Remove HTML tags when exporting from MYSQL to Excel PHP

本文关键字：Excel PHP MYSQL HTML 标签删除 | 更新日期: 2023-09-27

我正在寻找有关从MYSQL数据库字段中删除HTML标签导出到excel时的帮助。

例如，当我导出时，我看到

<BR>Testing actions and comments box

我的代码

$file_ending = "xls";
//header info for browser
header("Content-Type: application/xls");    
header("Content-Disposition: attachment; filename=excel.xls");  
header("Pragma: no-cache"); 
header("Expires: 0");
/*******Start of Formatting for Excel*******/   
//define separator (defines columns in excel & tabs in word)
$sep = "'t"; //tabbed character
//start of printing column names as names of MySQL fields
for ($i = 0; $i < mysql_num_fields($result); $i++) {
echo mysql_field_name($result,$i) . "'t";
}
print("'n");    
//end of printing column names  
//start while loop to get data
    while($row = mysql_fetch_row($result))
    {
        $schema_insert = "";
        for($j=0; $j<mysql_num_fields($result);$j++)
        {
            if(!isset($row[$j]))
                $schema_insert .= "NULL".$sep;
            elseif ($row[$j] != "")
                $schema_insert .= "$row[$j]".$sep;
            else
                $schema_insert .= "".$sep;
        }
        $schema_insert = str_replace($sep."$", "", $schema_insert);
        $schema_insert = preg_replace("/'r'n|'n'r|'n|'r/", " ", $schema_insert);
        $schema_insert .= "'t";
        print(trim($schema_insert));
        print "'n";
    }

这个问题已经回答过好几次了:删除html标签

你可以在下面看到一些细节

基于PHP官方文档:http://www.php.net//manual/en/function.strip-tags.php

你应该使用条带标签:

<?php
$text = '<p>Test paragraph.</p><!-- Comment --> <a href="#fragment">Other text</a>';
echo strip_tags($text);
echo "'n";
// Allow <p> and <a>
echo strip_tags($text, '<p><a>');
?>

输出:

Test paragraph. Other text
<p>Test paragraph.</p> <a href="#fragment">Other text</a>

HTML不能使用正则表达式解析:使用正则表达式解析HTML:为什么不呢?

我建议考虑使用库进行HTML解析。也有免费的，比如http://htmlpurifier.org/。
