Hi NG.
I'm having trouble searching through a file and swapping specific phrases
with other phrases.
I'm opening a html-file and i wish to replace "index2.php?someVar=SomeValue"
with somthing else but I can't get this to work properly.
first i open the html file and read all it's contents into a var... let's
call that one $file_contents for this example.
I'm currently trying using:
$altered_file_contents =
eregi_replace("index2.php?someVar=SomeValue","somevar_somevalue.html",
$file_contents);
Then I delete the file i opened, create a new one with the same name and
write the $altered_file_contents into it and close it.
But when I open it and check the line numbers that should have been altered,
they haven't been toutched at all, they still show the first link.
What am I doing wrong?
Why aren't eregi_replace() doing what I think it should?
Please help...

Hi
I, for one, have never done this, but if you are working with html
files, I suppose you open it with your browser ?
Have you cleared the cache, or at least forced the browser to
re-open the file ?
If you edit the file after the change using a text editor, do you
see the changes, or not ?

Hi,
It's none of that.
I suspect that the problem lies with the "?" question mar and the
full-stop. If you look up what the question mark and full-stop means in
an expression, you will find the answer to your problem. Basically you
need to escape the question mark, so it is not evaluated as part of the
expression, but as an absolute value.
So, it should be as follows:
$altered_file_contents =
eregi_replace("index2\.php\?someVar\=SomeValue","somevar_somevalue.html",
$file_contents);
Also, this will only work if the whole of the string is on one line, if
the HTML code is wrapped onto two lines, then you have a problem.
Obviously, there are workarounds, but for now try the above.
You may also want to look at preg_ as this is a more efficient mehtod of
regexp's.

Kevin Smith

why are you using regexp-functions anyway? there's /absolutely/ no need
for them in your case. I can only see disadvantages:
1 - they use more memory than str_replace
2 - they're slower than str_replace
3 - they're more complicated than str_replace
Simply use str_replace, and it'll work just fine; use a regexp and
you'll need to escape characters and other weird things like that.

FYI
This script
<?php
$body = "Test string xpto replace";
echo $body . "<br>";
$body = eregi_replace("xpto", "before", $body);
echo $body . "<br>";
?>
works and produces this output
Test string xpto replace
Test string before replace

DOH! Thanks Kevin for pointing out what should be the obvious !!! /hides
Ofcause, str_replace() I totally forgot about that one, maybe because I've
just been using eregi_replace() a lot lately, I dunno.
Anyway, everything works now as I should, thanks :o)
