calling php from html

Anon

How can I call a PHP script from a HTML page? Like if the URL of the PHP is

http://www.blah.com/file.php3

and my html page is

http://www.me.com/index.html

what do I have to put in the HTML to use the PHP3 page?

Ummm not the question is a little vague, but I'll give it a whack...

So I'm guessing you are either asking how do you link to a php file from an html file or how to run a php file from within an html file, well to link to a php file is exactly the same as any other file <a href="filename.php">text</a> and you can use it to replace an image in an img tag <img src="filename.php">.

But you can NOT run a php file from within an html file because a standard html file doesn't execute in anyway, now you could probably use a little bit of javascript to run some sort of insert text from src file, but I've done this before and it only works with IE and craps out in netscape so it's not really worth the trouble.

I hope I covered your question in one way or another, if I didn't then just try to re-phrase it in more detailed terms and include an example of how you want to use it in an html file then I can give it another try 🙂

It is also possible to force your web server to pass all *.htm(l) files to php for processing. Then you can just include() or require() the php file. However, this can represent a significant performace hit on your web server.

Describe in a bit more detail what you are trying to do and maybe you'll get a better answer.

Let me put it this way, can I exicute a php by calling it from an image tag? Kinda like you can in perl for a counter.

OK, the image tag thing, how can I do that? Like have the script do a few things then display an image for the HTML page.

Yep, as far as the client software (NS, IE, ETC.) is concerned a php script is just a bunch of data, the server executes the script it then sends whatever the script tells it to send. So all you do is tell the client that it's a graphic and BAM it's a graphic, well not quite that simple you still need to get the graphic data from somewhere, but thats easily done with PHP's graphic functions.

Anyways here's a basic example of how to get a php script used in the palace of a graphic.

~~index.html~~
<img src="getimage.php">

~~getimage.php~~
header("Content-type: image/jpeg");
include("image.jpg");

Now I know I kinda cheated there I'm just obraining the data from the file "image.jpg" but for what I was trying to demonstrate it was a whole lot cleaner than trying to show all the createimage functions and junk, there are a whole bunch of tutorials out there, on here on phpbuilder as well, so I didn't think I should get too in depth here.

Anyways hope this helps at least in part.

It does help, thank you very much!
