Open a file, do a search and replace on text within it

[madmax99]

I want to open a file and write to it changes after doing a search and replace on certain text.

this is how I am trying it, but it does not work.
any ideas?

$fp = fopen (&quot;<file_name>&quot;, &quot;r+&quot;
$fputs_str = ereg_replace (&quot;sub_category_id&quot;, &quot;XXX&quot;, &quot;$fp&quot;
fputs($fp, $fputs_str,strlen(100000));

fopen does not return a string containing the contents of the file. It returns an integer which is a handle to the file.

after fopen you should do

$string=fread($fp,filesize(&quot;file.txt&quot);
then use the $string in the ereg.

If you are opening a local file, why are you not using

$contents = @implode('',@file(<file>));
$contents = preg_replace(&quot;/sub_category_id/&quot;, &quot;XXX&quot;, &quot;$fp&quot;

and do what you want with the modified content. ICQ: 54380631

inlandpac,

Just one thing, file is not only for local files. It opens ftp and http calls to. It cannot opens HTTPS.

The advise to use fread instead of file, was by the fact that he needs to open the file, do something than re-write it. That way you can use a fread command. Anikin
