
//do database stuff
return array($1, $2, $3, $4);
}

//then on the actual page where IO need these vars
list($1, $2, $3, $4) = ocuk(1);

//etc.

It's the only way.

Depend's what you wish to do with the data, you could return it as an ARRAY, OBJECT, JSON, XML the list could go on

ARRAY or OBJECT are the most common way you would want to do it in the example above.

(OBJECT = HASH/Associated Array)

Just stick the function response into a VAR and interface with it directly.

PHP:

    $val = ocuk();
    echo $val[0] . ' ' . $val[1];

You could use pass by reference; http://us2.php.net/manual/en/language.references.pass.php
