PHP。合并CSV文件中的2列行

Question

成功的代码将

• 打开csv文件
• 合并2个字段的内容
• 将这些合并的值放到另一个现有的字段中
• 创建新的合并字段的csv文件。

启动CSV文件的例子。

产品名称，产品类型，尺寸，类别，子类别。

12桶啤酒,12桶啤酒,比尔森啤酒

百威啤酒12桶,啤酒,12桶,,比尔森啤酒

预计CSV文件结束。

product_name,producttype,size,category,sub_category。

12桶啤酒,12桶啤酒,12桶啤酒;12桶啤酒;比尔森啤酒,比尔森啤酒

百威啤酒12桶,啤酒,12桶,啤酒;12桶;比尔森,比尔森啤酒。

Answer 1

这是我找到的解决方案。可能不是最优雅的一个。

<?php
//Brand_Name	Brand_Description	SKUNumber	UPC	product_type	CATEGORY	SUB-CATEGORY	BEER TYPE	BEER STYLE	PRODUCER	price_regular	Size	Web Active	Quantity_Available
$columns = ["Brand_Name","Brand_Description","SKUNumber","UPC","product_type","CATEGORY","SUB-CATEGORY","BEER TYPE","BEER STYLE","PRODUCER","price_regular","Size","Web Active","Quantity_Available"];
//$columns = ["sku","category","description","image","small_image","thumbnail", "price","color"];

$file = fopen("Products_In.csv", "r"); //Open the old file for reading
$newFile = fopen("Products_Out.csv", "w"); //Create a new file for writing

while (($data = fgetcsv($file)) !== FALSE) {
    $row = array_combine($columns, $data);
    if(!empty($row['BEER TYPE'])){
	    $category = "{$row['product_type']};{$row['Size']};{$row['BEER TYPE']}";
    } else {  
	    $category = "{$row['product_type']};{$row['Size']}";
    }
	$row['SUB-CATEGORY'] = $category;
    fputcsv($newFile, array_values($row)); //write data into new file
}

fclose($file);
fclose($newFile);
echo "<h1>Categories updated</h1>";
?>
