1.2.462. Find Key Directly¶
There is no need to use foreach() to search for a key.
PHP offers two solutions : array_search() and array_keys(). Array_search() finds the first key that fits a value, and array_keys() returns all the keys.
<?php
$array = ['a', 'b', 'c', 'd', 'e'];
print array_search($array, 'c');
// print 2 => 'c';
print_r(array_keys($array, 'c'));
// print 2 => 'c';
?>
See also array_search and array_keys.
