Check if mysql query found results PHP -


how check if found results in mysql query in php

for eg

$usersearch=mysql_query("select * users username=$searchboxinput"); if($usersearch==successfull){ //what happens when successfull } else{ //what happens when unsuccessfull }

so if found user matching $searchboxinput , vice vera

use mysql_num_rows()

if(mysql_num_rows($usersearch) > 0){ //what happens when successfull } else{ //what happens when unsuccessfull }

fyi, you shouldn't use mysql_* functions in new code. no longer maintained and officially deprecated. see red box? learn prepared statements instead, , use pdo or mysqli - this article decide which. if choose pdo, here tutorial.

you may open sql injections.
