<?php echo "<script>test('$_POST[userid]');</script> "; ?>
在上面的$_POST['']也可适用$_SESSION[' '];
<?php $para = "hello boby!"; echo $para; echo "<script> var para=\"$para\"; alert(para);</script>"; ?>;
<script><br />function show(str){<br /> alert(st);<br />}<br /> <br />show("<?php echo $value; ?>");//将php变量的值输出到JS调用函数的参数里面;<br /></script><br/> <p class="header2"><span class="icon i-relatedanswer"><h3>js函数参数的值传递js与php</script>
按你这样就是在把js的变量拿去php里面使用, 这是不可行的, 无法实现的.
首先你要明白, php脚本是第一时间编译的, 编译完了php才会去执行html,javascript.
我看你的需求可以不需要javascript来做,你的这个sid完全可以用get/post的方式来传值, 如果想无刷新, 则要使用ajax异步来实现.
啰嗦一下:
在js里面可以使用php的变量, 反之不行

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
