[Mapserver-users] mode=map with PHP/Mapscript

[William A. Bronsema, C.E.T.]

John,

You can output the map image directly to stdout by using the saveImage() 
function call on a map image object.

In order to call this directly from an image tag I typically call a php 
page dedicated to drawing the map image and returning it to stdout.

For example:

Create a page (called drawmap.php or whatever you like) to draw the map:

<?php

....open mapfile etc.

// draw the map
$oImage = $oMap->draw();

// set the page header
header("Content-type: image/png");

// output the image to stdout (using mapscript 4.0)
$url = $oImage->saveImage("");
?>

Then in my main page call the following image tag:
<img src="./drawmap.php" width=400 height=300>


That should do it for you.  Note: the saveImage function call requires 
parameters to be passed for Mapscript 3.6 
(http://mapserver.gis.umn.edu/doc36/phpmapscript-class-guide.html#ImageObj 
for reference).

Regards,
Bill
