PHP數組數沒有工作我

Question

我在txt文件中這一數據爲店鋪的產品：

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 

好了，人們將產品添加到購物卡，而這些產品一般TXT插入

對於恢復我用的是下一個腳本的數據：

<?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); 



?> 

如果我使用的print_r我可以在各種情況下的產品和數量，但我怎麼可以在O得到療法模式，例如用於打印或回聲功能正常使用，我嘗試得到最後的數據顯示，因爲這：

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

Thank's問候

使用下面

<?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/>"; 

} 




?>
