Combining syntax of array_search() and functionality of array_keys() to get all key=>value associations of an array with the given search-value:
<?php
function array_search_values( $m_needle, $a_haystack, $b_strict = false){
return
array_intersect_key( $a_haystack, array_flip( array_keys( $a_haystack, $m_needle, $b_strict)));
}
?>

Usage:
<?php
$array1
= array( 'pre'=>'2', 1, 2, 3, '1', '2', '3', 'post'=>2);
print_r( array_search_values( '2', $array1));
print_r( array_search_values( '2', $array1, true));
print_r( array_search_values( 2, $array1, true));
?>

Will return:
array(4) {
["pre"] =>
string(1) "2"
[1] =>
int(2)
[4] =>
string(1) "2"
["post"] =>
int(2)
}
array(2) {
["pre"] =>
string(1) "2"
[4] =>
string(1) "2"
}
array(2) {
[1] =>
int(2)
["post"] =>
int(2)
}
