From: sam at freepeers dot com Operating system: Windows 2000 PHP version: 4.3.2 PHP Bug Type: Program Execution Bug description: Program Executation Functions fails in certain cases
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 .
