Why PhP logic is very hard.

Question

php team make the php is easy like concate string and case insensitive and also js is have small hard like

if("1e3" == "1000")
it's true 😢 😢

Answer 1

Yousef10 This all the concept

== Equal $x == $y Returns true if $x is equal to $y
=== Identical $x === $y Returns true if $x is equal to $y, and they are of the same type
!= Not equal $x != $y Returns true if $x is not equal to $y
<> Not equal $x <> $y Returns true if $x is not equal to $y !== Not identical $x !== $y Returns true if $x is not equal to $y, or they are not of the same type
> Greater than $x > $y Returns true if $x is greater than $y
< Less than $x < $y Returns true if $x is less than $y
>= Greater than or equal to $x >= $y Returns true if $x is greater than or equal to $y
<= Less than or equal to $x <= $y Returns true if $x is less than or equal to $y

Answer 2

And 1e3 is a “scientific notation”of numbers (5e3 is 5000, 1.2e5 is 120000, 0.7e2 is 70, can you see a logic how are those numbers notated?)

Answer 3

if("05" =="5")
? :000

Answer 11

Yousef10 you're scaring me away from learning PHP,why?

Answer 12

if (0) isn’t “true”. Perhaps You have seen a question where second option (else) is “echo 01;” but when PHP outputs numbers it drops first (leading) zeroes... (So it looks like first option “echo 1;” is fired ;-))

Answer 13

You see, the numbers after “e” means how many position in decimal numbers decimal point (that “dot”in number) is moved... ...e3 means that you are multiplying the part before “e” and 1000 (three zeroes ~ three position in decimal number...)

Answer 14

:-D “helfull” ;-) 😂

Answer 15

(yep difference between programmind languages is a kind of hell. While I try to study a bunch of them simultaneously [yes, I know that it’s a big mistake...] it makes my brain exploding sometimes 😊)

Answer 16

Andrew Harchenko (Tomsk) Can You Answer For The Comment [7] please ?

Answer 17

Sadaam Linux You Are Never Lost In Challenge :D ! Nice :) Continue ^_^

Answer 18

In that given screenshot you are (ok, PHP is) replacing variables $a, $b and $c in a string in _double quotes_ with their values which are 1, 1 and 1 (types don't matter here when we are just outputting 'em) and that's all. (No one is going to make PHP evaluate any arithmetical expressiin in strings, only substitutions of variables are done [or we won't be able to output a string "1+1" ☺])

Answer 19

no don't lost in challenge plz :)
