Search value in php array and get all keys

Question

Is there any better (= quicker ) solution to get all keys of value in array than foreach loop with if?

$array = array(\'apple\', \'orange\', \'pear\', \'banana\'         


        

Answer 1

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)));
}

$array = array('apple', 'orange', 'pear', 'banana', 'apple',
'pear', 'kiwi', 'kiwi', 'kiwi');

print_r( array_search_values( 'kiwi', $array,true));

Answer 2

Alternatively, you could also use array_keys in this case, and providing the second parameter needle:

$array = array('apple', 'orange', 'pear', 'banana', 'apple', 'pear', 'kiwi', 'kiwi', 'kiwi');
$searchObject = 'kiwi';
$keys = array_keys($array, $searchObject);
print_r($keys);

Sample Output

Answer 3

Try this :)

<?php
    $array = array('apple', 'orange', 'pear', 'banana', 'apple','pear', 'kiwi', 'kiwi', 'kiwi');
    $count = count($array);
    $str_to_search = 'kiwi';
    for($i=0;$i<$count;$i++){
        if($array[$i] == $str_to_search){
            echo $i.",";
        }
    }
?>
