解析错误：数组中出现意外的双引号 [英] Parse Error: Unexpected double quotes in array

问题描述

我有一个类似于下面的数组结构：

I have an array structure similar to below:

$system_data = array(
    87 => array(
        'message' => "{$message_name} logged a new activity.",
        'description' => 'patient logged a new activity',
        'message_type' => 3
    )
)

调用函数时，它会找到引用的消息字符串（来自ID-87），并将相关的 $ message_name 变量值注入字符串。如果我返回一个直接将变量直接插入的静态双引号字符串，则可以使用，但是当我将其转换为数组时（更改字符串的双引号并添加 {$ variable_name} 语法错误，出现以下错误：

When a function is called, it finds the referred message string (from the ID - 87) and injects the related $message_name variable value into the string. It works if I return a static double quoted string that directly injects the variable, but when I transposed this to my array (changing for double quotes on the string and adding the {$variable_name} syntax to it, I get the following error:

解析错误：语法错误，意外的是

Parse error: syntax error, unexpected '"'

从字符串中删除 {$} 即可解决此问题，因此必须意味着引号不会引发数组错误，而是 {$} 会引起双引号错误。有什么想法吗？

Taking the {$} out of my string solves the problem, so that must mean that the double quotes aren't throwing an error with the array, but that it's the {$} throwing an error with the double quotes. Any ideas?

编辑：

根据要求，代码设置如下：

As requested, here's how the code is set:

class Log_model extends CI_Model {
   const SUPERVISOR_PROGRAM_UPDATED = 87;

    private $system_data = array(
        87 => array(
            'message' => "{$message_name} logged a new activity.",
            'description' => 'patient logged a new activity',
            'message_type' => 3
        )
    )

    /*functions here*/
}

推荐答案

有了MikeB和Zgr024的提示，这就是我要解决的问题（不是最好的解决方案，而是可以工作并保持灵活性和动态性的东西）需要我的脚本）：

With MikeB and Zgr024's hints, this is what I've come to (not the best solution, but something that works and keeps the flexibility and dynamicness i need for my script):

class Log_model extends CI_Model {
    const SUPERVISOR_PROGRAM_UPDATED = 87;

    private static $system_data = array(
        87 => array(
            'message' => "{$message_name} logged a new activity.",
            'description' => 'patient logged a new activity',
            'message_type' => 3
        )
    )

    /*data is a set of values (key->value) to be injected into the string (included and retrieved depending on the log_type_id needed when calling this function)*/
    public function generate_message($log_type_id = FALSE, $data = array()){
    $message = self::$system_data [$log_type_id]['message'];
    foreach($data as $key=>$value){
    $message = str_replace("{%".$key."%}", $value, $message, $i);
    }

    return $message;
}

}
