I've constructed a fairly long list of terms formatted as:

Code:

Target , Replace
Target , Replace
Target , Replace
.
.
.

What would be the most efficient way to replace all instances of Target with Replace within the entire body of a document?

Open it in a text editor with search and replace capabilities

That would work if the document were static but I'm talking about the content of a .php page. The content is being pulled from a database and I'm trying to write a function that reads in words from a list and replaces all instances of those words with a corresponding replacement word. So if my word list contains:

Code:

foo , bar
internet , interweb
webmaster-talk , wmt

and the document at one point in type contains the text:

Code:

I use the internet to visit webmaster-talk.... foo

This should be converted to

Code:

I use the interweb to visit wmt... bar

The list is several hundred lines long so I was curious as to the most efficient way to accomplish this in javascript.

PHP would be the answer NOT javascript

PHP Code:


			
$oldwords = array("foo","internet","webmaster-talk");
$newwords = array("bar","interweb","wmt");

$outstring = str_replace($oldwords,$newwords,$instring);
