php读取大于2G文件解决方法

Functions fail on large files (filesize,is_file,is_dir)

Description:
------------
Error:
(errno=75 - Value too large for defined data type)

Functions:
is_file
is_dir
filesize

Premise:
size of file is greater than 2GB.

A workaround for this is:

$filesize=exec("ls -l '$yourfile' | awk '{print $5}'");

function is_dir_LFS($path){
return (('d'==substr(exec("ls -dl '$path'"),0,1))?(true):(false));
}
