如何在c / c ++ php扩展中包含/要求一个php文件，将变量传递给用户空间范围？

Question

First i need import a file from PHP_FUNCTION(), and passing to imported php file some variables from C function into userspace.

Example:

include_a_file.c

PHP_FUNCTION(include_a_php_file)
{
  zval *var_to_userspace;
  char *str;
  str = "string send to userspace";
  ZVAL_STRING(var_to_userspace, str, 0);

  php_require_once("a_file.php"); // <-- how to?
}

a_file.php

<?php
  print "<pre>";
  vardump($var_to_userspace);
  print "</pre>";
?>

Try to call zend_compile_string():

zval nop;
ZVAL_STRINGL(&nop, "return ;", 8, 0);
zend_compile_string(&nop, "NOP" TSRMLS_CC);

This will return you pointer to zend_op_array struct, which will be holding Zend opcodes for your code. So you can just dump these opcodes once and create zend_op_array struct in your program yourself.
