Hi,

Instead of having the code on Word I decided to put all the code in the
file index.php.

Normally I would have a framework and using OO, however for this exercice
I dediced just to have one file.

So you can run in the terminal: php index.php # [params]
Example:

For question 1:
php index.php 1

For question 2:
php index.php 2 5

For question 3:
php index.php 3 4

For question 4:
php index.php 4 10 2,4,5,8,10,20,30

In this case you are executing function 4, sending 10 as the number to look up
and you ared sending the array: 2,4,5,8,10,20,30

For question 5, 6 and 7:
php index.php 5
php index.php 6
php index.php 7

For question 8:
php index.php 8

For question 9:
php index.php 9 16

For question 10:
php index.php 10

For question 11:
php index.php 11 good
php index.php 11 'even better'

You can send an string with more than 1 word using ''

For question 12:
php index.php 12

For question 13:
php index.php 13

Please open the file lightbox.html

For question 14:
php index.php 14

You can paste this code in a JS terminal:

str_1 = "------- The quick brown fox jumps over the lazy dog -------";

function custom_str_replace(str){
return str.replace("The quick brown fox jumps over the lazy dog","The1 quick2 brown3 fox4 jumps5 over6 the7 lazy8 dog9");
}

str_2 = custom_str_replace(str_1);

For question 15:
php index.php 15
