在PHP数组部分匹配比较两个字符串子键值 [英] compare string to sub key value in php array partial match

问题描述

我需要一个方式串弄明白部分匹配到我的PHP数组中的子键。

I need to figure out a way to partial match a string to a sub key in my PHP array.

例如：

字符串=你好，杜迪节目，你可以看到有一个 - 破折号和词之间有一个空格。在我的PHP数组的子键可能是你好杜迪秀没有破折号或它可能是你好杜迪秀与在字符串中有不同的定义之间的冲刺。

string = howdy-doody show as you can see there is a - dash and a space between the words. In my PHP array the sub key might be howdy doody show with no dashes or it might be howdy doody-show with the dash between a different word in the string.

我如何才能找到与字符串数组中的子键给定？

How can I find the sub key in the array with the string given?

样品阵列

$pages = array(

'Administrator' => array(
    'network-administrator' => array('title' => 'Network '.$li_1, 'description' => 'Network '.$li_1.' '.$temp_content, 'post' => '<p>Network '.$li_1.' '.$temp_content.'.</p>'),
    'database administrator' => array('title' => 'Database '.$li_1, 'description' => 'Database '.$li_1.' '.$temp_content, 'post' => '<p>Database '.$li_1.' '.$temp_content.'.</p>'),
),

'Analyst' => array(
    'business systems analyst' => array('title' => 'Business Systems '.$li_2, 'description' => 'Business Systems '.$li_2.' '.$temp_content, 'post' => '<p>Business Systems '.$li_2.' '.$temp_content.'.</p>'),
    'data-analyst' => array('title' => 'Data '.$li_2, 'description' => 'Data '.$li_2.' '.$temp_content, 'post' => '<p>Data '.$li_2.' '.$temp_content.'.</p>'),
),

);

样本串

network administrator

样品变量定位数组值

sample variable to locate the array value

$content = $pages['Administrator']['network administrator'];

与上面的变量，因为该子键使用它不会找到数组中的子键 - 破折号像这样网​​络管理员。

所以，我怎么会得到包括原子项中的数组值，并使用具有空间，而不是像这样短跑字符串，返回其内容网​​络管理员？

So how would I get the array value including the original subkey and returns its contents using the string that has the space instead of dash like so, network administrator?

推荐答案

下面是做到这一点的一种方法：重新映射原来的键包含剥离键一个新的数组，并存储在数组中值的原始密钥

Here's one way to do it: remap your original keys to a new array containing stripped keys, and store the original key in the value for the array.

$t_keys = array();

foreach ($pages as $k => $arr2) {
    foreach (array_keys($arr2) as $a) {
        // perform whatever transformations you want on the key here
        $new_key = str_replace("-", " ", $a);
        // use the transformed string as the array key;
        // we still need to access the data in the original array, so store the outer
        // array key ("Administrator", "Analyst", etc.) and the inner array key
        // ("network-administrator", etc.) in a subarray.
        $t_keys[$new_key] = array( $k, $a );
    }
}

这是一个例子键值对 $ t_keys ：

$t_keys['network administrator'] = ['Administrator', 'network-administrator']

要在原来的访问数组中的价值，我们需要获得 $页['管理员'] ['网络管理员'] ，或者使用等效值从 $ t_keys ： $页[$ t_keys [网络管理员] [0] [$ t_keys [网络管理员] [1] ] 。

To access the value in the original array, we need to get $pages['Administrator']['network-administrator'], or, using the equivalent values from $t_keys: $pages[ $t_keys['network administrator'][0] ][ $t_keys['network administrator'][1] ].

要匹配搜索字符串：

$str = str_replace("-", " ", $original_search_string_from_url);

// check if it's in the transformed keys array
if (array_key_exists($str, $t_keys)) {
    // now we can access the data from our $pages array!
    $target = $pages[ $t_keys[$str][0] ][ $t_keys[$str][1] ];
    echo "the proper name for $str is " . $t_keys[$str][1] . "\n";
//  output: "the proper name for network administrator is network-administrator"

    // access various attributes of the network-administrator:
    echo "the title of $str is " . $target['title'];
}

如果你不需要知道在 $页键的（例如，管理员和网络管理员），只是想获得直相关数据显示，您可以创建引用，而不是存储键。这里有一个例子：

If you don't need to know what the keys in $pages are (e.g. 'Administrator' and 'network-administrator') and just want to get straight to the relevant data, you could create references instead of storing the keys. Here's an example:

$refs = array();

foreach ($pages as $k => $arr2) {
    foreach (array_keys($arr2) as $a) {
        // perform whatever transformations you want on the key here
        $new_key = str_replace("-", " ", $a);
        // create a reference ( =& ) to the contents of $pages[$k][$a]
        // $refs[$new_key] points directly at $pages[$k][$a]
        $refs[$new_key] =& $pages[$k][$a];
    }
}

现在 $裁判['网络管理员'] 就像一个快捷方式 $页[管理员] [网络管理员] ; $裁判[网络管理员] ['后'] 访问 $页[管理员] [网络管理员] [后'] ，等等。

Now $refs['network administrator'] acts like a shortcut to $pages['Administrator']['network-administrator']; $refs['network administrator']['post'] accesses $pages['Administrator']['network-administrator']['post'], and so on.
