我不明白为什么我的代码不起作用。我想将一个字符串与一个已经爆炸的数据数组进行比较，同时它正在被解析。出于某种原因，我在第一个上得到了匹配，但在其余部分上没有。我会很感激这里的任何帮助！我看了又看，但没有找到答案！

通过知道哪个数组元素与哪个字符串匹配，我可以正确存储该数据并对其执行计算。这样做的目的是根据以特定格式输入的原始调查数据创建一系列坐标。

我希望我已经解释得足够好。就像我提到的那样，我一直在寻找答案，但找不到适合我正在做的事情的答案。

感谢我得到的任何帮助，我很感激！

我试过使用 in_array 没有成功， strcmp 没有成功。

这是我的代码： 

   <?php
   $textArea = explode("\r", $_POST['textArea']);
   $i = 0;
   $j = 0;

   foreach ($textArea as $textRows) {
       $j = 0;
       $textRow = explode(",", $textRows);
       foreach ($textRow as $textItem[$i][$j]) {
           if ($j == 0) {
               if (("TR") == ($textItem[$i][$j])) {
                   echo("Traverse <br>");
               }
               if (("CP") == ($textItem[$i][$j])) {
                   echo("Control <br>");
               }
               echo("i = $i, j = $j, textItem = " . $textItem[$i][$j] . "<br>");
           }
           $j++;
        }
       $i++;
   }
   echo($textItem[9][0] . "<br>");
   echo($textItem[0][0] . "<br>");
   echo($textItem[0][3] . "<br>");
   echo($textItem[5][6] . "<br>");
   $_SESSION['textNum'] = $textItem;
   ?>

我当前的输出：

Control

i = 1, j = 0, textItem = CP
i = 2, j = 0, textItem = TR

我想看到的：

Control
i = 1, j = 0, textItem = CP
Traverse
i = 2, j = 0, textItem = TR
Traverse
i = 3, j = 0, textItem = TR
Traverse
i = 4, j = 0, textItem = TR
Traverse
i = 5, j = 0, textItem = TR
Traverse
i = 6, j = 0, textItem = TR
Traverse
i = 7, j = 0, textItem = TR

分解$_POST数组"\n"而不是"\r"，如下所示：

$textArea = explode("\n", $_POST['textArea']);

$i = 0;

foreach ($textArea as $textRows) 
{
    $j = 0;

    $textRow = explode(",", $textRows);

    foreach ($textRow as $textItem[$i][$j]) 
    {
        if ($j == 0) 
        {
            if (("TR") == ($textItem[$i][$j])) 
            {
                echo("Traverse <br>");
            }
            if (("CP") == ($textItem[$i][$j])) 
            {
                echo("Control <br>");
            }
           echo("i = $i, j = $j, textItem = " . $textItem[$i][$j] . "<br>");
       }
       $j++;
    }
   $i++;
}

echo($textItem[9][0] . "<br>");
echo($textItem[0][0] . "<br>");
echo($textItem[0][3] . "<br>");
echo($textItem[5][6] . "<br>");
