Question

我完成了代码，就像这样：

<?php
 ini_set('memory_limit', '128M');

    function validate_xml(&$filename)
    {
    libxml_use_internal_errors(true);
    $doc = new DOMDocument('1.0', 'utf-8');
    $xml = file_get_contents($filename); 
    $doc->loadXML($xml); 

    $errors = libxml_get_errors();


    $lines = file($filename);
    $output = fopen('errors.txt', 'a');

    $distinctErrors = array();
    foreach ($errors as $error)
    {
        if (!array_key_exists($error->line, $distinctErrors))
        {
            $distinctErrors[$error->line] = $error->message;
            fwrite($output, "Filename: {$filename}.  Error on line: {$error->line}. {$lines[$error->line-1]}\n");

        }
    }

    fclose($output);

}


if(isset($_POST['SubmitCheck'])) {


        $directory = $_POST['Path'];

        if ( ! is_dir($directory)) {
              exit('Invalid diretory path');
                }
                else
                {
                  echo "The dir is: $directory". '<br />';
                        chdir($directory);

                        foreach (glob("*.xml") as $filename) {  
                        validate_xml($filename);                        
                        }  
              }
        }

        else {

        ?>
        <form id="Form1" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
            Path: <input type="text" name="Path"><br>
            <input type="hidden" name="SubmitCheck" value="sent">
            <input type="Submit" name="Form1_Submit" value="Path">
        </form>
        <?php
        }
?>

它给了我

事情是我有3个大xmls（每个11MB）。当我尝试3个小xmls上的脚本时，它工作。还为每个大xml单独工作。我不知道该做什么，我试着增加php_ini的内存限制......仍然不知道发生了什么。

第23行中的代码具有无效的偏移引用（`{$ lines [$ error-＆gt; line-1}）。你写道：

fwrite($output, "Filename: {$filename}.  Error on line: {$error->line}. {$lines[$error->line-1]}\n");

我想你想做：

$line_text = $lines[ $error->line - 1 ];
fwrite($output, "Filename: {$filename}.  Error on line: {$error->line}. $line_text \n");

你正在做的事情，PHP引擎正在解释$error->line-1，好像$line-1是$error的属性而不是算术运算“$ line减1”。

注意：未定义的偏移量：
