PHP is one of the lesser known languages ‚Äã‚Äãthat is sometimes mentioned to budding web developers who are looking for tools they should learn from. Although HTML, CSS, and Javascript are absolute essentials, the state and usefulness of PHP is somewhat obscure. we are ready to present what we have learned to help you decide if PHP is something you should invest some time in exploring.

What is PHP?

PHP is a server side script. server side ’ activity occurs when a browser requests information from the website of the server where it is stored. the server then returns the HTML code where the website is written. This is different from the client "side" activity that takes place in a user’s browser and typically includes CSS styling that allows you to view a website.

Scripting basically means code written to automate some process that would otherwise occur every time a site’s code is executed. Such processes include many familiar processes, such as pop-ups, animations, or chat windows. Without a script, the user would have to reload the page to see these things again.

PHP becomes especially important if you plan to do custom development for WordPress . Although this is a rather specialized subdomain of web development, WordPress is nonetheless among the largest content development platforms on the market . Many custom WordPress plugins are built with PHP. You can still use plugins made by someone else, but if you want to modify them or create your own, you will need PHP.

How to get an absolute file path in Python

3 answers

izb By izb

Given a path such as "mydir/myfile.txt", how do I find the file"s absolute path relative to the current working directory in Python? E.g. on Windows, I might end up with:

"C:/example/cwd/mydir/myfile.txt"
877

Answer #1

>>> import os
>>> os.path.abspath("mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"

Also works if it is already an absolute path:

>>> import os
>>> os.path.abspath("C:/example/cwd/mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"

How to check if a path is absolute path or relative path in a cross-platform way with Python?

UNIX absolute path starts with "/", whereas Windows starts with alphabet "C:" or "". Does python have a standard function to check if a path is absolute or relative?

Answer #1

os.path.isabs returns True if the path is absolute, False if not. The documentation says it works in windows (I can confirm it works in Linux personally).

os.path.isabs(my_path)

How to join absolute and relative urls?

3 answers

I have two urls:

url1 = "http://127.0.0.1/test1/test2/test3/test5.xml"
url2 = "../../test4/test6.xml"

How can I get an absolute url for url2?

139

Answer #1

You should use urlparse.urljoin :

>>> import urlparse
>>> urlparse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"

With Python 3 (where urlparse is renamed to urllib.parse) you could use it as follow:

>>> import urllib.parse
>>> urllib.parse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"

Simply put and clear. Thank you for sharing. Learn PHP Or Javascript and other issues with DOM PHP module was always my weak point 😁. I am just not quite sure it is the best method
