When executing a. php file under the PHP command line, the working directory of the Execution Environment (GETCWD ()) is the directory of the PHP Command Program (php.exe), so if you want to use a relative path within the file, switch the current working directory first.

Small test Program:

Copy Code code as follows:

<?php
$oldpath = GETCWD (); Original working directory Php.exe directory
$path = DirName (__file__);
ChDir ($path); Toggles the working directory to the directory where the current file resides
$fpath = "Forum/readme.txt";

$fp = fopen ($fpath, "a+b"); If you do not switch the working directory, you will report an error that cannot find the file
Fwrite ($FP, "OldPath:". $oldpath. " -newpath: ". GETCWD ());
Fclose ($FP);
?>

Programs that need to be executed regularly with Crotab will also have this problem. Refer to the following article:
