In this tutorial you'll learn how to write decision-making code using if...else...elseif statements in PHP.Like most programming languages, PHP also allows you to write code that perform different actions based on the results of a logical or comparative test conditions at run time. First have a look at the demo followed by a little description: I'd like to try to improve on them:The fact that this ambiguity even exists makes a lot of programmers just always use Some languages like Perl use this kind of construct frequently in a format similar to this:This would theoretically assign the database connection to Some languages that allow for this construct straight out forbid assignments in conditional/logical statements (like Python) to remove the amiguity the other way round.PHP went with allowing both, so you just have to learn about your two options once and then code how you'd like, but hopefully you'll be consistent one way or another.
