Array and string offset access syntax with curly braces is deprecated

这个警告信息意味着使用花括号 `{}` 访问数组或字符串的偏移量已经过时了。从 PHP 7.4 开始,PHP 引擎将会抛出一个 E_DEPRECATED 级别的警告信息。
如果你使用了这种语法,可以将它改成使用方括号 `[]` 来访问数组或字符串的偏移量。例如,将 `$array{0}` 改为 `$array[0]`。
如果你不想看到这个警告信息,可以在 php.ini 文件中将 `error_reporting` 设置为除 E_DEPRECATED 以外的所有错误级别,或者在代码中使用 `error_reporting()` 函数来设置错误级别。

array and string offset access ayntax with curly braces is deprecated
Array and string offset access using curly braces syntax in PHP is considered deprecated. This means that the way you used to access elements in arrays or strings, like `array` or `$string{"key"}`, is no longer recommended for new code according to the latest PHP language standards. Instead, developers are encouraged to use square bracket notation `array[0]` or `[$string, "key"]`.
The reason behind this deprecation is that curly braces were originally meant for accessing object properties, not array elements. Square brackets have become the standard and more consistent way to access array items in modern PHP, promoting better readability and maintainability.
Here's what you should do to update your code:
- **To access an array element**: Replace `array{index}` with `array[index]`.
- **To access a string value by key**: Replace `$string{"key"}` with `$string["key"]`.
If you're working on an existing project, consider updating these occurrences for better coding practices and compatibility with future versions of PHP.
phpstudyArray and string offset access syntax with curly braces is no longer supported
在PHP7.4及之后的版本中,不再支持使用花括号来访问数组或字符串的偏移,因此会出现“Array and string offset access syntax with curly braces is no longer supported”的错误提示。解决方法是将代码中的花括号{}替换为方括号[]。如果你使用的是PHP8.0版本,直接运行程序会报错,需要将代码中的花括号{}替换为方括号[]后再运行程序。下面是一个修改后的例子:
```php
// 修改前
$str = "hello";
echo $str{0}; // 报错:Array and string offset access syntax with curly braces is no longer supported
// 修改后
$str = "hello";
echo $str[0]; // 输出:h
```
