I have http header string
GET /phpmyadmin/sql.php?db=monitor&table=boundries&token=08b1cd52b3bc0068ea470988e292f54d&pos=0 HTTP/1.1
Host: mylocalwebhost.net
The above is a sample string which I will recieve through a file. In each string I need to check for validity for the first line.
The 'GET' portion can be any of GET PUT POST DELETE.
How can I match the first line using a regular expression. Please some one provide me with a valid regex that I can use with php preg_match()
/^(?:GET|PUT|POST|DELETE) (.*?) \S+$/m
<?php
$re = '/^(?:GET|PUT|POST|DELETE) (.*?) \S+$/m';
$str = 'GET /phpmyadmin/sql.php?db=monitor&table=boundries&token=08b1cd52b3bc0068ea470988e292f54d&pos=0 HTTP/1.1
Host: mylocalwebhost.net';
preg_match($re, $str, $matches);
echo $matches[0];
?: in the above regex?
(.*?) is backreferenced as 1./m means?Multiline which means that ^ and $ match at the start and end of a line respectively.Try with this:
$string = '//phpmyadmin/sql.php?db=monitor&table=boundries&token=08b1cd52b3bc0068ea470988e292f54d&pos=0';
$parts = explode("&", $string);
$parts = array_map("trim", $parts);
foreach($parts as $current)
{
list($key, $value) = explode("=", $current);
$data[$key] = $value;
}
echo '<pre>';
print_r($data);
echo '</pre>';
The result is:
Array
(
[//phpmyadmin/sql.php?db] => monitor
[table] => boundries
[token] => 08b1cd52b3bc0068ea470988e292f54d
[pos] => 0
)
$data['token'];
