finding out the number of splits

[veteq]

I am using the split function to load an array,
some of the records will split in 2 others only once

if it splits in 2 I need to only keep the 2 record but if it splits once, I keep the 1st record. The problem that I ran into is when the second element [1] in the array is empty, I get an error, is there a way of me knowing the number of times the string was split? this way I only search for element 2 when it splits more than once....

code:
@splitarray = split (/ /,$tmpholder);

Error:
Use of uninitialized value in string ne at Adm4_System_Processes_Restart.pl line 99, <PROCFILE> line 100.


Any help would be greatly appreciated.....I am stuck

You can get the number of elements put into @splitarray by doing the following:

$number = ( @splitarray = split ( / /, $tmpholder ) );

Alternatively, as you always want the last element in the array, just use

my $record = $splitarray[-1];

# or even

my $record = pop(@splitarray);

A couple more ways:

my @array = qw(one two);

# Displays the highest index number used.
print $#array, "\n";

# OR

if (defined($array[1])){
    print "Element 2 is present\n";
} else {
    print "Element 2 is not present\n";
}

You do not even need this @splitarray variable:

$lastField = (split / /, $tmpholder)[-1];
