parsekit_compile_string — Compile a string of PHP code and return the resulting op array

### 说明

parsekit_compile_string ( string `$phpcode` [, array `&$errors` [, int `$options` = PARSEKIT_QUIET ]] ) : array
Warning

此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。

### 参数

`phpcode`

  A string containing phpcode. Similar to the argument to eval().

`errors`

  A 2D hash of errors (including fatal errors) encountered during compilation. Returned by reference.

`options`

  One of either `PARSEKIT_QUIET` or `PARSEKIT_SIMPLE`. To produce varying degrees of verbosity in the returned output.

### 返回值

Returns a complex multi-layer array structure as detailed below.

### 范例

Example #1 parsekit_compile_string() example

    <?php
      $ops = parsekit_compile_string('
    echo "Foo\n";
    ', $errors, PARSEKIT_QUIET);

      var_dump($ops);
    ?>

以上例程会输出：
