### Description

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

This function is EXPERIMENTAL. The behaviour of this function, the its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.

### Parameters

`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.

### Return Values

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

### Examples

', $errors, PARSEKIT_QUIET);
var_dump($ops);
?>`
