Word filtering

rapmonkey

How can I make it so every time the word "pizza" shows up in the page, it replaces it with "macaroni"?

altexis

use the str_replace() function

rapmonkey

I tried that but I can't quite get it to work for some reason.

Try using something like this:

preg_replace('pizza','macaroni');

I get this:

Warning: Wrong parameter count for preg_replace()

Oh, I'm sorry, you have to give it something to get the info from.
How and what are you trying to change? Like a user input, body text, or what??

rapmonkey

I'm trying to change anywhere that word is found on the entire page.

If it's not a lot of text, why not just do it by hand? Most web editors have a tool that allows you to search for a word and replace it by another one. Just find all the pizzas and replace them with macaroni. 🙂

Anyways...

$string = "all the pages text in here!";
preg_replace('pizza','macaroni',$string);

Hi, I'm interested in doing almost exactly the same thing. I tried putting the final code into a simple PHP page as such:

<? $string = "all the pizza and macaroni pages text in here!";
preg_replace('pizza','macaroni',$string); ?>

but I get the following error:
Warning: Delimiter must not be alphanumeric or backslash in <...>/TestingFindReplace.php on line 2

Also, instead of [<? $string = "all the...here!";] which requires pasting new text in there each time the page is updated, is there an automated way you could just have it search the whole file? Thanks!

By the way, I'm on PHP 4.3.2, but I don't think there's anywhere for me to put $_POST, etc., here that would fix it, right?

<?php
$string = "I like pizza!";
preg_replace ("/pizza/si", "macaroni", $string);

str_replace ("pizza", "macaroni", $string);

This might work with the whole file thing that bizchris2001 was talking about.

$file = path/to/file.htm
$file2 = fopen("$file", r);
$ex = explode(" ",$file2);
$new = str_replace ("pizza", "macaroni", $ex);

Hope it works,

bizchris2001

Bootsman, neither of those did the trick - they both end up displaying "I like pizza!"...

<?
$string = "I like pizza!";
str_replace ("pizza", "macaroni", $string);
print $string ?>

Batman, I'll try yours next - thanks for the feedback, both of you!

Batman,

No luck - I got an error in line 3 (the url), so I put " " around it and that seemed to be acceptable. However, I still get

Parse error: parse error in <...>indexTEST2.php on line 4

when running the following code:

Plain text
<?
$file = "http://.../indexTEST2.php"
$file2 = fopen("$file", r);
$ex = explode(" ",$file2);
$new = str_replace ("text", "macaroni", $ex); ?>

Note that I'm opening the same page I'm currently using (which may make it tougher or maybe there's a simpler solution thanks to that). I also tried learning more about how to use fopen, and it looked like I had to update it to
$file2 = fopen("$file", "r");
but I still get the error on line 4. Thoughts? Thanks,

Chris

Updated version.
This will not only take pizza, it will also take PIZZA, Pizza, PizzA, and any other combonation you can think of. 🙂

$file = "path/to/file.htm"; 
$file2 = fopen("$file", r); 
$ex = explode(" ",$file2); 
$new = str_ireplace ("pizza", "macaroni", $ex);

bizchris2001

Shoot, thought I had it for a second there. :-P It also looks like in the case of using fopen with variables, no quotes are needed around it - so the line is now:

$file2 = fopen($file, "r");

Fyi in trying to wrassle this error...

batman

This simple little snippet works for me.

<?

$var = "I like pizza";

$new = str_replace ("pizza", "macaroni", $var);

?>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body bgcolor="#FFFFFF" text="#000000">
<?
echo "$new";
?>
</body>
</html>

I'm still working on the other part.  :D

bizchris2001

Woohoo, I think we have a winner! Gonna grab some dinner and then finish trying it out - is it okay if I don't mark Resolved until we see about the second part? This is fun, I'm learning so fast and I really appreciate it! :-) Thanks,

Chris

Okay, sorry to piggyback - but I would absolutely love to be able to resave the page on the server with the text changed. Can you give perspective about how complicated/possible this would, and set me on the starting path? I promise I'll stop asking questions after this. :-P Thanks much!

Chris

Okay, at first glance it did work - but I realized we're back to this:

  "Also, instead of [$string = "all the...here!";] which requires pasting new text in there each time the page is updated, is there an automated way you could just have it search the whole file?"

So I think basically replacing this:

$var = "I like pizza";

with something that says "look throughout the whole file/page, and replace everywhere you see it"

Thanks for your continued assistance!
