I have a url formatted like this:
http://www.example.com/detail/state-1/county-2/street-3
What I'd like to do is parse out the values for state (1), county (2), and street (3). I could do this using a combination of substr(), strpos(), and a loop. But I think using a regex would be faster however I'm not sure what my regex would be.
$pieces = parse_url($input_url);
$path = trim($pieces['path'], '/');
$segments = explode('/', $path);
foreach($segments as $segment) {
$keyval = explode('-', $segment);
if(count($keyval) == 2) {
$key_to_val[$keyval[0]] = $keyval[1];
}
}
/*
$key_to_val: Array (
[state] => 1,
[county] => 2,
[street] => 3
)
*/
Could just do this:
<?php
$url = "http://www.example.com/detail/state-1/county-2/street-3";
list( , $state, $country, $street) = explode('/', parse_url($url, PHP_URL_PATH));
?>
if (preg_match_all('#([a-z0-9_]*)-(\\d+)#i', $url, $matches, PREG_SET_ORDER)) {
$matches = array(
array(
'state-1',
'state',
'1',
),
array(
'county-2',
'county',
'2',
),
array(
'street-3',
'street',
'3',
)
);
}
Note, that's the structure of the $matches array (what it would look like if you var_dump'd it...
This regex pattern should work:
$subject = 'http://www.example.com/detail/state-1/county-2/street-3';
$pattern = 'state-(\\d+)/county-(\\d+)/street-(\\d+)';
preg_match($pattern, $subject, $matches);
// matches[1],[2],[3] now stores (the values) 1,2,3 (respectively)
print_r($matches);
matches[1], [2], [3] now stores 1,2,3? Remember [0] is always the full pattern match...
