array_walk
ARRAY_WALK(3) 1 ARRAY_WALK(3)array_walk - Apply a user supplied function to every member of an arraySYNOPSIS
bool array_walk NULL (array &$array, callable $callback, [mixed $userdata])
DESCRIPTION
Applies the user-defined $callback function to each element of the $array array.
array_walk(3) is not affected by the internal array pointer of $array. array_walk(3) will walk through the entire array regardless of
pointer position.
PARAMETERS
o $array
- The input array.
o $callback
- Typically, $callback takes on two parameters. The $array parameter's value being the first, and the key/index second.
Note
If $callback needs to be working with the actual values of the array, specify the first parameter of $callback as a refer-
ence. Then, any changes made to those elements will be made in the original array itself.
Note
Many internal functions (for example strtolower(3)) will throw a warning if more than the expected number of argument are
passed in and are not usable directly as a $callback.
Only the values of the $array may potentially be changed; its structure cannot be altered, i.e., the programmer cannot add, unset
or reorder elements. If the callback does not respect this requirement, the behavior of this function is undefined, and unpre-
dictable.
o $userdata
- If the optional $userdata parameter is supplied, it will be passed as the third parameter to the $callback.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
ERRORS /EXCEPTIONS
If function $callback requires more parameters than given to it, an error of level E_WARNING will be generated each time array_walk(3)
calls $callback.
EXAMPLES
Example #1
array_walk(3) example
<?php
$fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple");
function test_alter(&$item1, $key, $prefix)
{
$item1 = "$prefix: $item1";
}
function test_print($item2, $key)
{
echo "$key. $item2<br />
";
}
echo "Before ...:
";
array_walk($fruits, 'test_print');
array_walk($fruits, 'test_alter', 'fruit');
echo "... and after:
";
array_walk($fruits, 'test_print');
?>
The above example will output:
Before ...:
d. lemon
a. orange
b. banana
c. apple
d. fruit: lemon
a. fruit: orange
b. fruit: banana
c. fruit: apple
