Need advice, guidance on triggering a .wav file to play when a web page loads content and a specific keyword is within body of that content.
The content is being pulled from a Yammer network thru a custom app I created to look for certain hashtag messages using PHP. Now, I'd like to have a sound play (like a bell) when a specific hashtag has a new message. The bell would not ring a second time, just on the intial display.
Suggestions (using PHP)?
To play music in your site, place, <embed src="yourfile.wav"></embed> anywhere in page and checkout.
You can make it dynamic by using php in src.

Now, I am encountering some difficulties when I have to scan or crawl a video URL link. This web page is using the Flash-based technology to embed the video and stream video.
In order to understand more clearly, this is a link example:
http://vnexpress.net/gl/the-gioi/tu-lieu/2012/11/bai-phat-bieu-thua-nhan-that-bai-cua-romney/
The above link has below content (HTML code for Flash embedded video):
<div id="flashContent" style="text-align:center;width:100%;">
<span id="FlashPlayer79237" class="Normal" align="center">Bạn cần cài Flash Player để xem được Clip này.</span>
</div>
In this above article, there is a above video. However, when I tried to scan or crawl the content, the video could not run properly (because it could not load correct video link) and only show Install Flash Player plugin words (Certainly, the real web page needs to run some Javascript script or Flash script to obtain the real video link and stream this video for users)
Therefore, how can I render Flash and Javascript script through PHP or ASP.NET or Java? How can I get the correct video link when I crawl the web page? In this case, how can I obtain the correct Flash embedded video (HTML code)?
Thank you so much.
Before I answer, I want to make a note that if you need this information to do anything shady... please don't.
Disclaimer aside, for that particular site it is relatively easy.
The flashvars param (which is probably put there by Javascript) contains a value called xmlPath, which is a url encoded path (relative to their domain name). If you grab that and decode it, you get something like:
/Service/FlashVideo/PlayListVideoPage.asp?id=79237&f=108&t=1
which points to
http://vnexpress.net/Service/FlashVideo/PlayListVideoPage.asp?id=79237&f=108&t=1
If you read that, it's an XML file which contains the URL of the actual video.
I'm not quite sure where that value is generated from. If you needed to do this fully server-side, you could use a headless browser to process it.
How could I use imagegrabscreen to get a thumbnail image and a full size image of a specific website.
I was thinking that I could have an array that I feed the wanted uri's into but I am a bit stuck on how I would set the wxh of the image I need to grab. I also think that I would need a thumbnail class and a fullimage class and call them when required.
Any better Ideas?
Keep in mind that imagaegrabscreen is Windows-only. If you have multiple displays set up, this function will only grab the primary display. Also, for this to work, your Apache service must be set to Allow service to interact with desktop otherwise you will just get a blank image.
This discussion covers the use of imagegrabscreen pretty well: Getting imagegrabscreen to work
There are a lot of other discussions about saving webpages as images, too - here are a few:

In any languages, Can I capture a webpage and save it image file? (no install, no activeX)
I'm trying to detect if a page has a video. If it does then display it on the page. I've seen this done with sites like youtube but I need something to pull in more sites like vimeo, blog video sites like tumblr and so on.
Is there a script that just searches for video on a page?
Any help is much appreciated or at least point me in the right direction.
You could do a find on the body using a video embed selector.
(Using JQuery)
$('body').find('embed').css('display','block');
I'm working on a website for a specific client. And he wants to be able to add link to the website, and on mouse hover to have a image of that website appear.
Now, he doesen't want to take an image of the website, he only wants to input the link and have the website do everything else.
So my question is ->
Is there a way (eg. google API) to get a website image only by providing the url via php?
Sort of like in google, when you hover over a lik of a page, a tooltip pops up to the right with an image.
Any help is, as always, appriciated :)
Here is a list of 10 free thumbnail services
http://www.webresourcesdepot.com/10-free-website-thumbnail-generation-services/
You can simply refer to the URLs of these services, e.g.
<img src="http://SnapCasa.com/Get.aspx?code=[code]&size=[size]&url=[url]" />
or make a CURL call from one of your PHP scripts and temporarily store/permanently save the image that was generated.
Have recently developed Thumbnailspro.com. It is currently free to use while in beta testing as we work out the bugs, but so far its getting quite popular, you can request thumbnails directly from your website using the code below :
http://thumbnailspro.com/thumb/http://msn.com&s=150
s=Size, size can be anywhere from 10 to 1000 pixels just add s=300 to display a thumbnail 300 pixels in width. We are trying to add more options as we go for thumbnail requests and at the same time trying to keep it as simple as possible so you don't have to enter something like the code below to get your thumbnails :
http://somethumbnailsite.com/viewurl.php?url=http://msn.com&x=200&y=300&bwidth=1024&bheight=768&rotate=76&what_the_hell%20_is_all_this_crap!
So is much more effecient!
Like the service or have any bugs contact us at admin#thumbnailspro.com!
No. The only way to do this is to request the HTML for the page, render the page and then create a thumbnail from that page render. Google does this because in the process of spidering the web, they already get all that data, and they've got a nice optimized rendering engine (Chrome) that they can put the data through, and then they've got tons of online storage space to store the cached image. There's a lot of work there, though.
My app is posting to users' Facebook walls, and linking to a page they have created. The page is in html. I'd like to be able to put a thumbnail of the page as the image on the wall post. I'm not sure whether this is possible or not. Anyone have any ideas?
If it helps, the page itself is stored as a series of 'elements'... for each one, I know the size and position of the element, and the content (which may be text or an image). So I can pull all that in from the database.
I guess it would be sufficient to create a thumbnail using php at the point when the user clicks 'Publish This to my wall', if that's easier than doing it on the fly - I can save the image and then link to it.
Any ideas?
I create thumbnails for my site using CutyCapt, which works very well indeed on both Windows and Linux. You can use exec to invoke this from php.
There are also web services that allow you a quota of free thumbnail snapshots, that are easy to integrate into your website. e.g.
http://www.websnapr.com/
or
http://webthumb.bluga.net/home
I figured out how to do this. I used the PHP gd library, which allows you to create a base image and then add images and text. Works pretty well.
