php脚本中的双引号echo

Double quotes within php script echo(php脚本中的双引号echo)

问题描述

我有一行 php 代码，如下所示:

I have a line of php code that looks like this:

echo "<script>$('#edit_errors').html('<h3><em>Please Correct Errors Before Proceeding</em></h3>')</script>";

我想知道如何正确地为文本添加字体颜色.如果我这样做:

I would like to know how to add a font color to the text correctly. If I do this:

echo "<script>$('#edit_errors').html('<h3><em><font color="red">Please Correct Errors Before Proceeding</font></em></h3>')</script>";

red"这个词是黑色的，编译器会报错.

The word "red" is in black text and the compiler throws an error.

如果我在红色周围使用单引号，则文本根本不会显示.

If I use single quotes around red, then the text does not show up at all.

任何帮助都会很棒.谢谢

Any help would be great. Thanks

推荐答案

你需要转义 "，所以它不会被解释为字符串的结尾.使用 逃避它:

You need to escape ", so it won't be interpreted as end of string. Use to escape it:

echo "<script>$('#edit_errors').html('<h3><em><font color="red">Please Correct Errors Before Proceeding</font></em></h3>')</script>";
