[SOLVED] request for help writing $_SERVER["REMOTE_ADDR"] as part of an fwrite

[marionreview]

Hi- New to the forum.  Please pardon mistakes.

 

I have a form that creates the variables r1, r2, r3 as part of a very simple HTML form.  The form then calls a php page that does the following:

 

<?php

$myfile = fopen ("outcomes_survey.csv", "a");

$fp = fwrite($myfile,date("Y/m/d").",$_SERVER["REMOTE_ADDR"],$_POST[r1],$_POST[r2],$_POST[r3]

");

fclose($myfile);

?>

 

If I take out the code

 

,$_SERVER["REMOTE_ADDR"]

 

the code works perfectly and write the date and variables to outcomes_survey.csv

 

Can anyone tell me how to fix my code so that it will write the user's IP address?  I assume I have a simple syntax error.  I have tried using single quotes. 

 

Thanks a lot.

When using arrays in strings who's indexes are also surrounded by quotes you must use curly braces ({ }) to tell PHP where the variable starts and ends.

 

$fp = fwrite($myfile,date("Y/m/d").",{$_SERVER["REMOTE_ADDR"]},$_POST[r1],$_POST[r2],$_POST[r3]
");

 

In the future you should use [code] or [php] tags, it makes things easier to read.

and in php6 {} will be the [] square braces i think?

I'm not quite sure about that, perhaps you're referring to the fact that in PHP6 to access specific characters in strings you'll have to use [ ] vs { }.

Thank you AlexWD!  The suggested code worked!  I will include the suggested tags in the future.

Yes i was alex, i was thinking that all {} braces, will become [] square braces in php6

I'm pretty sure that rule only applies to string indexes.
