This is what i tried, also i dont want the hosts and explanations which are commented with #/ ##
$str = '# Virtual Hosts
#
# Required modules: mod_log_config
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn\'t need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.4/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option \'-S\' to verify your virtual host
# configuration.
#
# Use name-based virtual hosting.

# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ##ServerName or ##ServerAlias in any <VirtualHost> block.

Any help would be appreciated, coz i'm new to regex..... Also i don't needany of the strings which are commented with #/##, Thanks in advance..
Use as a regex:
'~^\s*<VirtualHost\s+[^>]*>\s*ServerName\s+(?P<ServerName>\S+)\s*DocumentRoot\s+(?P<DocumentRoot>\S+)\s*</VirtualHost>~m'
Then what you need will be in capture groups 1/'ServerName' and 2/'DocumentRoot'.
Explanation:
^ - Match start of line with m flag set.\s* - Match 0 or more whitespace characters.<VirtualHost - Match '<VirtualHost'.\s+ - Match 1 or more whitespace characters.[^>]* Match 0 or more characters that are not '>'.> - Match '>'.\s* - Match 0 or more whitespace characters.ServerName - Match 'ServerName'.\s+ - Match 1 or more whitespace characters,(?P<ServerName>\S+) - Match 1 or more non-whitespace characters as capture group 'ServerName'.\s* - Match 0 or more whitespace characters.DocumentRoot - Match 'DocumentRoot'.\s+ - Match 1 or more whitespace characters,(?P<DocumentRoot>\S+) - Match 1 or more non-whitespace characters as capture group 'DocumentRoot'.\s* - Match 0 or more whitespace characters.</VirtualHost> - Match '</VirtualHost>'.The code:
$regex = '^\s*<VirtualHost\s+[^>]*>\s*ServerName\s+(?P<ServerName>\S+)\s*DocumentRoot\s+(?P<DocumentRoot>\S+)\s*</VirtualHost>~m';
preg_match_all($regex, $str, $matches, PREG_SET_ORDER);
print_r($matches);
Prints:
Array
(
[0] => Array
(
[0] =>
<VirtualHost *:8080>
ServerName CI2
DocumentRoot D:\xampp\htdocs\codeigniter_2\public
</VirtualHost>
[ServerName] => CI2
[1] => CI2
[DocumentRoot] => D:\xampp\htdocs\codeigniter_2\public
[2] => D:\xampp\htdocs\codeigniter_2\public
)
[1] => Array
(
[0] =>
<VirtualHost *:8080>
ServerName CI3
DocumentRoot D:\xampp\htdocs\codeigniter_3\public
</VirtualHost>
[ServerName] => CI3
[1] => CI3
[DocumentRoot] => D:\xampp\htdocs\codeigniter_3\public
[2] => D:\xampp\htdocs\codeigniter_3\public
)
)
Update
The above regex assumes that the DocumentRoot specification contains no embedded spaces, which may not always be the case. It also had an extraneous, unnecessary s*, which I have removed. The following regex, I believe, is an improvent. It replaces \S+, which matches 1 or more non-whitespace characters with .+?, which will non-greedily match 1 or more of any character (except for the newline character). Since it is followed by \s*</VirtualHost>, being non-greedy it will stop matching as soon as it finds '</VirtualHost> optionally preceded by any whitespace.
So the new regex would be (used with the m flag):
^\s*<VirtualHost\s+[^>]*>\s*ServerName\s+(?P<ServerName>\S+)\s*DocumentRoot\s+(?P<DocumentRoot>.+?)\s*</VirtualHost>
$regex = '^\s*<VirtualHost\s+[^>]*>\s*ServerName\s+(?P<ServerName>\S+)\s*DocumentRoot\s+(?P<DocumentRoot>.+?)\s*</VirtualHost>~m';
preg_match_all($regex, $str, $matches, PREG_SET_ORDER);
print_r($matches);
