LEARN ABOUT PHP
each
EACH(3) 1 EACH(3)each - Return the current key and value pair from an array and advance the array cursorSYNOPSIS
array each (array &$array)
DESCRIPTION
Return the current key and value pair from an array and advance the array cursor.
After each(3) has executed, the array cursor will be left on the next element of the array, or past the last element if it hits the end of
the array. You have to use reset(3) if you want to traverse the array again using each.
PARAMETERS
o $array
- The input array.
RETURN VALUES
Returns the current key and value pair from the array $array. This pair is returned in a four-element array, with the keys 0, 1, key, and
value. Elements 0 and key contain the key name of the array element, and 1 and value contain the data.
If the internal pointer for the array points past the end of the array contents, each(3) returns FALSE.
EXAMPLES
Example #1
each(3) examples
<?php
$foo = array("bob", "fred", "jussi", "jouni", "egon", "marliese");
$bar = each($foo);
print_r($bar);
?>
$bar now contains the following key/value pairs:
Array
(
[1] => bob
[value] => bob
[0] => 0
[key] => 0
)
<?php
$foo = array("Robert" => "Bob", "Seppo" => "Sepi");
$bar = each($foo);
print_r($bar);
?>
$bar now contains the following key/value pairs:
Array
(
[1] => Bob
[value] => Bob
[0] => Robert
[key] => Robert
)
each(3) is typically used in conjunction with list(3) to traverse an array, here's an example:
Example #2
Traversing an array with each(3)
<?php
$fruit = array('a' => 'apple', 'b' => 'banana', 'c' => 'cranberry');
reset($fruit);
while (list($key, $val) = each($fruit)) {
echo "$key => $val
";
}
?>
The above example will output:
a => apple
b => banana
c => cranberry
Caution
Because assigning an array to another variable resets the original array's pointer, our example above would cause an endless loop
had we assigned $fruit to another variable inside the loop.
Warning
each(3) will also accept objects, but may return unexpected results. It's therefore not recommended to iterate though object proper-
ties with each(3).
