Palindrome an other script with using functions.

Palindrome an other script with using functions. Previous Palindrome Script was coded without using any function. In this function 3 methods are used,

1. str_split() function
2. var_dump() function
3. implode() function

User will input any value consist on 5 digits, then str_split() will split your word / sentence to array. And 2nd var_dump() function will show the value, type of array, then implode() function is used to combine the value. 

check this code. try it
My friend Dan Edge helped me in it.
I thank to him.

Write an application that reads in a five-digit integer and determines whether it’s a palindrome. If the number is not five digits long, display an error message and allow the user to enter a new value.

I used many functions in this script. like Mod, Divide, Array Value Assigning, Float Function, then I used simple If .. else.. If conditional statement, and if within in statement.  
(Palindromes) A palindrome is a sequence of characters that reads the same backward as
forward.
For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and
11611.

Try this code. I hope you will learn from it.

Write a script for Square of Asterisks?

I used nested loop in this script for creating square of Asterisks. I used for loop 1st then i used while loop within for loop and then I used if conditional statement to create break.
Try this code.

 <?PHP  
      $inputs = array();  
      if (isset($_POST['submit'])) { //to check if the form was submitted  
           $value = isset($_POST['input0'])? $_POST['input0'] : null;  
           for($count = 1; $value != null; $count++){  
                array_push($inputs, $value);  
                $value = isset($_POST['input'.$count])? $_POST['input'.$count] : null;  
           }  
      }  
      var_dump($inputs);  
 ?>       
 <form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">  
   <!-- to take multiple inputs copy the below line and change name="input" attribute -->

   for ($a=1 ; $a<= $inputs[0]; $a++)  
   {  
   $x = $inputs[0];  
   $y = 1;  
   while ($y <= $x)  
   {  
     echo "*";  
     if($y==$x)

Write a script that prompts the user to enter the size of the side of a square and then displays a hollow square of that size made of asterisks. Your script should work for squares of all side lengths between 1 and 20.

For making Hollow Square of Asterisks, I need to use 3 times for loop. It is easy ; check this script.
You should try it.
User will enter a value and will get exact numbers of Asterisks Hollow Square:

(Validating User Input) For any input, if the value entered is other than 1 or 2, keep taking input until the user enters a correct value.

Assignment is about to show that number is 1 and 2 or digit.
I used if else if statement here. and find great function.
Note : use this code. and try from different ways.

Find Greatest Number from 10 inputs : PHP Assignment

I used input bar code in this assignment, which my teacher gave me to use. I used 10 input bars with different names. Then I used while loop and if conditional statement within loop to make this assignment successful.

Write a script which prints all the odd numbers. Output: 1 3 5 7 9 …

I used while loop in this script with if conditional statement within while. Here I used Mod (%) in if and get results till 55. try this code.

Write a script that calculates and prints the sum of the integers from 1 to 10. Use a while statement to loop through the calculation and increment statements. The loop should terminate when the value of x becomes 11.

I used ; while loop for it and used if condition within while loop and add break for 1st loop.
code is given bellow understand it.
