ARRAY_KEYS(3) 1 ARRAY_KEYS(3)
array_keys - Return all the keys or a subset of the keys of an array
SYNOPSIS
array array_keys (array $array, [mixed $search_value], [bool $strict = false])
DESCRIPTION
array_keys(3) returns the keys, numeric and string, from the $array.
If the optional $search_value is specified, then only the keys for that value are returned. Otherwise, all the keys from the $array are
returned.
PARAMETERS
o $array
- An array containing keys to return.
o $search_value
- If specified, then only keys containing these values are returned.
o $strict
- Determines if strict comparison (===) should be used during the search.
RETURN VALUES
Returns an array of all the keys in $array.
EXAMPLES
Example #1
array_keys(3) example
<?php
$array = array(0 => 100, "color" => "red");
print_r(array_keys($array));
$array = array("blue", "red", "green", "blue", "blue");
print_r(array_keys($array, "blue"));
$array = array("color" => array("blue", "red", "green"),
"size" => array("small", "medium", "large"));
print_r(array_keys($array));
?>
The above example will output:
