[Resolved] str_replace annoyances

venutip

Hey everyone,

Had some problems using str_replace the first time I tried it. Here's what I did:

$contents = str_replace(" ", "", $contents);
echo $contents;

Pretty simple, right? Except that $contents is returned without any modifications having been performed on it.

I modified the code thusly and it worked fine:

$newfile = str_replace(" ", "", $contents);
echo $newfile;

It's just an annoyance, but why should I have to create a new variable, when what I really want to do is modify the original one? 😕

Thanks in advance for your replies !
My apologies if the answer is obvious !

Thats pretty weird can you show us how your using str_replace in the rest of the file. It may have something to do with that because you shouldnt have to create a new variable with str_replace

Hey,

Yeah, no problem. Here's the whole file as of now.

<?php

$file = 'players.txt';
$fp = fopen($file, 'r+');
$contents = fread($fp, filesize($file));

$contents = str_replace(" ", "", $contents);
echo $contents;

?>

players.txt is just a regular TXT file with a bunch of names and ID numbers. Nothing special. Let me know if you need any more info.

As your not writing to the file you should open it with r instead of r+

Other than that I cannot see any problems as I did a similar thing to that except used r.

<?php

$fp = fopen("/home/username/signature","r")or die("Cannot open file for reading");
$contents = fread($fp,filesize("/home/username/signature"));
$contents = str_replace("\n","<br />\n",$contents);
echo $contents;
fclose($fp);

?>

Just modify it to what you need except i Replace \n to make sure the tag is instead of

Hey,

Well, I opened it with plain old 'r' and it worked correctly. Oh well. Guess that's how you have to do it.

Anyway thanks a lot for your help on this one.

Happy holidays !
