Question

Let’s say I have this array,

$array = array(
    'name' => 'hermet',
    'emails' => array ('[e-mail]',
                     '[e-mail]');
);

So this way echo $array ['name'] == 'hermet' prints true. I would like to know if there is a function already embedded in PHP that let me do this:

echo $name == 'hermet'; // obviously 'false'

foreach ($array as $key => $value) {
    $aux = $key;
    $$aux = $value; 
}   

echo $name == 'hermet'; // now prints 'true'

It seems to work even with a multidimensional array but I don’t know if PHP has already any function to do that.

Thank you in advance.

You might be looking for extract

$array = array(
    'name' => 'hermet',
    'emails' => array ('[e-mail]',
                     '[e-mail]')
);

extract($array);

var_dump($emails);
echo $name;

— EDIT: If you are concerned about Paul’s remark, supply EXTR_SKIP to the second argument of extract, that way it won’t overwrite variable in case you’ve already defined it prior to calling extract.

$name = 'jason';
extract($array, EXTR_SKIP);

echo $name; // still 'jason'
