mysql_* functions have been removed in PHP 7.

You now have two alternatives: MySQLi and PDO.

The following is a before (-) and after (+) comparison of a migration to the MySQLi alternative, taken straight out of working code:

-if (!$dbLink = mysql_connect($dbHost, $dbUser, $dbPass))
+if (!$dbLink = mysqli_connect($dbHost, $dbUser, $dbPass))

-if (!mysql_select_db($dbName, $dbLink))
+if (!mysqli_select_db($dbLink, $dbName))

-if (!$result = mysql_query($query, $dbLink)) {
+if (!$result = mysqli_query($dbLink, $query)) {

-if (mysql_num_rows($result) > 0) {
+if (mysqli_num_rows($result) > 0) {

-while ($row = mysql_fetch_array( $result, MYSQL_ASSOC )) {
+while ($row = mysqli_fetch_array( $result, MYSQLI_ASSOC )) {

-mysql_close($dbLink);
+mysqli_close($dbLink);
