Was thinking of a primary school classmate, typed in the name and returned a lot of result of various people, wonder what shows up now if I type in my Chinese name? (Yes I have done it before, years ago) And results are some PHP Dokuwiki plugins I wrote 9 years ago! Like… https://www.dokuwiki.org/plugin:tablemath, and this https://www.dokuwiki.org/plugin:autoincludeindex,… Read More »
After been through some tutorials of Laravel, it’s quite obvious that Django pwns Laravel in any day (if you know Python). There are a lot of manual process in Laravel that Django would have made it so easy, note this is not the same “black magic” that Laravel provides. Python vs PHP Since I am… Read More »
During the last day of Christmas break I’ve spent a few hours trying to pick up Laravel again, from the beginning. I remember I blogged about Laravel back in 2016 (time flies!), and reading them again, I am surprised that what I thought back in 2016 still applies today. Today I am going to talk… Read More »
I am not sure who else is doing this but I have a static typed language background and I tend to write code in static type style. Don’t assign different value types to the same variable Let’s see what dynamic type in the simplest form in Python:
|
1 2 3 |
variable_a = True if variable_a: variable_a = 'Result' |
While this is perfectly legitimate, but it’s… Read More »
PHP and Python both are dynamic typed language, so there is no point the discuss anything related in this aspect. Exception is first class citizen
|
1 2 3 4 |
try: a = 1 / 0 except: print 'Caught' |
Prints ‘Caught’ Let’s look at PHP:
|
1 2 3 4 5 6 |
try{ $a = 1 / 0; }catch (Exception $e){ print "Caught"; } I cannot believe by default this still gives me PHP Warning: Division by zero |
Better functions Imagine you can write functions like this
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
def marry(man, woman): ... marry('John', 'Julie') marry(woman='Julie', man='John') def party(*args): for person in args: print person party('John') party('John', 'Ben', ...) def save(name, *kwargs): data = {'name': name} data.update(kwargs) write_to_db(data) save('John') save('John', gender='male', birthday='01/01/1970') |
Short-lived vs Long-lived Almost all PHP scripts are short-lived, including most frameworks, which… Read More »
Project Structure After setting up the quickstart project, I feel the project structure is quite different to Django. In Django a lot of code are organised in “app” domain, but it seems to me that multi-app is not something out-of-the-box in Laravel: https://laracasts.com/discuss/channels/general-discussion/laravel-5-multi-app-or-modular-applications Instead, it seems the apps in Django is more similar to the… Read More »
It appeared to me that “Laravel” is kind of similar to Django in the way of implementation concept, so this is my obvious choice. I did a google search “Laravel for Django developers” and got pretty much nothing useful, sure, who would have move back to PHP from Python? I think this only happens in… Read More »
