How to use php variables in js code
The easiest way to introduce PHP variables into JavaScript is to mix them. Another way is to introduce them through shtml. However, shtml introduction requires server permission and the output file needs to be set independently. , which is relatively complex and does not conform to the trend of dynamic scripts. Here is a brief introduction to the implementation method of the hybrid method.
Hybrid coding method:
Hybrid coding is to use the mixed coding method of HTML and PHP code to realize the way of running PHP in HTML.
Notes:
1. The file must be a php file. Otherwise, php cannot be run directly.
2. Where you need to run and output php, you must write a complete php reference tag, that is, format.
3. The php tags in the mix must have an end, otherwise it will easily lead to exceptions in the html part.
Case:
File name: text.php
<!DOCTYPE html>
<html>
<head>
<title>php与html混编</title>
</head>
<body>
<!--html注释:这里我们直接使用php来模拟一下欢迎提示语-->
尊敬的<?php echo '熊大';?>(先生/女士),您好,欢迎您来到我的小站.<br>
<?php $name = '熊二';?>
<script>
alert("哎呀,<?php echo '熊大';?>你来了啊!");
var name = "<?php echo $name;?>";
// 引用php的变量
alert(name);
</script>
</body>
</html>The above code must be placed in the php file, and then visit the page to see the effect .
This achieves the purpose of outputting php variables in html.
