Mysqli is not working in php version 7

## By using this function we can reduce errors and can work using mysql instead of mysqli.

<?php
if (PHP_VERSION_ID > 59999) 
{
    function mysql_connect($a,$b,$c,$d=null) { return mysqli_connect($a,$b,$c,$d); }

    function mysql_query($a,$b) { return mysqli_query($b,$a); }

    function mysql_affected_rows($a){return mysqli_affected_rows($a);}

    function mysql_close($a){return mysqli_close($a); }

    function mysql_fetch_assoc($a) { return mysqli_fetch_assoc($a); }

    function mysql_free_result ($a) { mysqli_stmt_free_result($a); }

    function mysql_select_db ($a,$b) { mysqli_select_db($b,$a); }
}

?>
