The results of the function db_conn1 must be passed as arguments to the function search_phrase. But what i get is the results of the db_conn1 function and throws me an error, directory or path not found... but actually it does exists... this is true cuz when i run this function seperately it gives me the correct result... i actually stored the results of db_conn1 function's results in an array and passed it to the search_phrase function...
