PHP Variable to javascript

[acmumph]

So I want to pass a php variable to the following line of code:

 

echo '<script type="text/javascript">alert("Registration number already exist");history.back(); </script>';

 

 

I thought I could do this:

 

$regnum="12345";

echo '<script type="text/javascript"> var regnum="<?php echo $regnum; ?>";alert("Registration number:"+regnum+" already exist");history.back(); </script>';

 

 

The alert displays "Registration number:<?php echo regnum;?> already exist"...

 

Appreciate any feedback.

echo '<script type="text/javascript">alert("Registration number: '.$regnum.' already exists");history.back();</script>';

Just concatenate it into the output string like you would any other variable. The fact that it is going into a JS string doesn't really make that much of a difference.

For some reason I couldn't seem to get that right. Something about single and double quotes screw me up....

 

Appreciate the solution..
