Question

我在txt文件中有这个商店产品的数据：

product 1
product 1
product 2
product 2
product 2
product 1
product 1
product 3
product 3
product 3
product 1
product 1
product 3
product 1

好的，人们将产品添加到购物卡中，这些产品一般都插入txt

要恢复数据，请使用下一个脚本：

<?php

$file_data=file("products.txt");


for ($i=0;$i<sizeof($file_data);$i++)
{


/// Create array of groups


$global_products[]=$file_data[$i];

}


/// Now i want get the products and the number in each case for example of the product 1 i have 6 for the product 2 i have 3 and for the product 3 i have 4 , ok for get this i can use thi function 




$prr=array_count_values($global_productos);

print_r (object2array($prr),true);



?>

如果我使用print_r，我可以获得每种情况下的产品和编号，但我可以如何进入其他模式，例如用于打印或回波的正常功能，我尝试最后得到数据显示为：

Product 1 (6)
Product 2 (3)
Product 3 (4)

感谢问候

使用以下代码

<?php

$file_data=file("output_rrr.txt");


for ($i=0;$i<sizeof($file_data);$i++)
{


/// Create array of groups


$global_products[]=$file_data[$i];

}

/// Now i want get the products and the number in each case for example of the product 1 i have 6 for the product 2 i have 3 and for the product 3 i have 4 , ok for get this i can use thi function 




$prr=array_count_values($global_products);
foreach($prr as $key=>$value)
{
    echo trim($key).": ".$value."<br/>";

}




?>
