Re: [PHP3] returning value from php3 to HTML (src attrib of img tag) From: Jean de Lavarene (breux <email protected>)
Date: 05/12/00

I am not sure this is what you wanna do but here are
my comments :

1. In the trial.html file :

 HTML file: trial.html
 -----------------------
 <html>
 <head>
 <title>trial</title>
 </head>

<body>

 <a href="http://webserver/trial.php3?a=1">
<img src="http://webserver/image.gif">
 </a>

 </body>
 </html>

2. In the trial.php3 file what you can do is:

<?
if ($a!=1) {
    print "<img src=\"orangebox.gif\">";
}
else {
    print "<img src=\"blubox.gif\">";
 }
