"1"代表什么?意味着在php print_r语句的末尾? [英] What does "1" mean at the end of a php print_r statement?

问题描述

我的print_r($view)函数产生:

View Object
(
    [viewArray:View:private] => Array
        (
            [title] => Projet JDelage
        )
)
1 <--------------

最后的"1"是什么意思? PHP手册对如何解析print_r的输出不是很清楚.

What does the "1" at the end mean? The PHP manual isn't very clear on how to parse the output of print_r.

推荐答案

您可能拥有echo print_r($view).删除echo构造.而且...您需要解析其输出什么?当然，有更好的方法可以解决您的问题.

You probably have echo print_r($view). Remove the echo construct. And... what need do you have to parse its output? There are certainly much better ways to solve your problem.
