Using fopen function....

allworknoplay · 03-19-2009, 01:31 AM

Hey guys...

I am currently using shell_exec to create/add data to about 5 different files. I'd like to get away from shell_exec and use fopen. I'm trying to be a better programmer so what is the best way to use fopen if I need to add data to 5 different files? Do I just simply open/close handle, open/close handle literally 5 times? Or should I create some kind of function for it?

I don't need to read the file.

If the file exists, write to it, if not, create it. If there's data, write over it. That's why I will be using "w".

$fp = fopen("/usr/local/apache/htdocs/dev01.txt","w") or die ("some message");

Here's what I am doing currently...
(don't worry about what it is that I'm doing, it's a LONG story)

Code:

shell_exec("echo \"$dev01\" > /usr/local/apache/htdocs/$dev01.txt");

shell_exec("echo \"$dev02\" > /usr/local/apache/htdocs/$dev02.txt");

shell_exec("echo \"$dev03\" > /usr/local/apache/htdocs/$dev03.txt");

shell_exec("echo \"$dev04\" > /usr/local/apache/htdocs/$dev04.txt");

shell_exec("echo \"$dev05\" > /usr/local/apache/htdocs/$dev05.txt");

So I basically want to replace the above code with fopen function....

Soemthing like this may help

PHP Code:


			
<?php

function WritetoFile($file, $content) {

    $fp = fopen($file, 'w');

    fwrite($fp, $content);

    fclose($fp);

}



$newcontent = 'The new content for myfile.txt';

WritetoFile('myfile.txt', $newcontent);

?>

WritetoFile('myfile.txt', $newcontent);

Thanks Krik, I will give that a shot....

My program is about 1000 lines long. Towards the end is where I use the shell_exec...

It is all procedural, no OOP at all....

So can I create the function on the top of the program and use the WritetoFile() function anywhere in the script?

Yep that will work

Sounds like file_put_contents could help you.

PHP Code:


			
file_put_contents('filename.txt', 'file contents...');

Why create your own function when the language itself provides you with one? I just don't see the point, unless you want to append to an existing file.

Ohhh even better! I didn't know about this function.

Let me look into it....

Ok file_put_contents is EXACTLY what I was looking for.

I apologize about using fopen as i wasn't aware of this function.

But at least now I know how to use fopen with multiple files!!

yea, file_put_contents is one of those great stream wrappers introduced in PHP5. file_get_contents is also very useful.

Yeah, that's what's kind of pathetic of me, I am actually using file_get_contents in my script ironically, and I never thought about file_put_contents!!!

Absolutely true and I'm trying to soak all of it up as much as possible.....
