PHP数组声明

Question

for ($k = 0; $k < $count; $k++) {
    $master[$k] = $namearray[$k], $streetarray[$k], $localityarray[$k], $regionarray[$k], $postalcodearray[$k], $phonearray[$k];
}

我想声明一个新数组并从已声明的其他数组中设置值.我以为我可以循环键并设置值,但这对我不起作用.

完整代码如下.我正在解析黄页搜索结果并尝试将搜索结果输出到csv文件中.在下面的代码中,我删除了循环,只向数组添加了一些值,以确保我的错误不是别的.

<?php

            // include required functions
            include('simple_html_dom.php');

            $url = "http://www.yellowpages.com/" . $_POST['city'] . '-' . $_POST['state'] . '-' . $_POST['postalcode'] . '/' . $_POST['category'] . '?g=' . $_POST['city'] . '%2C+' . $_POST['state'] . '+' . $_POST['postalcode'] . '&q=' . $_POST['category'];

            // get DOM from URL
            $html = file_get_html($url);


            // find all business name
            foreach($html->find('h3.business-name') as $name)
                //echo $name->innertext . '<br />';
                $namearray[] = $name->innertext;

            foreach($html->find('span.postal-code') as $postalcode)
                //echo $postalcode->innertext . '<br />';
                $postalcodearray[] = $postalcode->innertext;                

            // find all business phone
            foreach($html->find('span.business-phone') as $phone)
                //echo $phone->innertext . '<br />';

        $list = array (
            array($namearray[0], $streetarray[0], $localityarray[0], $regionarray[0], $postalcodearray[0], $phonearray[0]),
            array($namearray[1], $streetarray[1], $localityarray[1], $regionarray[1], $postalcodearray[1], $phonearray[1]),

            array($namearray[3], $streetarray[3], $localityarray[3], $regionarray[3], $postalcodearray[3], $phonearray[3])

        $fp = fopen('hrpsearch.csv', 'w');

        foreach ($list as $fields) {
            fputcsv($fp, $fields);
        }

        fclose($fp);

        ?>

尝试:

$master = array();
for ($k = 0; $k < $count; $k++) {
    $master[$k] = array
        ( $namearray[$k]
        , $streetarray[$k]
        , $localityarray[$k]
        , $regionarray[$k]
        , $postalcodearray[$k]
        , $phonearray[$k]
        );
}

这将为您创建一个新的二维数组,并为每个子数组创建关联键.
