从PHP回显JavaScript [英] Echoing javascript from PHP

问题描述

我正在尝试从PHP中回显一些Google Analytics（分析）JavaScript代码，以便可以根据特定情况有条件地对其进行读取。因为代码中包含/ * * /字符，所以我难以理解引号。我正在寻找将这种类型的文本分配给php变量的方向。

I am trying to echo some google analytics javascript code from PHP so it can be conditionally read based on specific scenarios. I'm having difficulty wrapping my head around the quoting since the code contains /* */ characters. I'm looking for some direction in assigning this type of text to a php variable.

谢谢

$sJS .='<script type="text/javascript">';
$sJS .='/* <![CDATA[ */"';
$sJS .='var google_conversion_language = "en";';
$sJS .='var google_conversion_format = "2";';
$sJS .='var google_conversion_color = "ffffff";';
$sJS .='var google_conversion_value = 0;';
$sJS .='/* ]]> */';
$sJS .='</script>';
$sJS .='<script type="text/javascript" src="http://www.googleadservices.com/page.js">';
$sJS .='</script>';
$sJS .='<noscript>';
$sJS .='<div style="display:inline;">';
$sJS .='<img height="1" width="1" style="border-style:none;" alt="" src="http://www.googleadservices.com/pagead/conversion/997410413/?value=1.00&amp;label=ffr456dj5QIQ7YzN2wM&amp;guid=ON&amp;script=0"/>';
$sJS .='</div>';
$sJS .='</noscript>';

推荐答案

您不需要像这样逐行执行... PHP支持继续到下一行。效果很好：

You don't need to do it line by line like that... PHP supports continuation to the next line. This works just fine:

$sJS = '<script type="text/javascript">
    /* <![CDATA[ */
    var google_conversion_language = "en";
    var google_conversion_format = "2";
    var google_conversion_color = "ffffff";
    var google_conversion_value = 0;
    /* ]]> */
    </script>
    <script type="text/javascript" src="http://www.googleadservices.com/page.js">
    </script>
    <noscript>
    <div style="display:inline;">
    <img height="1" width="1" style="border-style:none;" alt="" src="http://www.googleadservices.com/pagead/conversion/997410413/?value=1.00&amp;label=ffr456dj5QIQ7YzN2wM&amp;guid=ON&amp;script=0"/>
    </div>
    </noscript>';

您的字符串用单引号引起来，其中没有单引号，也没有反斜杠或转义序列。

Your string is quoted with single quotes, there are no single quotes inside of it, and there are no backslashes or escape sequences.
