捕捉圆括号

Question

$url = '/article/math/unit2/chapter3/para4'; 
$pattern = "\/article"; 

preg_match_all('/^'.$pattern.'(?:\/([^\/]+))+$/', $url, $matches); 

print_r($matches); 

输出是

Array 
(
    [0] => Array 
     (
      [0] => /article/math/unit2/chapter3/para4 
     ) 

    [1] => Array 
     (
      [0] => para4 
     ) 
) 

其实，我想下面给出获取数组。

Array 
(
    [0] => math, 
    [1] => unit2, 
    [2] => chapter3, 
    [3] => para4 
) 

这段代码有什么问题？

UPDATE2：$模式是动态模式。可以改变为“/条/ foo”的，“/条/富/栏”等

Answer 1

您可以简单地使用explode()

参考：http://php.net/manual/en/function.explode.php

<?php 
    $url = '/article/math/unit2/chapter3/para4'; 

    $arr = explode("/", str_replace('/article/', '', $url)); 
    print_r($arr); 

?> 

上面的代码将输出，

Array 
(
    [0] => math 
    [1] => unit2 
    [2] => chapter3 
    [3] => para4 
) 

Answer 2

的问题是，对于每个匹配，它将覆盖为匹配

的输出。在这种情况下，我相信，一个简单的爆炸会多出一个的preg_match更有用

编辑：http://php.net/manual/en/function.explode.php

$url = '/article/math/unit2/chapter3/para4'; 
$args = explode('/', $url); 
// since you don't want the first two outputs, heres some cleanup 
array_splice($args, 0, 2); 

Answer 3

你可以使用PHP爆炸[参考：http://php.net/manual/en/function.explode.php]

$url = '/article/math/unit2/chapter3/para4'; 
$data = explode("/", $url); 

/是你的情况的分隔符

Answer 4

也许你应该尝试用explode()代替？

$url = '/article/math/unit2/chapter3/para4'; 
$matches = explode('/', $url); 
$matches = array_slice($matches, 2); // drop the first 2 elements of the array - "" and "article" 

print_r($matches); 

Answer 5

使用explode()

$url = '/article/math/unit2/chapter3/para4'; 
$arrz = explode("/", $url); 
print_r($arrz); 

Answer 6

$url = '/article/math/unit2/chapter3/para4'; 
$url=str_replace('/article/','','/article/math/unit2/chapter3/para4'); 
print_r(explode('/','/article/math/unit2/chapter3/para4')); 

Answer 7

检查这个鳕鱼，因为它是你输出想要的,

<?php 

$url = '/article/math/unit2/chapter3/para4'; 

$newurl = str_replace('/',',',$url); 

$myarr = explode(',', $newurl); 

$i = 0; 
$c = count($myarr); 

foreach ($myarr as $key => $val) { 
    if ($i++ < $c - 1) { 
     $myarr[$key] .= ','; 
    } 
} 
$myarr = array_slice($myarr,2); 
print_r($myarr); 

输出 -

Array 
(
    [0] => math, 
    [1] => unit2, 
    [2] => chapter3, 
    [3] => para4 
)
