 There are two ways to let PHP handle multiple requests concurrently,​ server managed mode and self managed mode. In server managed mode, LiteSpeed Web Server dynamically spawns/​stops PHP processes. In this mode, an external application'​s "​Instances"​ setting should match the "Max Connections"​ configuration. To start PHP in self managed mode, "​Instances"​ should be set to "​1",​ while the "​LSAPI_CHILDREN"​ environment variable should be >1 and set to match the value of "Max Connections"​. In this mode the web server will start one PHP process, and this process will start/stop child PHP processes dynamically based on on demand. Self managed mode is preferred because all PHP processes can then share one memory block for opcode caching. ​ There are two ways to let PHP handle multiple requests concurrently,​ server managed mode and self managed mode.

-If "​LSAPI_CHILDREN"​ <=1, PHP will be started in server managed mode.+If "​LSAPI_CHILDREN" ​%<=%1, PHP will be started in server managed mode.
 Usually, there is no need to set the value of "​LSAPI_CHILDREN"​ over "​100"​. Usually, there is no need to set the value of "​LSAPI_CHILDREN"​ over "​100"​.
