concat value from array to one string

[edwardsal]

I have array like

@array=("1","2","3");

and how I can make link where I'll have like this:

param1 = (number 1 is $array[0])

$link="param1&param2&param3";

but I dont know how long is array,sometimes is longer?

I'm a bit confused about what you want.

my $link;

for (my $i = 0; $i < @array; $i++ {
   $link .= '&param' . $i + 1 . '=' . $array[$i];
}

print "$link\n";

Alternatively, something as simple as

print join('&', @array);

might be all that is needed.

or...

my ($link,$i);

for(@array){
   $i++;
   $link .= "&param$i=$_";
}

print "$link\n";

Or:

my $link = join '&', map "number $_ is " . $array[ $_ - 1], 1 .. @array;
