如何捕獲require_once/include_once異常？

Question

我試圖做類似的代碼這一個：

<?php 
$includes = array(
    'non_existing_file.php', //This file doesn't exist. 
); 

foreach ($includes as $include) { 
    try { 
     require_once "$include"; 
    } catch (Exception $e) { 
     $message = $e->getMessage(); 
     echo " 
      <strong> 
       <font color=\"red\"> 
       A error ocurred when trying to include '$include'. 
       Error message: $message 
       </font> 
      </strong> 
     "; 
    } 
} 

我已經試過require_once和include_once，但try catch不逮住例外。 我怎麼能抓住這個致命錯誤/警告異常？

Answer 1

該解決方案（改編自here）工作的罰款對我說：

register_shutdown_function('errorHandler'); 

function errorHandler() { 
    $error = error_get_last(); 
    $type = $error['type']; 
    $message = $error['message']; 
    if ($type == 64 && !empty($message)) { 
     echo " 
      <strong> 
       <font color=\"red\"> 
       Fatal error captured: 
       </font> 
      </strong> 
     "; 
     echo "<pre>"; 
     print_r($error); 
     echo "</pre>"; 
    } 
}

這些函數拋出E_COMPILE_ERROR，並且不能像這樣捕獲。

要處理這些錯誤，請參閱set_error_handler。

由於include/require不會引發異常，請檢查您想包含的文件是否存在並且可讀。例如：

$inc = 'path/to/my/include/file.php' 

if (file_exists($inc) && is_readable($inc)) { 

    include $inc; 

} else { 

    throw new Exception('Include file does not exists or is not readable.'); 
}
