Example of script execution time using microsecond in PHP, and microsecond in php
In PHP, most time formats are expressed in UNIX timestamps, while UNIX timestamps are measured in seconds with the smallest unit. This is not accurate enough for some applications, so microtime () can be called to return the current UNIX Timestamp and number of nuances. The function is prototype as follows:Copy codeThe Code is

IronPython is a kind of in. NET and the Python implementation on Mono, launched by Microsoft's Jim Hugunin, is an Open-source project based on Microsoft's DLR engine. IronPython's homepage on CodePlex:http://ironpython.codeplex.com/
Usage scenarios:
If your partner writes Python scripts, and the functionality of most of your projects has been implemented, you don't need to implement them in C #. Now the form is missing, at this point the combination of python+c# can be a perfect ending problem

We sometimes encounter heavy, repetitive work when using lingo, manual operation is obviously time consuming, and the @for function in lingo can only do some simple loops, which requires us to apply the script file to simplify these repetitive work. The English part below is an example from the Official Handbook, which summarizes the 2 points I find useful:1. script

Here The example reads a micaps first class of data (ground full-feature observations), obtains 6-hour accumulated precipitation data (precipitation6h), and then uses the Griddata function of the site data to interpolate the

services, greatly increased maintainability, This is one of the reasons why fcgi and other similar patterns are so popular.
However, it is because of this model, but also brings a number of problems. For example, the "Nginx File Parsing Vulnerability" released by 80sec last year is actually a problem because of fcgi and Webserver's understanding of the script path-level parameters. In addition, since fcgi
In 4.0, the most important major changes are as follows:
-Allow arrays to be directly assigned to each other and allow arrays to be parameters of a function.
-Lets you call a function declared later in a function, that is, the function declaration has nothing to do with the calling relationship. Make indirect recursion possible.
-Allows global variables to be defined at the script location after the function is defined. You can also declare a global v
