- What does "=>" mean in PHP?
 Top Answer
 Answered Jan 20, 2015 · 135 votes
 => is the separator for associative arrays. In the context of that foreach loop, it assigns the key of the array to $user and the value to $pass.
 Example:
 $user_list = array( 'dave' => 'apassword', 'steve' => 'secr3t');foreach ($user_list as $user => $pass) { echo "{$user}'s pass is: {$pass}\n";}// Prints: // "dave's pass is: apassword"// "steve's pass is: secr3t"
 
 Note that this can be used for numerically indexed arrays too.
 Example:
 $foo = array('car', 'truck', 'van', 'bike', 'rickshaw');foreach ($foo as $i => $type) { echo "{$i}: {$type}\n";}// prints:// 0: car// 1: truck// 2: van// 3: bike// 4: rickshaw

- What does @ mean in PHP?
 Top Answer
 Answered Apr 19, 2011 · 72 votes
 The @
 
 operator tells PHP to suppress error messages, so that they will not be shown.
 For instance, using:
 $result = mysql_query("this is an invalid query");-
 
 would result in a warning being shown, telling you that the MySQL query is invalid, while
 $result = @mysql_query("this is still an invalid query");-
 
 would not.
 Note, however, that this is very bad programming practice as it does not make error disappear, it just hides them, and it makes debugging a heck of a lot worse since you can't see what's actually wrong with your code.
 Instead of using @, you should disable error_reporting
 
 and display_errors
 
 just display_errors in php.ini

- What does ":" mean in PHP?

 It's called an Alternative Syntax For Control Structures. You should have an endwhile; somewhere after that. Basically, it allows you to omit braces {} from a while to make it look "prettier"...
 As far as your edit, it's called the Ternary Operator (it's the third section). Basically it's an assignment shorthand.
 $foo = $first ? $second : $third;
 
 is the same as saying (Just shorter):
 if ($first) { $foo = $second;} else { $foo = $third;}

 There is an example listed in the documentation for while
 
 that explains the syntax:
 Like with the if statement, you can group multiple statements within the same while loop by surrounding a group of statements with curly braces, or by using the alternate syntax:
 while (expr): statement ...endwhile;
 
 An answer over here explains it like this:
 This (:) operator mostly used in embedded coding of php and html.
 Using this operator you can avoid use of curly brace. This operator reduce complexity in embedded coding. You can use this(:) operator with if, while, for, foreach and more...
 Without (:) operator
 <body><?php if(true){ ?>This is just test<?php } ?></body>
 
 With (:) operator
 <body><?php if(true): ?>This is just test<?php endif; ?></body>

 It's the 'Scope Resolution Operator'.
 The Scope Resolution Operator (also called Paamayim Nekudotayim) or in simpler terms, the double colon, is a token that allows access to static, constant, and overridden properties or methods of a class.
