Will It Vibe?Deprecated ext/mysql (mysql_*) function used
Part of Code Quality & Syntax, which counts for 20% of the overall score. When this check fires it deducts 8 points from that category, once per scan, no matter how many places it turns up.
What it detects
The entire ext/mysql extension (mysql_connect, mysql_query, ...) was removed in PHP 7.0. Code calling these functions either targets an ancient, unsupported PHP build or is dead code left over from a migration to mysqli/PDO, and will fatal-error under any current PHP version.
Why it matters
The entire ext/mysql extension (mysql_connect, mysql_query, and the rest of that function family) was removed in PHP 7.0. Code that still calls these functions will fatal-error with a "call to undefined function" on any currently supported PHP version, meaning this code path is either already dead and untested, or it is running on an unsupported, unpatched PHP build.
How to fix it
Port the calls to mysqli (mysqli_connect/mysqli_query, or the OOP mysqli API) or PDO. Both support prepared statements, which ext/mysql never did, so this is also a chance to fix any string-built queries at the same call sites. If the code is genuinely unused, delete it instead of migrating it.
