规范化/标准路径根到 CLI/WEB

Question

I have this short script to detect the user usage environment and try to normalize the root path:

Located in C:\xampp\htdocs\dev\t2\Last-Hammer\configs\const\loader.php

$env= '';
if (php_sapi_name() == 'cli') {
    $env= 'cli';
    if (!isset($_SERVER['PWD'])) {
        $path = dirname(__DIR__).'\\';
    } else {
        $path = dirname($_SERVER['PWD']);
    }
} else {
    $env= 'web';
    $path = $_SERVER['DOCUMENT_ROOT'];
}
echo $path;
echo PHP_EOL;
echo $env;
file_get_contents($path.'configs/const/client.xml')

i use it from 2 diferent files: index.php that wor well in root folder but trying to use it from a sub-directory like this /dev/cron.php

cron.php content:

$path = (!isset($_SERVER["PWD"]) ? dirname(__DIR__).'\\' : dirname($_SERVER["PWD"]));
require_once $path.'/configs/const/loader.php';

i get this output

//from Web environment 
C:/xampp/htdocs/dev/t2/Last-Hammer/ 
web

and

//from CLI environment 
C:\xampp\htdocs\dev\t2\Last-Hammer 
cli

the problem is that this work correctly from Web environment but not work correctly in CLI, when i try to execute like: php cron.php code try to make a file_get_contents... like this using cli get this error:

PHP Warning: file_get_contents(C:\xampp\htdocs\dev\t2\Last-Hammer\configs\configs/const/client.xml): failed to open stream: No such file or directory in C:\xampp\htdocs\dev\t2\Last-Hammer\configs\const\loader.php on line 24

Warning: file_get_contents(C:\xampp\htdocs\dev\t2\Last-Hammer\configs\configs/const/client.xml): failed to open stream: No such file or directory in C:\xampp\htdocs\dev\t2\Last-Hammer\configs\const\loader.php on line 24

what is expected is that both for CLI or WEB, the root of the project is similar to: C:/xampp/htdocs/dev/t2/Last-Hammer/ and does not change constantly in the case of CLI depending on where it is executed the php file, as root could set in CLI. regardless of where it runs.

Answer 1

You are lacking trailing "\" on cli case. to uniform both, you could use str_replace():

$env= '';
if (php_sapi_name() == 'cli') {
    $env= 'cli';
    if (!isset($_SERVER['PWD'])) {
        $path = dirname(__DIR__).'\\';
    } else {
        $path = dirname($_SERVER['PWD']).'\\';
    }
} else {
    $env= 'web';
    $path = $_SERVER['DOCUMENT_ROOT'];
}
$path = str_replace( '\\', '/', $path );
echo $path;
echo PHP_EOL;
echo $env;
file_get_contents($path.'configs/const/client.xml')

Answer 2

define in your main scripts:

define('DOCROOT', '../'); // this in your cron.php
define('DOCROOT', './'); // this in your index.php

Just use relative paths:

$path = DOCROOT;
file_get_contents($path.'configs/const/client.xml')
