转义PHP输出的HTML属性的双引号

Often when writing PHP I'll have it output some HTML like this -

通常在编写PHP时我会输出一些像这样的HTML -

echo "<a href="../" title="link title">".$link_text."</a>";

Obviously this won't parse as I need to escape the double quotes in the attributes of the <a> element. Is there a regex that would quickly do this rather than me manually adding the backslashes?

显然这不会解析,因为我需要在元素的属性中转义双引号。是否有正则表达式会快速执行此操作而不是手动添加反斜杠?

One other thing - the regex shouldn't escape double quotes outside of the tag (e.g. where I've appended the $link_text variable.

另一件事 - 正则表达式不应该在标记之外转义双引号(例如我附加了$ link_text变量的地方)。

Any ideas?

6 个解决方案

#1

You should just use single-quotes instead:

你应该只使用单引号:

echo '<a href="../" title="link title">' . $link_text . '</a>';

#2

Solutions I can come up with (not without escaping):

我能提出的解决方案(并非没有逃脱):

Single quotes

echo '<a href="../">' . $link_text. '</a>';

单引号echo' '。 $ LINK_TEXT。 '的';

Use double quotes

使用双引号
```
echo "<a href='../'>$link_text</a>";
```

Sprintf

echo sprintf('<a href="../">%s</a>', $link_text);

Sprintf echo sprintf('%s ',$ link_text);

Use HEREDOC

echo <<<EOF
<a href="../">$link_text</a>
EOF;

使用HEREDOC echo <<< EOF $ link_text EOF;

Use template engine like smarty

像smarty一样使用模板引擎

Exit PHP-mode:

?><a href="../"><?php echo $link_text ?></a><?php // other code...

退出PHP模式:?>

BTW, be sure to use htmlspecialchars() on $link_text variable, or you’ll have a XSS security hole.

顺便说一句,一定要在$ link_text变量上使用htmlspecialchars(),否则你将有一个XSS安全漏洞。

#3

Use (This syntax dont worry about quotes etc)

使用(这种语法不用担心引号等)

echo <<<EOT
<a href="../" title="link title">$link_text</a>
EOT;

#4

I'd strongly suggest using templating instead of trying to build strings.

我强烈建议使用模板而不是尝试构建字符串。

In raw PHP:

在原始PHP中:

<a href="../" title="link title"><?php echo $link_text; ?></a>

#5

use single quotes or use heredoc. I'd prefer the last.

使用单引号或使用heredoc。我更喜欢最后一个。

#6

I think you can use

我想你可以用

http://www.example.com/.../Learning-Tutorials/ACTIVE-USER-ACCOUNT/verify.php?email='.$email.'&hash='.$hash.'

"<a href="//www.example.com/.../Learning-Tutorials/ACTIVE-USER-ACCOUNT/verify.php?email="$email&hash=$hash>Click Here to Active</a>"

try it.
