writing $variables to txt files

[Anon]

i want to put this line in a txt file

$$var=$row["$var"];

i know how i can add data to a txt file, that is no problem, but i have a problem with the $row, how the @!#$ can i write that to a txt file ?
if i use

$file_write2 = fwrite($file_open2, "\n<?$$linkname=$row['$linkname'];?>");

i have the following error :

Parse error: parse error, expecting T_STRING' orT_VARIABLE' or `T_NUM_STRING' in F:\FtpRoot\Music-Empire\add_subsite2.php on line 25

There are probably other ways, but I know that this intermediate step would work.
Try writing your intended output to a string
using sprintf(), it works like it's C/C++ counterpart then you can echo/print it and write it to the file...

PHP code inside double quotes is expanded,
So you have to think about which variables you want to print as characters and which variables you want to print just the value of.

use single quotes to print the actual text:

$a='hello';

echo "$a"; // prints hello
echo '$a'; // prints $a

I did it like this :

$file_write2 = fwrite($file_open2, "\n$$linkname=");
$file_write3 = fwrite($file_open2, '$row');
$file_write4 = fwrite($file_open2, "['$linkname'];");

and it works!

tnx 4 your help guys!
