You can echo the PHP variable into your javascript while your page is created. 您可以在创建页面时将PHP变量回显到javascript中。
<script type="text/javascript">
var name = "<?php echo $name; ?>";
</script>
OR 要么
<script type="text/javascript">
var name = "<?=$name;?>";
</script>
Of course this is for simple variables and not objects. 当然，这是针对简单变量而不是对象。

Generate part of your JavaScript by PHP: 通过PHP生成部分JavaScript：
<?php
$name = "john";
echo "<javascript>var name = \"" . $name . "\";</javascript>";
?>

Eg. 例如。
<?php
$name = "john"
?>
<script>
var myJSVar = <?php echo $name; ?>
alert(myJSVar);
</script>
In the above case, Your PHP variable must have defined before being accessed by JavaScript. 在上述情况下，必须先定义您的PHP变量，然后才能被JavaScript访问。

Why don't you set the PHP variable inside a hidden <div> like this: 为什么不这样在隐藏的<div>设置PHP变量：
<div id="myvar" class="hidden"><?php echo $myphpvar; ?></div>
CSS: CSS：
.hidden {display: none; visibility: hidden;}
JavaScript: JavaScript：
var phpvar = document.getElementById('myvar').innerHTML;
