我想知道是否有可能将PHP代码写入文件.例如:
fwrite($handle, "<?php $var = $var2 ?>");
Run Code Online (Sandbox Code Playgroud)
我希望它在文件中产生确切的字符串,而不是eval的代码.这可能吗?
我目前得到以下输出(其中$ var = 1和$ var2 = 2):
<?php 1 = 2 ?>

虽然我想要实际的字符串:
<?php $var = $var2 ?>

我似乎在PHP/JS之间向后和向前转换数组时遇到问题.我正在使用JavaScript中的XmlHttpRequest到PHP页面,该页面使用json_encode编码多维(2D)数组.
当接收字符串时,我使用JSON.parse()来解码字符串,但它作为一维数组返回.有没有办法将JSON字符串解析为多维数组而不是单维?
收到的JSON示例(来自CSV文件):

我并不认为这是一个错误,我只是想知道机器内部究竟发生了什么.
