Here is the format for using the split function in PERL. Formatting is very important to ensure the function works properly. (Feel free to copy and paste this to a notepad, save the file as a .pl file, and then run it from your command prompt)
#First we define a string
$mystring = "This is my wonderful string";
#Next we incorporate the split function to divide the string at each space
#We have five words, so we'll create 5 new variables
($v1,$v2,$v3,$v4,$v5) = split(/ /,$mystring);
#Now we print our code to check our results (the "/n" creates a new line)
print "$v1\n"
print "$v2\n"
print "$v3\n"
print "$v4\n"
print "$v5\n"
Here's what's happening:
In our first line, we have set a string variable.
In the second line, we create 5 new variables ($v1-$v5) and set these equal to each word split from our string. We do this between the "//" characters. Since we want the split function to split the data at each space, we place a space between the "//" characters.
I found this very useful video of how to do it on youtube:
