new to PHP, help/advice on turning data into an image

[NeilMac]

Hi, I'm pretty new to PHP, struggled my way through most of my encounters with PHP so far, but getting the hang of it 

 

I'm looking for a simple script that turns a number or word served by a weather station into a graphic. E.g. If the temp is 20 degrees, a graphic I've designed would be shown, or a cloud or the sun or whatever.

 

At the moment the weather station feed is converted from 'webtags' in to php tags (temp is $temp, wind is $wind etc.) and these echo out as numbers and words on the website.

 

I can sort of see how it would work in my head, but need a little help.

 

Can anyone please point me in the right direction?

 

Thanks

Thanks, but I think that is an overly complicated way of doing what I need, rather than adding text to an image I need to to directly replace the text value, e.g. replace the word '1°C' with a pre-designed graphic called '1degreec.gif', I would rather spend more time creating a shed load of separate graphics than use too much PHP.

 

Bearing in mind I would be replacing several values, therefore adapting and running the above mentioned script seems like overkill

so you'd take that $temp variable

and then :

 
<?php
echo '<img src="images/degrees/'.  str_replace(chr(176), '',  $temp). '.jpg" alt="'. $temp. '">';
?>

 

or if it's an html page mostly

 

 

 
<img src="images/degrees/<?php echo str_replace(chr(176), '', $temp). '.jpg" alt="'. $temp; ?> ">

 

and then just have an images/degrees/ folder with 20.jpg, 21.jpg, etc in it. or whatever format you need, just change the extension in the code.

 

 

rereading just do a str_replace, taking out the degree symbol, and then name the images 20C.jpg, etc. i updated the code above to reflect that.
