Check if the value “Glenn” exists in an array and output some text:
| <?php $people = array(“Peter”, “Joe”, “Glenn”, “Cleveland”); if (in_array(“Glenn”, $people)) { echo “Match found”; } else { echo “Match not found”; } ?> |
The in_array() function searches an array for a specific value.
Note: If the search parameter is a string and the type parameter is set to TRUE, the search will be case-sensitive.
