我通过将当前计数存储在文件中来制作一个简单的页面加载计数器.这就是我想要这样做的方式：
>锁定文件(flock)
>读取当前计数(fread)
>增加它()
>写新计数(fwrite)
>解锁文件/关闭它(flock / fclose)
这可以在不失锁的情况下完成吗？
如上所述,你可以使用FLock.一个简单的例子是：
//Open the File Stream
$handle = fopen("file.txt","r+");
//Lock File,error if unable to lock
if(flock($handle,LOCK_EX)) {
$count = fread($handle,filesize("file.txt")); //Get Current Hit Count
$count = $count + 1; //Increment Hit Count by 1
ftruncate($handle,0); //Truncate the file to 0
rewind($handle); //Set write pointer to beginning of file
fwrite($handle,$count); //Write the new Hit Count
flock($handle,LOCK_UN); //Unlock File
} else {
echo "Could not Lock File!";
}
//Close Stream
fclose($handle);
