I want to know all keys whose values are same.
I have below array:
[monday] => 10:00 - 11:00,
[tuesday] => 11:00 - 12:00,
[wednesday] => 10:00 - 11:00,
[friday] => 10:00 - 11:00,
[saturday] => 11:00 - 12:00,
[sunday] => 14:00 - 15:00,
monday/wednesday/friday = 10:00 - 11:00.
tuesday/saturday = 11:00 - 12:00.
sunday = 14:00 - 15:00.
Please help me.
Thanks in advance.
You can do a simple foreach loop and join a new array depending on values:
<?php
$worktimes = array(
'monday' => '10:00 - 11:00',
'tuesday' => '11:00 - 12:00',
'wednesday' => '10:00 - 11:00',
'friday' => '10:00 - 11:00',
'saturday' => '11:00 - 12:00',
'sunday' => '14:00 - 15:00'
);
$combined = array();
foreach ( $worktimes as $key => $value ) {
$combined[$value][] = $key;
}
print_r( $combined );
?>
Now you have a new array that holds you key with all the values that match it.
Array ( [10:00 - 11:00] => Array ( [0] => monday [1] => wednesday [2] => friday ) [11:00 - 12:00] => Array ( [0] => tuesday [1] => saturday ) [14:00 - 15:00] => Array ( [0] => sunday ) ) which is in fact, the answer of the question.
