Php command line (cli) to execute the relative path of the PHP script file solution

This article mainly introduces how to execute the relative path of the php script file under the PHP command line (cli), especially when running the PHP script in crontab, you can solve the problem by referring to the methods described in this article. For more information, see The php command line. when using the PHP file, the working directory of the Execution Environment (getcwd (logging handler is the directory where the PHP command program (php.exe) is located. to use the relative path in the file, you must switch the current working directory first.

Small test program:

The code is as follows:

<? Php
$ Oldpath = getcwd (); // The directory where the original working directory php.exe is located
$ Path = dirname (_ FILE __);
Chdir ($ path); // switch the working directory to the directory where the current file is located
$ Fpath = "forum/readme.txt ";

$ Fp = fopen ($ fpath, "a + B"); // If you do not switch the working directory, the file cannot be found.
Fwrite ($ fp, "oldpath:". $ oldpath. "-newpath:". getcwd ());
Fclose ($ fp );
?>

This problem also occurs for programs that require regular crotab execution. Refer to the following article:

You have written a script using the php script and need to run it regularly in crontab, but the following error occurs:

Try solution 1 add the following code

The code is as follows:

// Setting include path
$ Cur_dir = getcwd ();
$ Cur_dir = $ basedir = dirname (_ FILE __);
$ Path = ini_get ('include _ path ');
Ini_set ("include_path", "$ cur_dir: $ path ");
$ Path = ini_get ('include _ path ');
// Echo $ path;
Require (../class/a. php)
Require (../class/B. php)
...............

Operation failed

Try solution 2 Add the following code

The code is as follows:

The code is as follows:

$ Cur_dir = dirname (_ FILE __);
Chdir ($ cur_dir );
Require (../class/a. php)
Require (../class/B. php)

Running successful

Summary: If you run the php script in crontab in the relative directory of require, you must enter the directory where the script is located.
