php计算整个目录大小的方法
本文实例讲述了php计算整个目录大小的方法。分享给大家供大家参考。具体实现方法如下:
/**
*Calculatethefullsizeofadirectory
*
*@authorJonasJohn
*@version0.2
*@paramstring$DirectoryPathDirectorypath
*/
functionCalcDirectorySize($DirectoryPath){
//Ireccomendusinganormalize_pathfunctionhere
//tomakesure$DirectoryPathcontainsanendingslash
//Todisplayagoodlookingsizeyoucanuseareadable_filesize
//function.
$Size=0;
$Dir=opendir($DirectoryPath);
if(!$Dir)
return-1;
while(($File=readdir($Dir))!==false){
//Skipfilepointers
if($File[0]=='.')continue;
//Gorecursivedown,oraddthefilesize
if(is_dir($DirectoryPath.$File))
$Size+=CalcDirectorySize($DirectoryPath.$File.DIRECTORY_SEPARATOR);
else
$Size+=filesize($DirectoryPath.$File);
}
closedir($Dir);
return$Size;
}
//使用范例:
$SizeInBytes=CalcDirectorySize('data/');
希望本文所述对大家的php程序设计有所帮助。
