Split string into array with various delimiters in PHP [closed]

Question 1

You can try and adapt something like this:

$pattern = '~(?<id>\d++)'                                        . '\s++'
         . '(?<datetime>\d{4}-\d{2}-\d{2}\s++\d{2}:\d{2}:\d{2})' . '\s++"'
         . '(?<useragent>[^"]++)'                                . '"\s++'
         . '(?<ip>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})'           . '\s++'
         . '(?<name>\S++)'                                       . '\s++'
         . '(?<response>[A-Z]++)'                                . '\s++'
         . '(?<country>[A-Z]{2,3})'                              . '\s++'
         . '(?<title>(?>[^h\s]++|\s*+(?>h(?!ttp://))?|\s++)+)'   . '\s++'
         . '(?<url>\S++)'                                        . '\s++'
         . '(?<search>\S++)~';

preg_match_all($pattern, $subject, $matches, PREG_SET_ORDER);

foreach($matches as $match) {
    echo '<br/>id: '         . $match['id']        . '<br/>datetime: ' . $match['datetime']
       . '<br/>user agent: ' . $match['useragent'] . '<br/>ip: '       . $match['ip']
       . '<br/>name: '       . $match['name']      . '<br/>response: ' . $match['response']
       . '<br/>country: '    . $match['country']   . '<br/>title: '    . $match['title']
       . '<br/>url: '        . $match['url']       . '<br/>search: '   . $match['search'] 
       . '<br/>';
}

Notice: you can put all the fields you expect in an array and reduce the size of code.

Question 2

Your problem isn't that you're trying to split a string into an array with various delimiters.

Your problem is that you're trying to do browser detection from the user agent string.

For every programming problem you have, ask yourself "Is this something that others might already have had, and that I might take advantage of their solutions?"

If so, then try Googling for the answer. In this case, I Googled for "php parse user agent". That search led me to this page on StackOverflow which led me to this function that is built in to PHP itself.
