I have an array of data created by a form that and I would like find out if it contains a specific value and let the user know that it is there. This is my array:
Array ( [0] => kitchen [1] => bedroom [2] => living_room [3] => dining_room)
and I would like do something like:
if(Array contains 'kitchen') {echo 'this array contains kitchen';}
What is the best way to do the above???
Use the in_array() function.
ReplyDelete$array = array('kitchen', 'bedroom', 'living_room', 'dining_room');
if (in_array('kitchen', $array)) {
echo 'this array contains kitchen';
}
See in_array
ReplyDelete<?php
$arr = array( [0] => kitchen [1] => bedroom [2] => living_room [3] => dining_room) ;
if (in_array("kitchen", $arr))
{
echo "'kitchen' is in \$arr";
}
?>
if (in_array('kitchen', $rooms) ...
ReplyDeleteYou need to use a search algorithm on your array. It depends on how large is your array, you have plenty of choices on what to use. Or you can use on of the built in functions:

ReplyDeletebool in_array ( mixed $needle , array $haystack [, bool $strict = FALSE ] )
Searches haystack for needle using loose comparison unless strict is set.
