Using Linux/PHP 4.3.2 CLI:
$fileID = fopen('myfile.txt', 'r'); // WORKS JUST FINE
Using Linux/PHP 4.3.8 CLI:
$fileID = fopen('myfile.txt', 'r'); // THROWS WARNING 'no such file or directory "myfile.txt"
Using Windows XP/PHP 5.0.4 CLI:
$fileID = fopen('myfile.txt', 'r'); // THROWS WARNING 'no such file or directory "myfile.txt"
In all three cases this script, let's call it myscript.php, resides in the exact same directory as "myfile.txt". Both scripts have permissions of 0644, same owner, same group (Unix).
For the Windows problem I managed to use a coding solution that will use the absolute path that is generated within $_SERVER['PHP_SELF'] (which apparently only occurs within Windows - have never seen that variable populated when using a UNIX-based OS):
if ($_ENV['windir'] || $_SERVER['windir']) {
$path = substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['PHP_SELF'], '/') + 1);
} else {
$path = '';
}
This, however, will produce no absolute path information for UNIX-based OS using "myscript.php" to access "myfile.txt". So using older versions of PHP as recent as PHP 4.3.8 within UNIX (Linux), "$fileID = fopen('myfile.txt', 'r');" you have to extract from $argv[0], provided you are using CLI PHP and you just happen to NOT be in the directory where "myscript.php" is housed, otherwise, you obviously get no absolute path info to locate "myfile.txt", and yes, when tested in PHP 4.3.11 and PHP 5.0.4, I constantly got the warning "No such file or directory: "myfile.txt"" even though it's clearly there with myscript.php.
Bottom line: Is there a foolproof way of always obtaining the absolute path of something using CLI PHP; or... what other alternatives have you all come up with using CLI PHP to always reliably locate a file that happens to be in the same directory as your script?
Thanx
