這基本上是一個 csv 具有以下列，

id  title   link    description condition   price   availability    image_link  gtin    brand   mpn google_product_category product_type    item_group_id

我正在嘗試閱讀專欄

<?php
$row = 1;
if (($handle = fopen("google_base.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo '<pre>';
            print_r($data);
            echo '</pre>';
        }
    }
    fclose($handle);
}

或者

<?php
$row = 1;
if (($handle = fopen("google_base.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { 
    echo '<pre>';
       print_r($data);
       echo '</pre>';
    }
    fclose($handle);
}

但是生成的 arrays 並沒有生成組織良好的行數據及其各自的列。

我可以查看此工具上的列https://www.convertcsv.com/csv-viewer-editor.htm

我怎樣才能按列名讀取一行？

Answer 1

使用制表符分隔符來讀取這樣的各個行

<?php
$row = 1;
if (($handle = fopen("google_base.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, "\t")) !== FALSE) { 
    echo '<pre>';
       echo $data[0].'</br>';
       echo '</pre>';
    }
    fclose($handle);
}
