xhprof 在5.6+版本的php中报错

xhprof 在5.6+版本的php中使用会报错，原因是因为array_pop函数处理没有兼容新版本，只需要修改xhprof.c源码中的

#if ZEND_EXTENSION_API_NO >= 220121212
    /* PHP 5.5. This is just inlining a copy of execute_internal(). */

    if (fci != NULL) {
      ((zend_internal_function *) execute_data->function_state.function)->handler(
        fci->param_count,
        *fci->retval_ptr_ptr,
        fci->retval_ptr_ptr,
        fci->object_ptr,
        1 TSRMLS_CC);
    } else {
      zval **return_value_ptr = &EX_TMP_VAR(execute_data, execute_data->opline->result.var)->var.ptr;
      ((zend_internal_function *) execute_data->function_state.function)->handler(
        execute_data->opline->extended_value,
        *return_value_ptr,
        (execute_data->function_state.function->common.fn_flags & ZEND_ACC_RETURN_REFERENCE)
          ? return_value_ptr
          : NULL,
        execute_data->object,
        ret TSRMLS_CC);
    }
#elif ZEND_EXTENSION_API_NO >= 220100525

改成下面这样

#if ZEND_EXTENSION_API_NO >= 220121212
    /* PHP 5.5. This is just inlining a copy of execute_internal(). */

    if (fci != NULL) {
      ((zend_internal_function *) execute_data->function_state.function)->handler(
        fci->param_count,
        *fci->retval_ptr_ptr,
        fci->retval_ptr_ptr,
        fci->object_ptr,
        1 TSRMLS_CC);
    } else {
      zval **return_value_ptr = &EX_TMP_VAR(current_data, current_data->opline->result.var)->var.ptr;
      current_data->function_state.function->internal_function.handler(
              current_data->opline->extended_value + current_data->call->num_additional_args,
            *return_value_ptr, return_value_ptr,
            current_data->object, ret TSRMLS_CC
        );
    }

就可以了
