EXAMPLES
Example #1
get_headers(3) example
<?php
$url = 'http://www.example.com';
print_r(get_headers($url));
print_r(get_headers($url, 1));
?>
The above example will output something similar to:
Array
(
[0] => HTTP/1.1 200 OK
[1] => Date: Sat, 29 May 2004 12:28:13 GMT
[2] => Server: Apache/1.3.27 (Unix) (Red-Hat/Linux)
[3] => Last-Modified: Wed, 08 Jan 2003 23:11:55 GMT
[4] => ETag: "3f80f-1b6-3e1cb03b"
[5] => Accept-Ranges: bytes
[6] => Content-Length: 438
[7] => Connection: close
[8] => Content-Type: text/html
)
Array
(
[0] => HTTP/1.1 200 OK
[Date] => Sat, 29 May 2004 12:28:14 GMT
[Server] => Apache/1.3.27 (Unix) (Red-Hat/Linux)
[Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT
[ETag] => "3f80f-1b6-3e1cb03b"
[Accept-Ranges] => bytes
[Content-Length] => 438
[Connection] => close
[Content-Type] => text/html
)
Example #2
get_headers(3) using HEAD example
<?php
// By default get_headers uses a GET request to fetch the headers. If you
// want to send a HEAD request instead, you can do so using a stream context:
stream_context_set_default(
array(
'http' => array(
'method' => 'HEAD'
)
)
);
$headers = get_headers('http://example.com');
?>

Arch::Log - class representing Arch patch-log
SYNOPSIS
use Arch::Log;
my $log = Arch::Log->new($rfc2822_message_string);
printf "Patch log date: %s
", $log->header('standard_date');
print $log->dump;
my $first_new_file = $log->get_headers->{new_files}->[0];
DESCRIPTION
This class represents the patch-log concept in Arch and provides some useful methods.
METHODS
The following class methods are available:
get_message, get_headers, header, get_changes, split_version, get_version, get_revision, get_revision_kind, get_revision_desc, dump.
get_message
Return the original message with that the object was constructed.
get_headers
Return the hashref of all headers including body, see also "header" method.
header name
header name [new_value]
Get or set the named header. The special name 'body' represents the message body (the text following the headers).
body [new_value]
existing_header_name [new_value]
This is just a shortcut for "header"('method'). However unlike "header"('method'), method fails instead of returning undef if the log
does not have the given header name.
get_changes
Return a list of changes in the corresponding changeset.
ATTENTION! Patch logs do not distinguish metadata (ie permission) changes from ordinary content changes. Permission changes will be
represented with a change type of 'M'. This is different from Arch::Changeset::get_changes and Arch::Tree::get_changes.
split_version
Return a list of 2 strings: full version and patch-level.
get_version
Return the full version name, not unlike split_version.
get_revision
Return the full revision name. This is currently a concatination of headers Archive and Revision with '/' separator.
get_revision_kind
Return one of the strings 'tag', 'import' or 'cset' depending on the revision kind this log represents.
get_revision_desc
Return revision description hashref with the keys: name, version, summary, creator, email, date, kind.
dump
Returns the object dump using Data::Dumper.
BUGS
Awaiting for your reports.
