Search and Replace

pchastie

I am looking for a script or something that will search a page and replace all instances of a word with either code or another word.

For instance:

If a dynamic page is loaded isit replaces all instances of one word with either a specified word or code.

ie everytime the word "car" is shown it replaces it with <b>car</b> in the code.

Is there a script for this???

Hi,
what do u really mean by dynamic page. Is the contents of the webpage is cooming from a database????
if the data is comming froma a database just simply use the str_replace() function to replace the text u want.
Here a little example,

$str="This is a red car"; // You can use this variable to hold the batabase value

$bodytag = str_replace ("car", "<b>car</b>", $str);

print $bodytag;

output will be,
This is a red car

You can find more information about the str_replace function in,
http://www.php.net/manual/en/function.str-replace.php

Will this replace all instances of this word on a page?

Say that the word "car" is mentioned 8 times on the page? Will it replace all instances of that word or just the first instance?

You dont know the answer, yet you are in a position to test, so test to find out yourself.

I did test is and it didn't work. Any suggestions or Dare I ask.

From the PHP Manual:
"str_replace -- Replace all occurrences of the search string with the replacement string" (emphasis mine)

That implies that somehow, your test wasnt implemented properly.

Can someone give me an example of code on how to use this? I am looking for something that will replace every instance of the word Food. Can someone show me where to place it in the code? Does is go at the start? end? or what?

Food is good. Food is fun. Food fills me up.
