FAQ, PHP

PHP FAQ

  1. What does a special set of tags <?= and ?> do in PHP?
    – The output is displayed directly to the browser.
  2. What’s the difference between include and require?
    – It’s how they handle failures. If the file is not found by require(), it will cause a fatal error and halt the execution of the script. If the file is not found by include(), a warning will be issued, but execution will continue.
  3. I am trying to assign a variable the value of 0123, but it keeps coming up with a different number, what’s the problem?
    – PHP Interpreter treats numbers beginning with 0 as octal. Look at the similar PHP interview questions for more numeric problems.
  4. Would I use print “$a dollars” or “{$a} dollars” to print out the amount of dollars in this example?
    – In this example it wouldn’t matter, since the variable is all by itself, but if you were to print something like “{$a},000,000 mln dollars”, then you definitely need to use the braces.
  5. How do you define a constant?
    – Via define() directive, like define (“MYCONSTANT”, 100);
  6. How do you pass a variable by value?
    – Just like in C++, put an ampersand in front of it, like $a = &$b
  7. Will comparison of string “10″ and integer 11 work in PHP? – Yes, internally PHP will cast everything to the integer type, so numbers 10 and 11 will be compared.
  8. When are you supposed to use endif to end the conditional statement?
    – When the original if was followed by : and then the code block without braces.
  9. Explain the ternary conditional operator in PHP?
    – Expression preceding the ? is evaluated, if it’s true, then the expression preceding the : is executed, otherwise, the expression following : is executed.
  10. How do I find out the number of parameters passed into function?
    – func_num_args() function returns the number of parameters passed in.
  11. If the variable $a is equal to 5 and variable $b is equal to character a, what’s the value of $$b?
    – 100, it’s a reference to existing variable.
  12. What’s the difference between accessing a class method via -> and via ::?
    – :: is allowed to access methods that can perform static operations, i.e. those, which do not require object initialization.
  13. Are objects passed by value or by reference?
    – Everything is passed by value.
  14. How do you call a constructor for a parent class?
    – parent::constructor($value)
  15. What’s the special meaning of __sleep and __wakeup?
    – __sleep returns the array of all the variables than need to be saved, while __wakeup retrieves them.
  16. Why doesn’t the following code print the newline properly? <?php
    $str = ‘Hello, there.nHow are you?nThanks for visiting TechInterviews’;
    print $str;
    ?>
    Because inside the single quotes the n character is not interpreted as newline, just as a sequence of two characters – and n.
  17. Would you initialize your strings with single quotes or double quotes?
    – Since the data inside the single-quoted string is not parsed for variable substitution, it’s always a better idea speed-wise to initialize a string with single quotes, unless you specifically need variable substitution.
  18. How come the code <?php print “Contents: $arr[1]“; ?> works, but <?php print “Contents: $arr[1][2]“; ?> doesn’t for two-dimensional array of mine?
    – Any time you have an array with more than one dimension, complex parsing syntax is required. print “Contents: {$arr[1][2]}” would’ve worked.
  19. What is the difference between characters �23 and x23?
    – The first one is octal 23, the second is hex 23.
  20. With a heredoc syntax, do I get variable substitution inside the heredoc contents?
    – Yes.

If we remove the brackets and text for the sake of clarity, we’re basically left with a normal comment structure as follows:
      <!–

    6 :: How do we print the grid in Adobe Photoshop?


    Put the non printing grid on how you want it, then take a screen capture (alt + PrintScreen on PC) Open a new file, the size should be set as the size of the grab, and paste. Crop away everything (the background of the photoshop window, etc.)except for the image with grid on it…and print.

    7 :: Can you organize layers as in photoshop?

    Yes we can organize layes..
    For example you create a Ball in 1st layer and then in
    second layer you create the background. But you should lock
    all the layers and unlock the layer which u r working,
    because unlocked layers will be active always(active means,
    if u want to drage the ball, background layers also will be
    affected)

    Photoshop CS2 introduces a new type of layer called a Smart Object layer. Smart Objects are a little like symbols in Illustrator.

With smart objects, you can make multiple copies of a single object and all copies will be updated when one of the copies is edited ? but you can still apply layer styles and adjustment layers to the individual smart objects without affecting all copies, which provides for a lot of flexibility. Pixel-based smart objects also remember their original size and can be transformed multiple times without loss.

These aerospace engineers will be responsible to conduct stress analysis on metallic and composite structures. NASTRAN, IDEAD, Oracle and PATRAN proficiency level is required. Their duties also include on aircraft which are metallic and composite structures. This includes and understanding of control surface stiffness and loop calculations, finite element modeling (FEM), fatigue testing requirement and analysis.
