Question

I am manually storing the below line in mysql database using php myadmin.

<div>IP address : '<?php echo $_SERVER['REMOTE_ADDR']?>'</div>

It gets updated as I have confirmed it is in database.
My php page fetches this from database and updates the html.

The output that I get is –
IP address :

I am not an expert in php. Also I cannot write <?php echo $_SERVER[‘REMOTE_ADDR’]?> directly into my php page. Please help and tell me where is wrong.

Answer 1

When you fetch the text from the DB and output it to the client, it will just be WRITTEN, not EXECUTED – so

$_SERVER['REMOTE_ADDR']

will never be replaced by the real IP adsress.

A solution would be to store

<div>IP address : '%s'</div> 

in your DB, later fetch it and

echo sprintf($txtfromdb,$_SERVER['REMOTE_ADDR'])

to your client.
