Developing a FileSystem Client in PHP

[PeteH]

I don't understand why this topic is missing in your otherwise fairly extensive documentation?!?!

I'm not a PHP programmer but I need to evaluate ICE to implement an interface accross processor boundaries between a C++ server and Python/PHP clients.

I wonder if you have a PHP sample implementation of the basic FileSystem client resembling the functionality implemented in C++ and explained chapter 7?

Do you like this better?

Attached is a smal sample that I wrote but at present I get the error:

Fatal error: listRecursive(): unknown operation in c:\oracle\ora91\Apache\Apache\htdocs\filesystemcli ent.php on line 41

I can't see what is wrong.

Thanks Peter.

We don't have a good reason for omitting the filesystem example in PHP. We'll add this to the manual.

Here is the PHP code for the client:

<?php
Ice_loadProfile();

// Recursively print the contents of directory "dir"
// in tree fashion. For files, show the contents of
// each file. The "depth" parameter is the current
// nesting level (for indentation).

function listRecursive($dir, $depth = 0)
{
    $indent = str_repeat("\t", ++$depth);

    $contents = $dir->_list(); // list is a reserved word in PHP

    foreach ($contents as $i) {
        $dir = $i->ice_checkedCast("::Filesystem::Directory");
        $file = $i->ice_uncheckedCast("::Filesystem::File");
        echo $indent . $i->name() .
            ($dir ? " (directory):" : " (file):") . "\n";
        if ($dir) {
            listRecursive($dir, $depth);
        } else {
            $text = $file->read();
            foreach ($text as $j)
                echo $indent . "\t" . $j . "\n";
        }
    }
}

try
{
    // Create a proxy for the root directory
    //
    $base = $ICE->stringToProxy("RootDir:default -p 10000");

    // Down-cast the proxy to a Directory proxy
    //
    $rootDir = $base->ice_checkedCast("::Filesystem::Directory");

    // Recursively list the contents of the root directory
    //
    echo "Contents of root directory:\n";
    listRecursive($rootDir);
}
catch(Ice_LocalException $ex)
{
    print_r($ex);
}
?>

Take care,

You need to change $objDir->list() to $objDir->_list(). Since "list" is a reserved word in PHP, the Slice mapping prepends an underscore to its name. You can find a list of PHP's reserved words here:
