Php 函数中的数组

所以我有这个函数

function parse_records($html) {
    foreach($html->find('li.vcard') as $vcard):
        $table = array();  
        foreach($vcard->find('span.given-name') as $given_name):                    
            $table['given_name'] = (trim(addslashes($given_name->plaintext), " "));
        endforeach; 
        foreach($vcard->find('span.family-name') as $family_name):
            $table['family_name'] = (trim(addslashes($family_name->plaintext)," "));
        endforeach;
        foreach($vcard->find('span.location') as $location):
            $table['location'] = (trim(addslashes($location->plaintext), " "));
        endforeach;
        foreach($vcard->find('span.industry') as $industry):
            $table['industry'] = (trim(addslashes($industry->plaintext), " "));
        endforeach;
        foreach($vcard->find('dd.current-content') as $headline):
            $table['headline'] = (trim(addslashes($headline->plaintext), " "));
        endforeach;
        foreach($vcard->find('a.btn-primary') as $url):
            $table['url'] = addslashes($url->href);
        endforeach;
        return $table;
    endforeach;

在我的主文件中，我是这样使用它的

$page = curl_request($fn, $ln);
$records = parse_records($page);
print_r($records);

---

但这只是一个记录。我应该修改什么，以便能够传递正在传递的所有记录？。我尝试了

（trim（addslashes（$given_name->plaintext），“”）

，但没有效果。

您需要像这样附加数组：

function parse_records($html) {

    // Array to hold all records
    $table = array();  

    foreach($html->find('li.vcard') as $vcard):

        // New array for each record
        $row = array();

        foreach($vcard->find('span.given-name') as $given_name):                    
            $row['given_name'] = (trim(addslashes($given_name->plaintext), " "));
        endforeach; 
        foreach($vcard->find('span.family-name') as $family_name):
            $row['family_name'] = (trim(addslashes($family_name->plaintext)," "));
        endforeach;
        foreach($vcard->find('span.location') as $location):
            $row['location'] = (trim(addslashes($location->plaintext), " "));
        endforeach;
        foreach($vcard->find('span.industry') as $industry):
            $row['industry'] = (trim(addslashes($industry->plaintext), " "));
        endforeach;
        foreach($vcard->find('dd.current-content') as $headline):
            $row['headline'] = (trim(addslashes($headline->plaintext), " "));
        endforeach;
        foreach($vcard->find('a.btn-primary') as $url):
            $row['url'] = addslashes($url->href);
        endforeach;

        // Add row to table
        $table[] = $row;

    endforeach;

    // wait till the end to return the whole thing
    return $table;
}

function parse_records($html)
{
    $tablesList = array();

    foreach($html->find("li.vcard") as $vcard)
    {
        $table = array();

        // Add keys to the table like you are doing.

        $tablesList[] = $table; // Add this table to the tables list.
    }

    // Return the list of all of the tables we produced.

    return $tablesList;
}

关键行是每个

vcard

foreach创建一个名为$row的数组，然后在循环结束时，我们将整行添加到表中，

$table[]=$row

它只返回一条记录的原因是您有一行

return$表。这意味着，代码执行
foreach
循环中的所有内容，然后当它点击
return
语句时，它从函数返回该值，即停止从函数执行

假设您需要从每个
$vcard
生成的每个
$table
的列表，则需要执行以下操作：

function parse_records($html) {

    // Array to hold all records
    $table = array();  

    foreach($html->find('li.vcard') as $vcard):

        // New array for each record
        $row = array();

        foreach($vcard->find('span.given-name') as $given_name):                    
            $row['given_name'] = (trim(addslashes($given_name->plaintext), " "));
        endforeach; 
        foreach($vcard->find('span.family-name') as $family_name):
            $row['family_name'] = (trim(addslashes($family_name->plaintext)," "));
        endforeach;
        foreach($vcard->find('span.location') as $location):
            $row['location'] = (trim(addslashes($location->plaintext), " "));
        endforeach;
        foreach($vcard->find('span.industry') as $industry):
            $row['industry'] = (trim(addslashes($industry->plaintext), " "));
        endforeach;
        foreach($vcard->find('dd.current-content') as $headline):
            $row['headline'] = (trim(addslashes($headline->plaintext), " "));
        endforeach;
        foreach($vcard->find('a.btn-primary') as $url):
            $row['url'] = addslashes($url->href);
        endforeach;

        // Add row to table
        $table[] = $row;

    endforeach;

    // wait till the end to return the whole thing
    return $table;
}

function parse_records($html)
{
    $tablesList = array();

    foreach($html->find("li.vcard") as $vcard)
    {
        $table = array();

        // Add keys to the table like you are doing.

        $tablesList[] = $table; // Add this table to the tables list.
    }

    // Return the list of all of the tables we produced.

    return $tablesList;
}

在本例中，我将循环生成的每个
$table
数组添加到名为
$tablelist
的数组中，然后返回整个表列表，而不仅仅是生成的第一个
$table
。
我认为您需要另一个
foreach
；）我试过你的代码，先生，但是当我打印r（$records）时，它仍然会给我一条记录。@AjVillalobos那么你的代码还有一个问题，与数组附加无关。也许您的
$html->find（'li.vcard'）
没有返回您期望的结果-这是我开始重构之前的原始代码。它得到了页面的所有li.vcard。先生，它成功了。我拼错了变量名！非常感谢。是的，谢谢先生。现在我的问题是插入它们。我需要一个环吗
While（$i；$iI）也尝试了你的，但像下面的sir一样，结果是一样的。而且你的代码似乎是一样的，我做错了什么？我想问1）你确定你的
return
语句不在
foreach
循环中吗？我推荐
{
和
}
，因为它们比
endforeach更容易阅读（IMO）方法，以及2）什么是
打印（$html->find（“li.vcard”）
打印输出？
