Output PHP with PHP?

[Novice@PHP]

I'm trying to output php with PHP.

 

Example.

 

<?php
if ( is_user_logged_in() ) {
    echo '[b]<?php if(function_exists('twit_connect')){twit_connect();} ?>[/b]';
} else {
    echo 'Welcome, visitor!';
};
?>

 

I know I'm way off in what I'm trying to do.

 

What do I need to do?

 

Thanks

 

On a side note Google is fruitless as usual. Sum1 should design a smart search engines for programmers. It would go down a treat.

Single quotes need to be escaped when between single quotes or php thinks your ending your string.

 

echo '[b]<?php if(function_exists(\'twit_connect\')){twit_connect();} ?>[/b]';

echo '[b]<?php if(function_exists(\'twit_connect\')){twit_connect();} ?>[/b]';

 

It doesn't create an error now but nothing displays.

 

Any suggestions thanks

You need eval

I think the OP wants to actually output php code. Could well be wrong though...

You need to output "<" instead of "<" since the browser believes any string starting with a "<" is a tag and will try to use it.

 

So use

<?php
echo '[b]<?php if(function_exists(\'twit_connect\')){twit_connect();} ?>[/b]';
?>

 

or

<?php
echo htmlentities("[b]<?php if(function_exists('twit_connect')){twit_connect();} ?>[/b]",ENT_QUOTES);
?>

Following his logic it made me believe otherwise. I find it weird why he does not just do twit_connect(); as he clearly wants to show the twitter connect login.

Oh I just picked the first piece of code I had pasted in my notepad. Need to dsipplay the google friend connect which doesn't disappear when logged in.

 

Thanks every1 for your advice.

 

I'm off to try the new suggestions.

Tried suggestions and now it just outputs the code as plain text.

 

Any ideas?

 

Thanks

What do you want to do? Your original explanation wasn't clear.

I want to echo the php code for execution.

 

So when it echos it executes the PHP based on the condition if user is logged in.

 

Thanks

All you have to do is put the PHP code in the "if" block:

<?php
if ( is_user_logged_in() ) {
    if(function_exists('twit_connect')){twit_connect()};
} else {
    echo 'Welcome, visitor!';
}
?>

Wow. That makes much more sense. Should have thought about that one.

 

Hopefully this post ranks in the Google beast so others can benefit from it too. 

 

Thank you thank you thank you.

Just because you are incompetent at Google, does not mean they need to make a "smarter" engine. What you really mean is they need to make a "dumbed" down version for people who do not understand how to search for what they want.

 

As for what you are trying to do, I have no clue, your first statement says you just want to "echo" php to the page. Which has been shown to you. But now you say, when it echo's I want it to execute. Is this by change what you are wanting to do (Given that I have no clue what that twit_connect function does or returns this could be wrong as it is just guess work):
