note 123310 deleted from function.array-search by crell

Note Submitter: venkatesh dot ksnadar at gmail dot com ---- you need to be careful if you are using array_search() with unset() for deleting a value in the searched indexed // wrong way $checked = ["1", "2", "3"]; // array with numbers in double quotes unset($checked[array_search('on', $checked)]); // this deletes value at 0 index // array_search returns mixed data type, which means any type of data will be returned // in the above case it returned false and false is type casted to 0 // so it deletes the value at index zero the point to say is never use array_search() with unset() while deleting a value in an array using index.
