[SOLVED] PHP Help: Echo within Echo

[Bricktop]

Hello all,

 

I wonder if you could help me with something, I'm somewhat of an amateur and am not sure if the below is possible but any help would be greatly appreciated.

 

Essentially, I want to incorporate some captcha code that I have working elsewhere in a simple form element into some more complex php code.

 

Basically, I currently have:

 

content .='blah blah';
content .='blah blah';

echo $content

 

However, my captcha code is as follows:

 

<img src='captcha.php?f=<?php echo $f;?>'>

 

$f is declared earlier with the relevant randomisation code.

 

However, if i combine the above into:

 

content .='blah blah';
content .='blah blah';
content .='<img src='captcha.php?f=<?php echo $f;?>'>';

echo $content

 

The captcha image displays but it is always the same image - it does not randomise.  Could anyone point me in the right direction please?

 

Thanks

This should be what you want:

 

content .='blah blah';
content .='blah blah';
content .='<img src=\'captcha.php?f='.$f.'>';
