The code is as follows (cannot pass to the view page), but with the preset $file= "/var/www/test11.txt", then you can pass it to what's going on.

function Indexaction () {$file _dir = @$_post["dir"]; File path is current directory$file _name = @$_post["file_name"]; Filename$file = $file _dir. $file _name;$file = "/var/www/test11.txt";$this->view->downfile = $file;echo $this->view->rend

How do you calculate PHP decimals?
if (0.030! = (0.530-0.500+0+0))
{
$s = 0.530-0.500+0+0;
$s = 0.03-$s;
}
This is not equal??
It's not 0 after subtracting.
Is this PHP an alien calculation method?

Portlet application. Based on the principle of separation of content and presentation, it can be understood that the portlet is the content of the portal, while the theme skin is the presentation. As shown in Figure 1.
Figure 1. Portal Page Aggregation
In the version of WebSphere Portal prior to 6.1, there was only one way of page aggregation: server-side aggregation (SSA). The principle of this aggregation is to create a larger JSP file on the s
flow. Goto and CPS can be converted to each other, and all other control flows can be converted to Goto and CPS. They are comparable in this respect. And since a program that is fully processed with the CPS transformation looks like a bunch of instructions, what's the difference? The difference is that CPS can be strongly typed, while Goto is never possible.
As a last piece of nonsense, I give a small example of what is called "a λ-calculus program that has been completely processed with a CPS
