PHP：合并所有 CSV 文件行中的 2 列

Question

成功的代码将

• 打开 csv 文件
• 合并2个字段的内容
• 将这些合并值放入另一个现有字段中
• 创建包含合并字段的新 csv 文件

开始 CSV 文件示例：

产品名称、产品类型、尺寸、类别、子类别

Lite 1/2 桶，啤酒，1/2 桶，比尔森啤酒

Bud Light 1/2 桶，啤酒，1/2 桶，比尔森啤酒

预期结束的 CSV 文件：

产品名称、产品类型、尺寸、类别、子类别

Lite 1/2 桶,啤酒,1/2 桶,啤酒;1/2 桶;pilser,pilsner

Bud Light 1/2 桶,啤酒,1/2 桶,啤酒;1/2 桶;pilser,pilsner

Answer 1

这是我找到的解决方案。可能不是最优雅的。

<?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>";
?>
