); 

foreach($a as $k => $v){ 
    $abc = preg_match_all('/http\:\/\/exmpale\.com\/abc\/(.*?)\.html/',$v,$b); 
    print_r($b[1]); 
} 

und ich möchte das Ergebnis erhalten.

$result = array(
    'http://exmpale.com/abc/exmpale.html', 
    'http://exmpale.com/abc/exmpale1.html', 
    'http://exmpale.com/abc/exmpale2.html'); 

aber es dauerte alles Ergebnis, bitte hilf mir dankt Ihnen.

Answer 1

Verwenden Sie einfach die PHP-Funktion preg_match_all, und die übereinstimmende Zeichenfolge wird in ein Array geladen, das Sie der obigen Funktion als Argument übergeben. Bitte lesen Sie das PHP-Handbuch auf preg_match_all und erstellen Sie eine Regex für Ihre Bedürfnisse. Sie können Ihre regex here

Answer 2

testen Da Sie bieten nicht, welche Art von Datenstruktur werden die URLs gespeichert, gehe ich davon aus, es ist eine rohe string:

$data_raw = "http://exmpale.com/abc/exmpale.html 
http://exmpale.com/abc/exmpale1.html 
http://exmpale.com/abc/exmpale2.html 
http://exmpale.com/abc/exmpale/exmpale1.html 
http://exmpale.com/abc/exmpale/exmpale2.html 
http://exmpale.com/abc/exmpale/exmpale3.html 
http://exmpale.com/abcd/exmpale1.html 
http://exmpale.com/abcd/exmpale2.html 
http://exmpale.com/abcd/exmpale2.html 
http://exmpale.com/abcd/exmpale4.html 
http://exmpale.com/abc/abc/exmpale1.html 
http://exmpale.com/abc/abc/exmpale2.html 
http://exmpale.com/abc/abc/exmpale3.html 
http://exmpale.com/abc/abc/exmpale4.html 
http://exmpale.com/abc/abc/exmpale5.html"; 

$urls = explode("\n", $data_raw); 

$accept_host = "exmpale.com"; 
$accept_path = "/abc/"; 

$filtered_urls = array_filter($urls, function($url) use($accept_host, $accept_path) { 
    $parts = parse_url($url); 
    return $parts['host'] == $accept_host 
     && strpos($parts['path'], $accept_path) === 0 
     && strpos($parts['path'], '/', strlen($accept_path)) === false; 
}); 

printf("<pre>%s</pre>", print_r($filtered_urls, true)); 

Ausbeuten:

Array 
(
    [0] => http://exmpale.com/abc/exmpale.html 
    [1] => http://exmpale.com/abc/exmpale1.html 
    [2] => http://exmpale.com/abc/exmpale2.html 
)
