Question
Let say i have function:
<?php
function myFunction($param1, $param2, /*0 or more extra args*/) {
// do something with $param1 & $param2
$args = func_get_args();
$other_args = array_slice($args, 2); // get the dynamic args
// do something with $other_args
}
?>
this enables to call:
<?php
myFunction($param1, $param2); // or
myFunction($param1, $param2, $param3); // or
myFunction($param1, $param2, $param3, $param4);
?>
But i want to know if it possible to to take an array of args and pass them into the function e.g:
<?php
$extra_args = array($param3, $param4); // this could also be
$extra_args = array($param3, $param4, $param5); // or any length array
?>
i would like to pass them as separate params into my function e.g
<?php
myFunction($param1, $param2 /* other args split up */);
?>
Thanks in advance!
Solution
Yeap - call_user_func_array()
'.
http://www.php.net/manual/en/function.call-user-func-array.php
Takes two arguments - the function name (as a string - or possibly, in PHP >= 5.3, an anonymous function, not sure) and an array of params.
Or for methods, forward_static_call_array()
http://www.php.net/manual/en/function.forward-static-call-array.php
PHP's answer to JS's function.prototype.apply()
:)
OTHER TIPS
call_user_func_array('myFunction',
array_merge(
array($param1,$param2),
$extra_args));
