Replace

How would I go about making a Replace function in CGI/Perl?

If I wanted to replace all the j's in a variable with p's, how could I do it?

This might be helpful I dont know :)

Use Regular Expressions, one of the greating things in Perl and imitated by many other languages.

So I would do something like:

Code:

---

$string = "The dog is a flick rat-tat-tat."
$string =~ tr/a/ae/;

---

To get "The dog is ae flick raet-taet-taet" ??

(This isn't the exact thing I'm doing, just an example)

Code:

---

$string = "The dog is a flick rat-tat-tat.";
$string =~ s/a/ae/;
print "$string\n";

---

tr is another function, not a RegExp.

Alright, that works, but when I try to do something like this:

Code:

---

$string = "My Name is Bill (William)";
$string =~ s/(/ ( /;
print "$string\n";

---

But it craps out on me? :confused:

( and ) have special meaning - escape them like this:

Code:

---

$string =~ s/\(/ \( /;

ah, I should have known that.

Thanks for all this help, Josh! It would have taken me forever to figure all this out on my own. Thanks again. :)
