(PHP3 >= 3.0.3, PHP4 ) array_walk --
Apply a user function to every member of an array.
Descriptionint array_walk (array arr, string func, mixed userdata)
Applies the function named by func to each
element of
arr. func will be
passed array value as the first parameter and array key as the
second parameter. If userdata is
supplied, it will be passed as the third parameter to the user
function.
If func requires more than two or three
arguments, depending on userdata, a
warning will be generated each time
array_walk() calls
func. These warnings may be suppressed by
prepending the '@' sign to the array_walk()
call, or by using error_reporting(). Anmerkung:
If func needs to be working with the
actual values of the array, specify that the first parameter of
func should be passed by reference. Then
any changes made to those elements will be made in the array
itself.
Anmerkung:
Passing the key and userdata to func was added in 4.0.
Beispiel 1. array_walk() example
$fruits = array("d"=>"lemon","a"=>"orange","b"=>"banana","c"=>"apple");
function test_alter( &$item1, $key, $prefix ) {
$item1 = "$prefix: $item1";
}
function test_print( $item2, $key ) {
echo "$key. $item2<br>\n";
}
array_walk( $fruits, 'test_print' );
array_walk( $fruits, 'test_alter', 'fruit' );
array_walk( $fruits, 'test_print' );
