Question

我在PHP新手...有4個數組，我想顯示，但它不顯示任何內容....

請與代碼

$new_strip_from_name[] = $strip_from_name; 
$new_from_name[] = $from_name; 
$new_to_name[] = $to_name; 
$new_lastdata[] = $lastdata; 

echo "<table style='border: 2px solid black; text-align:left'>";  
    foreach($new_from_name as $from_name2){ 
     foreach($new_lastdata as $lastdata2){ 
      foreach($new_to_name as $to_name2){ 
       foreach($new_strip_from_name as $key => $value){     
        if((strpos($lastdata2, $value) !==FALSE)){     
        echo "<tr>"; 
        echo "<td>$from_name2</td>"; 
        echo "<td>$to_name2</td>"; 
        echo "<td>$lastdata2</td>"; 
        echo "</tr>"; 
        } 

       } 
      } 
     } 
    } 
echo "</table>"; 

樣品陣列指

$new_strip_from_name = array("okay"); 
$from_name; = array("john", "mar", "jeff"); 
$to_name; = array("phil", "india", "japan"); 
$lastdata; = array("john@okay", "mar@okay", "jeff@not"); 

期望的輸出

好吧，現在我們看到你想要的東西！但它不會像這樣工作。最好的辦法是創建一個類 - >http://php.net/manual/en/language.oop5.basic.php。但這裏一個基本的解決方案，它可以工作：

$messages = array(); 
$message = array(); 
$message['from'] = "john"; 
$message['to'] = "phil"; 
$message['lastdata'] = "john@okay"; 

array_push($messages, $message); 

這樣做對每封郵件或不管它是什麼，然後這樣的：

foreach ($messages as $message){ 
    if (strpos($message,"okay") !== false){ 
     echo "<tr>"; 
     echo "<td>".$message['from']."</td>"; 
     echo "<td>".$message['to']."</td>"; 
     echo "<td>".$message['lastdata']."</td>"; 
     echo "</tr>"; 
    } 
}

這anwser應該與當前數據結構的工作，但這不是清潔。這不是應該的方式，每個消息應該有1個元素，而不是4個消息的4個數組，這可能會導致一些嚴重的混淆問題。如果可能，您應該更改數據的收集或​​創建。但無論如何嘗試這個：

$new_strip_from_name[] = $strip_from_name; 
$new_from_name[] = $from_name; 
$new_to_name[] = $to_name; 
$new_lastdata[] = $lastdata; 

echo "<table style='border: 2px solid black; text-align:left'>"; 
for ($i = 0; $i < sizeof($new_from_name); $i++){ 
    if (strpos($new_lastdata[$i],"okay") !== false){ 
    echo "<tr>"; 
    echo "<td>".$new_from_name[$i]."</td>"; 
    echo "<td>".$new_to_name[$i]."</td>"; 
    echo "<td>".$new_lastdata[$i]."</td>"; 
    echo "</tr>"; 
    } 
} 
echo "</table>";
