equal function String.fromCharCode in PHP

Posted in PHP, actionscript 3 on February 17th, 2010 by admin – Be the first to comment

Hey it was problem before I see this solution, to pass charactes to PHP like numbers, basicly because Flash use fromCharCode in UTF-8 format and PHP do chr function work in ASCII.

So here is the script solution:

    foreach ($arr as $key => $val) {
        if ($n >= $val) { // add byte to the 'char' array
            $char[] = ord($ch{$key}) - 128;
            $range  = $val;
        } else {
            break; // save some e-trees
        }
    }

    $retval = ($n - $range) * pow(64, sizeof($char));

    foreach ($char as $key => $val) {
        $pow = sizeof($char) - ($key + 1); // invert key
        $retval += $val * pow(64, $pow);   // dark magic

Flash video Player Snapshot

Posted in PHP, actionscript 3, projects & snippets on September 14th, 2009 by admin – Comments Off

Hi I have recently working on saving different format images from flash. My previous work on this script was: Image Encode with Flash and PHP. Here you can create snapshots from video source.

Example

In this example you can save exported images also in your computer. I like this example more, because you can get different images, not boring same image again.

Screenshots:
snapshot file 1
snapshot file 2
snapshot file 3

Image Encode with Flash and PHP

Posted in PHP, actionscript 3 on September 10th, 2009 by admin – Comments Off

hi, this is a little project to save export/save images from flash.

This application allow you to see how to export in different image formats like: png, jpg and bmp.

I create class ImageCreator, whit it it’s this easy create images on server. You call the class like this:

1
2
var imagecreator:ImageCreator = new ImageCreator(image_spr, ImageCreator.EXPORT_TYPE_PNG, name);
imagecreator.addEventListener(ImageCreator.EVENT_COMPLETE_SAVING, completeWritingEvent);

Event ImageCreator.EVENT_COMPLETE_SAVING, will be dispatched when image is correctly saved on your server.
This is ImageCreator Class

Getting data from XML, AS3

Posted in PHP, actionscript 3 on June 16th, 2009 by admin – Comments Off

Actionscript3 & PHP & MySQL & XML

I’m gonna post series of tutorials:

Getting data from XML, AS3
Getting data from MySQL, AS3 + PHP + MySQL file
Uploading file with AS3 + PHP
Send email with AS3 + PHP

How to parse a simple XML file. This is our structure:

<?xml version="1.0" encoding="utf-8" ?>
<data>
    <users>
        <user>
            <id>18</id>
            <name>bobanman</name>
            <avatar><![CDATA[]]></avatar>
            <registerData>13-07-2008</registerData>
            <email>bobanman@msn.com</email>
        </user>
        <user>
            <id>20</id>
            <name>ilya</name>
            <avatar><![CDATA[]]></avatar>
            <registerData>15-07-2008</registerData>
            <email>ilya@asymmetric.co.il</email>
        </user>
    </users>
</data>

First we will build XML parser. This is my favorite ways to parse it like this:

1

4

// parce XML
private function parseXML($rawData_:String):void {
    var xmldoc:XMLDocument = new XMLDocument();
    xmldoc.ignoreWhite = true;
    xmldoc.parseXML($rawData_);
   
    var out:Array = [];
    const imax:int = xmldoc.firstChild.firstChild.childNodes.length;
    for (var i:int = 0; i < imax; i++ ) {
        //collect data from XML
        out[i] = getUserDTO(xmldoc.firstChild.firstChild.childNodes[i]);
    }
   
    // all user data goes here :)
    trace(out);
}

// create UserDTO from XMLNode
private function getUserDTO($xmlNode_:XMLNode):UserDTO {
    return new UserDTO(int(XMLNode($xmlNode_.childNodes[0]).firstChild.toString()),
    XMLNode($xmlNode_.childNodes[1]).firstChild.toString(),
    XMLNode($xmlNode_.childNodes[2]).firstChild.toString(),
    XMLNode($xmlNode_.childNodes[3]).firstChild.toString(),
    XMLNode($xmlNode_.childNodes[4]).firstChild.toString());
}

You can also parse it using XML class, but like I say I prefer to do it this way :)

so with this script we will retrieve all the data from XML file.
This is one way also to get data from DB, create with server side language xml files like this and to parce them. Other options are AMFPHP or ASQL but we will cover these two in future topics.
So the we have to load the XML and get set all data into lets say array object.

So full script goes like:
