breakpoint current

基本解释

The debugger will encounter that breakpoint and break execution on the way out of the current calls.
调试器会在退出当前的调用过程中遇到该断点并中断执行。
Turns the breakpoint either on or off, depending on its current state, at the current location in the file.
在文件的当前位置，根据其当前状态打开或关闭断点。
Besides that, you need to do more than set a breakpoint to flush the current display data to your Web browser, so define your test4.php file, as shown below and in Figure 8 above.
除此之外，需要做的不仅仅是设置一个断点把当前显示数据刷新到 Web 浏览器，所以要像下面和图 8 所示那样定义 test4.php。
