<p>I have currently more than 100 connections in Sleep state.</p>

<p>Some connection must stay in Sleep state (and don't close) because it's permanent connection but some others (with a different user name) are from some php script and I want them to timeout very fast.</p>

<p>Is it possible to setup a wait_timeout per user? and if yes, How?</p>

I checked the
```
mysql.user
```
table and it doesn't look like there is a setting there for it:
```

Depending on whether you're using MySQLi or PDO, your PHP MySQL connections should either hang up when the request does, or be shared in a pool for the Apache process.
For example, with PDO, to turn off persistent connections (I think this is the default), connect to your DB with:
$pdo = new PDO($dsn, $user, $pass, Array(PDO::ATTR_PERSISTENT => false));
If you want your scripts to use persistent connections, but you have too many connections open to your database in sleep mode, you should think about configuring your Apache's
```
MaxServers
```
,
```
MaxSpareServers
```
,
```
MinSpareServers
```
and
```
StartServers
```
so that not so many hang around when they aren't needed.
