# getmypid

(PHP 3, PHP 4, PHP 5)

getmypid -- Gets PHP's process ID

## 说明

int getmypid ( void )

Gets the current PHP process ID.

## 返回值

Returns the current PHP process ID, or `FALSE` on error.

## 注释

警告
Process IDs are not unique, thus they are a weak entropy source. We recommend against relying on pids in security-dependent contexts.
