[SOLVED] Remove linefeed from php read by conky.

273 · 05-25-2012, 04:23 PM

I am sure this is just my ignorance but I am struggling to find a way around this.
I want to display my external IP in conky so I have it read a page on my website. The problem is that the page has a linefeed I don't want.
The webpage is:

Code:

<?php
echo $_SERVER['REMOTE_ADDR'];
?>

and the conky entry is:

Code:

External IP: ${curl mysite.com/ip/ 60}

I know it's something simple I'm missing but I feel the only way I would correct this is to introduce more complexity when what I need is less.

I think it is the newline after the ?>.

Are you sure you don't have an extra newline (possibly after some whitespace) at the end of the file?

I guess easiest would be to save the PHP file without newlines, for example by saving the PHP file using command

Code:

printf '<?php echo $_SERVER[\047REMOTE_ADDR\047]; ?>' > filename.php

Note that if you edit the file, most editors will add a newline at end for you automatically.

Thank you, it was a stray newline at the end of the PHP file.
I had become too used to ignoring whitespace. Apologies for the laziness of my question but I don't think I would have realised it was due to whitespace in a year of googling.
