ID: 25361 Updated by: [EMAIL PROTECTED] Reported By: sam at freepeers dot com -Status: Open +Status: Bogus Bug Type: Program Execution Operating System: Windows 2000 PHP Version: 4.3.2 New Comment:
PHP uses "cmd.exe /c" for executing programs under windows. You can try your examples on command line: cmd.exe /c "your long command" "another file" And you'll see it does not work. This is not PHP problem but yet another windows problem. You must always use the '8.3' format of the paths/filenames. Previous Comments: ------------------------------------------------------------------------ [2003-09-02 11:07:00] sam at freepeers dot com Description: ------------ Running PHP on Windows 2000 with IIS 5. Basic program executation does not work in certain cases. This is ok: $output = `C:\executable.exe C:\\file1.txt`; Now, lets suppose that both the filename and the executable names contain spaces, and therefore each are to be enclosed in quotes. Then it fails: This is not ok: $output = `"C:\executable.exe" "C:\\file1.txt"`; This is ok again: $output = `C:\executable.exe "C:\\file1.txt"`; This is also ok: $output = `"C:\executable.exe" C:\\file1.txt`; So, the problem arises when BOTH the command and the file are enclosed in quotes. In some cases you do need to enclose both the command and the file in quotes. You will not be able to. This affects all forms of command execution (exec, system, backticks...) Reproduce code: --------------- 1. Create file called "Test.txt" and put it into C: drive. Put some random text in it. 2. Try this code: <?php $output = ""; $output = `more C:\\Test.txt`; echo "Test.txt contains $output. This works<br><br>"; $output = ""; $output = `"more" C:\\Test.txt`; echo "Test.txt contains $output. This works<br><br>"; $output = ""; $output = `more "C:\\Test.txt"`; echo "Test.txt contains $output. This works<br><br>"; $output = ""; $output = `"more" "C:\\Test.txt"`; echo "Test.txt contains $output. This does not works<br><br>"; ?> Expected result: ---------------- Test.txt contains Contents of file. . This works Test.txt contains Contents of file. . This works Test.txt contains Contents of file. . This works Test.txt contains Contents of file. . This does not works Actual result: -------------- Test.txt contains Contents of file. . This works Test.txt contains Contents of file. . This works Test.txt contains Contents of file. . This works Test.txt contains . This does not works ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25361&edit=1
