Question

我试图使用PHP将字符串输出到JS文件中。这是PHP代码

$embedded_form_js = "document.addEventListener('DOMContentLoaded', function(){
        var parts = window.location.search.substr(1).split('&');
        var $_GET = {};
        for (var i = 0; i < parts.length; i++) {
            var temp = parts[i].split('=');
            $_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);
        }


        var ref = $_GET['ref'];

        if (ref === 'undefined')
        {
            ref = 0;
        }

}, false);";

我试图写一个像这样的JS文件

$fp = fopen("FOLDER/FILE.js", 'w');
fwrite($fp, $embedded_form_js);
fclose($fp);

问题在于，当我尝试编写JS文件时，会发生此错误。

syntax error, unexpected '(', expecting ']'

这是参考这一行：

$_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);

我该如何解决这个问题？

使用Nowdocs，因为它是单引号，不会尝试解释$ _GET

$embedded_form_js = <<<'EOS'
        document.addEventListener('DOMContentLoaded', function(){
        var parts = window.location.search.substr(1).split('&');
        var $_GET = {};
        for (var i = 0; i < parts.length; i++) {
            var temp = parts[i].split('=');
            $_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);
        }


        var ref = $_GET['ref'];

        if (ref === 'undefined')
        {
            ref = 0;
        }

}, false);
EOS;

将PHP字符串输出到JS文件会导致语法错误
