Splitting a variable which contains '.' as the delimiter

[thanawala27]

Hi,

I would like to seperate a variable which has '.' (dot) as the delimiter using the split function.

$var1 = "first.second";
 
@value = split(/./, $var1);

then the value of $value[0] should be "first" and $value[1] should be "second".

but this doesnt happen. it works fine with ',' (comma) as the delimiter but doesnt work with a dot.

can someone guide me here?

any help is appreciated.


Thank You,

Ravi

You need to escape the dot with \. If there are elements already in the array then use push to add the elements to the array.

my @array;
my $var = 'Hello.World';
 
push(@array, split(/\./, $var)); 
 
print $array[0];
print $array[1];

Just to add to what Kevin said about escaping the '.', the reason you have to escape it is because in regular expressions (which is what is between the / and / when using split), the dot has the special meaning of "any single character". So, you have to remove that meaning and make it a character itself by escaping it.
