replacing a string in a file

tombell

Hi,

I want to open a file, search for a string and replace it with another one.

The code I have written though, deletes everything from the file and writes nothing.

Any help?

code:

$handle = fopen("data.txt",'w');

$content = fread($handle, filesize("data.txt"));

$out = str_replace("test","found",$content);

$go = fwrite($handle,$out,filesize($out));

fclose($handle);

There's a bunch of errors in your code.

try this.

$text = join('', file('data.txt'));

$text = str_replace("test", "found", $text);

$file = fopen('data.txt', 'w');
fwrite($file, $text);
fclose($file);

first add a fileexists() test before doing anything to a file.
second display the content of $content before the replace and after and have a look at it...
then tell us if there was something in the file or if you actually found the file...

Igel thanks for the help.
Your script worked.

As for the other reply: "Try a cold shower to relief the tension".

tried the cold shower but it didn't work and you're not suppose to answer the signatures. It's just there to make you tolerantly smile.

You should try and be tolerant with someone with less experience than you in PHP.

I believe you were a newbie at some time

I still am a n00b at soooo many things 🙂 if I spend time in here it is jut to try to help the people who chose the same technology that's been giving me so much fun... PHP.

If I offended you in anyway I apologize.

Happy coding

I appreciate your response and I too apologize.
Anyway I hope you can help me next time I post.
Cheers
