Running a Script via Apache
This time we will arrange for Apache to run the script. Let us adapt the previous script to print a formatted list of people matching the name “Anne.” This version is called .../cgi-bin/script_html.
#! /usr/local/bin/perl -wT
use strict;
use DBI();
my ($ref,$mesg,$dbm,$query,$xname,$sname,$sth,$rows);
#print HTTP header
print "content-type: text/html\n\n";
# open a database
$dbm=DBI->connect("DBI:mysql:database=people;host=localhost",'webserv')
or die "didn't connect to people";
# get it back
$xname="Anne";
$query=qq(select xname, sname from people where xname like "%$xname%");
$sth=$dbm->prepare($query) or die "failed to prepare $query: $!";
# $! is the Perl variable for the current system error message
