Question

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

I’d like to declare a new array and set values from other arrays already declared. I thought I could just loop through the keys and set the values but this doesn’t work for me.

Full code below. I’m parsing yellow pages search results and trying to output search results into a csv file. In the code below I removed the loop and only added a few values to the array to make sure my bug wasn’t something else.

<?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;

            // find all business street address
            foreach($html->find('span.street-address') as $street) 
                //echo $street->innertext . '<br />';
                $streetarray[] = $street->innertext;

            // find all business city
            foreach($html->find('span.locality') as $locality)
                //echo $locality->innertext . '<br />';
                $localityarray[] = $locality->innertext;            

            // find all business state
            foreach($html->find('span.region') as $region)
                //echo $region->innertext . '<br />';
                $regionarray[] = $region->innertext;            

            // find all business postal code
            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 />';
                $phonearray[] = $phone->innertext;

        ?>
        <p>Search results for: <?php echo $_POST['category'] . ' ' . $_POST['city'] . ' ' . $_POST['state'] . ' ' . $_POST['postalcode'];  ?></p>
        <?php
            // Output results
            $count = count($namearray);
            for ($i = 0; $i < $count; $i++) {
                echo $namearray[$i] . '<br />';
                echo $streetarray[$i] . '<br />';
                echo $localityarray[$i] . ',' . $regionarray[$i] . ' ' . $postalcodearray[$i] . '<br />';
                echo $phonearray[$i] . '<br />' . '<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[2], $streetarray[2], $localityarray[2], $regionarray[2], $postalcodearray[2], $phonearray[2]),
            array($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);

        ?>

Try:

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

This will create a new two-dimensional array for you with associated keys for every child array.
