PHP - 在foreach循環中獲取總行

Question

我正在開發一個網站，需要在foreach循環中獲取數組的總行數。

這裏是我的代碼：

$vr = $_GET['vr']; 

$dat = file_get_contents("http://example.com"); //this is a datafeed url. 

$exp = explode("\n", $dat); 

foreach ($exp as $val) { 

if($vr == $val) { 
// here I have the code if string is found in array. They were found, but I want to get how many were found. 
} 

我試過count();功能，但它顯示111111111111111111

我知道這是可能的，但我不知道如何做到這一點。

Answer 1

$num = 0; 
foreach ($exp as $val) { 
    if($vr == $val) { 
     $num++; 
    } 
} 
echo $num;
