You can use this code in windows or if you system has no posix support:
<?php
if (!function_exists('posix_getpid')) {
function posix_getpid() {
return getmypid();
}
}
(PHP 4, PHP 5, PHP 7, PHP 8)
posix_getpid — 返回当前进程 id
Return the process identifier of the current process. 返回当前进程的 id
此函数没有参数。
返回进程 id 号，是整型（int）。
Example #1 posix_getpid() 的使用例子
<?php
echo posix_getpid(); //8805
?>
You can use this code in windows or if you system has no posix support:
<?php
if (!function_exists('posix_getpid')) {
function posix_getpid() {
return getmypid();
}
}
You can also try using getmypid() instead.
In order to use posix_getpid on Fedeora 11 and up you have to install php-process
# yum install php-process
Since upgrading fedora 10 to 12, I discovered that posix_getpid() disappeared and not compiled in by default, as it specifies here.
It turns out that it had been moved into package php-process.
Just do "yum install php-process", and all should be sweet again.
Hope this saves someone half an hour of research.
