Description
Description
Function getcwd() returns different results with php.exe and php-cgi.exe
Via php.exe it returns drive letter in upper case.
Via php-cgi.exe it returns drive letter in lower case.
The following code:
<?php
function print_backtrace()
{
print debug_backtrace()[0]["file"];
}
print getcwd() . "\n";
print_backtrace();
Resulted in this output:
via php.exe
C:\test
C:\test\test.php
but via php-cgi.exe
c:\test
C:\test\test.php
But I expected this output in both cases:
C:\test
C:\test\test.php
PHP Version
PHP 8.1.6
Operating System
Windows 11 21H2

Research direction
Reproduce the report on Windows 11 with PHP 8.1.6 using both php.exe and php-cgi.exe, running the provided getcwd() and debug_backtrace() script. Compare the drive-letter casing in both outputs and trace the differing working-directory behavior in the PHP source. Done means both executables return the same drive-letter casing.
