Good job making it through that one! Now let's take a look at some practical examples.

Personalize a message:

string_out = searchandreplace('Hello $$$NAME$$$! Welcome to my web page!', '$$$NAME$$$', 'Tom');

The variable string_out now equals "Hello Tom! Welcome to my web page!".

Format web links:

string_out = searchandreplace('http://www.k2w.f2s.com/', 'http://', '');
if (string_out.lastIndexOf('/') == string_out.length-1){
string_out = searchandreplace(string_out, '/', '', 1, true); }

The variable string_out now equals "www.k2w.f2s.com".

Provide emphasis:

string_out = searchandreplace('Your answer was correct.', 'correct', 'correct');

The variable string_out now equals "Your answer was correct.". This is pretty cool if you have the HTML option set for the Textfield.

Remove newline characters:

string_out = searchandreplace(uploaded_text, newline, '');

If you are uploading text from an external source, you may need to play around with the search string: newline, "\n", "\r", or even "\r\n".

Prepare to send variables:

string_out = searchandreplace('some text to send elsewhere', ' ', '+');

The variable string_out now equals "some+text+to+send+elsewhere".

Change punctuation:

string_out = searchandreplace('I once liked you. But now I love you.', '.', '!', 1, true);

The variable string_out now equals "I once liked you. But now I love you!".

Change case:

for(i=65;i<=90;i++) {
   string_out = searchandreplace(string_out, String.fromCharCode(i), String.fromCharCode(i+32));

This useless example does exactly the same thing as String.toLowerCase(), only the above example is much slower.

Change verb tense:

string_out = searchandreplace('He is a big man.', 'is', 'was');

The variable string_out now equals "He was a big man.".

I'm sure you can think of numerous other uses for this function.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
