Filesystem to XML class function is giving incorrect output.

[empiresolutions]

I'm trying to build my first PHP Class. After days of tweaking, im lost. I am used to working with functions and arrays, but wrapping them in classes is confusing me.

The following code is to return an Array Collection representative of a folder and sub folder in a directory of choice. It doesn't work. Throws an error "Call to undefined function: parse_dir()". It would be great if someone out there could see where im not correct.

I've been trying to follow the example provided at http://www.sephiroth.it/tutorials/fl...ct/page003.php

<?
class Tree {
    var $folders;
    var $files;
    var $name;
    // explicit actionscript package
    var $_explicitType = "tutorials.Tree";
}
 
class DirTree {
 
    /**
     * Get a tree of folders and files from a spec dir
     * @returns An ArrayCollection of Tree
     */
    function DirTree( $dir_tree ){
 
        $t = array();
        $_tree = parse_dir($dir_tree);
 
        for($a = 0; $a < count($_tree); $a++){
            $tree = new Tree();
            $tree->folders = $_tree[$a][0];
            $tree->files = $_tree[$a][1];
            $tree->name = $_tree[$a][2];
            $t[] = $tree;
        }
 
        return $t;
    }
 
    /**
     * Get a tree of folders and files from a spec dir
     * @returns An Array of Tree
     */
    function parse_dir( $folder ){
 
        $dir                = @opendir( $folder );
        $fname              = array_pop( explode( "/",$folder) );
        $fname              = empty( $fname ) ? "root" : str_replace( " ","_",$fname );
        $path               = "";
        $filecount          = 0;
        $foldercount        = 0;
        $xml                = "";
        $tree                = array();
        $limb                = array();
 
        while ( false != ( $item = @readdir( $dir ) ) ) {
 
            if( $item == "." || $item == ".." ) continue;
 
            if( is_dir( "$folder/$item" ) ){
 
                $tree[][$folder] = parse_dir( "$folder/$item");
                $foldercount++;
                $limb['folders'] = $foldercount;
                $filecount++;
                $limb['files'] = $filecount;
                continue;
 
            }
 
            $limb['name'] = $item;
        }
 
        $tree[] = $limb;
        return $tree;
 
    }
}
 
$class = new DirTree("path_to_folder"); // "../../example_folder"
echo $class->DirTree();
?>
 

Thanks.

i have made some updates from suggestions and still get errors. Here is new code.

<?
class Tree {
    var $folders;
    var $files;
    var $name;
    // explicit actionscript package
    var $_explicitType = "tutorials.Tree";
}
 
class DirTree {
 
    /**
     * Get a tree of folders and files from a spec dir
     * @returns An ArrayCollection of Tree
     */
    function DirTree( $dir_tree ){
 
        $t = array();
        $_tree = $this->parse_dir($dir_tree);
 
        for($a = 0; $a < count($_tree); $a++){
            $tree = new Tree();
            $tree->folders = $_tree[$a][0];
            $tree->files = $_tree[$a][1];
            $tree->name = $_tree[$a][2];
            $t[] = $tree;
        }
 
        return $t;
    }
 
    /**

    function parse_dir( $folder ){
 
        $dir                = @opendir( $folder );
        $fname              = array_pop( explode( "/",$folder) );
        $fname              = empty( $fname ) ? "root" : str_replace( " ","_",$fname );
        $path               = "";
        $filecount          = 0;
        $foldercount        = 0;
        $xml                = "";
        $tree                = array();
        $limb                = array();
 
        while ( false != ( $item = @readdir( $dir ) ) ) {
 
            if( $item == "." || $item == ".." ) continue;
 
            if( is_dir( "$folder/$item" ) ){
 
                $tree[][$folder] = parse_dir( "$folder/$item");
                $foldercount++;
                $limb['folders'] = $foldercount;
                $filecount++;
                $limb['files'] = $filecount;
                continue;
 
            }
 
            $limb['name'] = $item;
        }
 
        $tree[] = $limb;
        return $tree;
 
    }
}
 
$class = new DirTree();
 
/* view array  */
echo "<pre>";
print_r($class->DirTree("../../flashservices"));
echo "</pre>";
?>
 

Here is an XML view of what the structure should be like.

<folder name="root" folders="1" files="2">
    <file>advancedsettings.php</file>
    <file>adodbAdapter.php</file>
    <folder name="adapters" folders="1" files="5">
        <file>adodbAdapter.php</file>
        <file>arrayfAdapter.php</file>
        <file>arrayftAdapter.php</file>
        <file>fbsqlAdapter.php</file>
        <file>informixAdapter.php</file>
        <folder name="custom" folders="0" files="2">
            <file>CachedExecutionAction.php</file>
            <file>CachedGateway.php</file>
        </folder>
    </folder>
</folder>

Changed thread title to better match contents.

Looking good so far. What are you getting instead of what you wanted?

parse_dir() is a member of the class DirTree. As such, you will need to either call $this->parse_dir() or $obj->parse_dir() to access it.
