Php数组对我来说没用

我在txt文件中有以下商店产品的数据：

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，然后将这些产品插入到一般文本中

要恢复数据，我使用下一个脚本：

感谢您的问候使用下面的代码

<?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/>";

}




?>

---

循环遍历数组$prr并以您喜欢的方式打印每个条目。我猜op想要计算文件中每个产品的眼病数。您能告诉我如何做到这一点吗，您能举个例子吗，谢谢！！！

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

<?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/>";

}




?>
