        $pattern = preg_quote($searchfor, '/');
        $pattern = "/^.*$pattern.*\$/m";


        if (preg_match($pattern . "i", $content, $matches)) {

            echo '<br>';
            echo "Found matches:\n";
            echo implode("\n", $matches);
        } else {
            echo "No matches found";
        }
    } else {
        echo 'Couldn\'t the file. Please check that file.';
    }}

这是要从文档文件中搜索关键字。但是当我运行它时，第一次循环工作然后下次显示重新声明函数的致命错误。我无法理解这一点。所以请帮助我。

<?php
    $searchfor = $_REQUEST["search"];

    /* Declare the function outside the loop */

    function read_file_docx($filename) {
        $stripped_content = '';
        $content = '';

        if (!$filename || !file_exists($filename)) return false;
        $zip = zip_open($filename);
        if (!$zip || is_numeric($zip)) return false;

        while ($zip_entry = zip_read($zip)) {
            if (zip_entry_open($zip, $zip_entry) == FALSE)  continue;
            if (zip_entry_name($zip_entry) != "word/document.xml") continue;
            $content .= zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
            zip_entry_close($zip_entry);
        }

        } else {
            echo 'Couldn\'t the file. Please check that file.';
        }
    }
?>

无法重新声明read_file_docx（）
