我在PHP中的每个函数输出都有问题（实际上不知道如何设置代码来做我需要的）。如果foreach中的每个项目都等于某个值，我想输出一些文本。如果我把

I'm having trouble with output in for each function in PHP (actually don't know how to set the code to do what I need). I'd like to output some text if every item in foreach is equal to some value. If I put

foreach($items as $item) {
    if($item == 0){ echo "true"; }
}

我会为每个项目都生效，我只需要输出true所有项目都等于某个值。

I will get true for every item and I need to output true only if all items are equal to some value.

This peice of code work for most type of variables. See how it works in inline comment.

 $count=0; // variable to count the matched words
 foreach ($items as $item)
   {
     if($item == $somevalue)
       {
         $count++; // if any item match, count is plus by 1
       }
   }
 if($count == count($items))
   {
     echo "true"; // if numbers of matched words are equal to the number of items
   }
 else
  {
    echo "false";
  }
