How do I place a PHP variable in this link?........

The following Javascript link opens a popup window:

<a href="javascript:MM_openBrWindow('skills/integrated/index.htm','Details','scrollbars=yes,width=660,height=440')">

How would I place a PHP variable within it so it is available on the next page?

 

Where in that javascript would you like the variable to be placed?

 

I'm assuming here that index.htm is a PHP file:

<a href="javascript:MM_openBrWindow('skills/integrated/index.htm?variableName=variableValue','Details','scrollbars=yes,width=660,height=440')">

Code (markup):

Then in PHP:

echo $_GET['variableName'];

Code (markup):

will output:

variableValue
