Witch color by number is an activity that combines the fun of coloring with the concept of following numbered instructions. This activity is popular among children and adults alike as it provides a sense of accomplishment and relaxation. The premise of witch color by number is simple. A picture of a witch is divided into various shapes and each shape is assigned a number. The participant uses a color key or legend to identify which color corresponds to each number. They then color each shape within the witch image according to the corresponding number.

$func (. $values );
//returns 3
?>

Just in time for Halloween, or the pagan festival Samhain, Denver s Witch Collective threw the first official Witchcraft Mercantile to benefit the Victim Offender Reconciliation Program. They keep overhead low and charitable donations high by picking venues that will host them free-of-charge and by mandating artists donate, rather than pay booth fees.

They then color each shape within the witch image according to the corresponding number. By following the numbered instructions, the participant gradually reveals a vibrant and colorful picture of a witch. Witch color by number offers a range of benefits.

call_user_func_array

Calls the callback given by the first parameter with the parameters in args .

Parameters

The callable to be called.

The parameters to be passed to the callback, as an array.

If the keys of args are all numeric, the keys are ignored and each element will be passed to callback as a positional argument, in order.

If any keys of args are strings, those elements will be passed to callback as named arguments, with the name given by the key.

It is a fatal error to have a numeric key in args appear after a string key, or to have a string key that does not match the name of any parameter of callback .

Return Values

Returns the return value of the callback, or false on error.

Examples

Example #1 call_user_func_array() example

function foobar ( $arg , $arg2 ) echo __FUNCTION__ , " got $arg and $arg2 \n" ;
>
class foo function bar ( $arg , $arg2 ) echo __METHOD__ , " got $arg and $arg2 \n" ;
>
>

// Call the foobar() function with 2 arguments
call_user_func_array ( "foobar" , array( "one" , "two" ));

// Call the $foo->bar() method with 2 arguments
$foo = new foo ;
call_user_func_array (array( $foo , "bar" ), array( "three" , "four" ));
?>

The above example will output something similar to:

foobar got one and two foo::bar got three and four

Example #2 call_user_func_array() using namespace name

class Foo static public function test ( $name ) print "Hello < $name >!\n" ;
>
>

call_user_func_array ( __NAMESPACE__ . '\Foo::test' , array( 'Hannes' ));

call_user_func_array (array( __NAMESPACE__ . '\Foo' , 'test' ), array( 'Philip' ));

The above example will output something similar to:

Hello Hannes! Hello Philip!

Example #3 Using lambda function

$func = function( $arg1 , $arg2 ) return $arg1 * $arg2 ;
>;

var_dump ( call_user_func_array ( $func , array( 2 , 4 )));

The above example will output:

int(8)

Example #4 Passing values by reference

function mega (& $a ) $a = 55 ;
echo "function mega \$a= $a \n" ;
>
$bar = 77 ;
call_user_func_array ( 'mega' ,array(& $bar ));
echo "global \$bar= $bar \n" ;

The above example will output:

function mega $a=55 global $bar=55

Example #5 call_user_func_array() using named arguments

function foobar ( $first , $second ) echo __FUNCTION__ , " got $first and $second \n" ;
>

// Call the foobar() function with named arguments in non-positional order
call_user_func_array ( "foobar" , array( "second" => "two" , "first" => "one" ));

// Call the foobar() function with one named argument
call_user_func_array ( "foobar" , array( "foo" , "second" => "bar" ));

// Fatal error: Cannot use positional argument after named argument
call_user_func_array ( "foobar" , array( "first" => "one" , "bar" ));

The above example will output something similar to:

foobar got one and two foobar got foo and bar Fatal error: Uncaught Error: Cannot use positional argument after named argument

Notes

Note:

Callbacks registered with functions such as call_user_func() and call_user_func_array() will not be called if there is an uncaught exception thrown in a previous callback.

Using PHP 8, call_user_func_array call callback function using named arguments if an array with keys is passed to $args parameter, if the array used has only values, arguments are passed positionally.

function test ( string $param1 , string $param2 ): void
echo $param1 . ' ' . $param2 ;
>

$args = [ 'hello' , 'world' ];
//hello world
call_user_func_array ( 'test' , $args );

$args = [ 'param2' => 'world' , 'param1' => 'hello' ];
//hello world
call_user_func_array ( 'test' , $args );

$args = [ 'unknown_param' => 'hello' , 'param2' => 'world' ];
//Fatal error: Uncaught Error: Unknown named parameter $unknown_param
call_user_func_array ( 'test' , $args );
?>

As of PHP 5.6 you can utilize argument unpacking as an alternative to call_user_func_array, and is often 3 to 4 times faster.

function foo ( $a , $b ) return $a + $b ;
>

$func = 'foo' ;
$values = array( 1 , 2 );
call_user_func_array ( $func , $values );
//returns 3

$func (. $values );
//returns 3
?>

It's quite interesting reading the notes in this page especially the one that mentions the difference between argument unpacking being significantly faster than calling `call_user_func_array()` directly by admin at torntech dot com.

This is true for PHP 5 but as from PHP 7.0+, there is no significant difference in the run-time between these two mechanisms of operation. The time taken is almost, if not the same for both operations, so this is already something that tells me that the PHP run-time environment has changed quite a lot (for the PHP 7 rewrite).

I used the example from admin at torntech dot com to check this hypothesis.

call_user_func_array (array( __NAMESPACE__ . '\Foo' , 'test' ), array( 'Philip' ));
