PHP is the acronym for "PHP: Hypertext Preprocessor". PHP is a server-side scripting programming language. It is now widely used in the world. Because, it is free, easy to understand, coding and editing. PHP is a very acceptable and popular language for the development of RDBMS based online Application software. PHP is free and can be downloaded and used for application software or website development.

The PHP file extension is ".php". Example- salary.php, lottery.php

PHP supports a wide range of databases like MySQL, Oracle, PostgreSQL, SQLite etc. Any professional can download PHP's  latest version install it.

PHP is very compatible with webserver software Apache and IIS. Apache is a free web server and is used in the Linux environment. IIS is the available windows OS. So, IIS is the product of Microsoft Corporation. Both Apache and IIS is very popular in the world and 95% of user use them as webserver.

PHP is the middleware programming script that works between Apache / IIS webserver and Database. PHP is capable to embedded with HTML.

There is a friendship between PHP and c programming. Programming syntax is nearer. If anybody knows c then PHP is easy for him/her. If anybody knows PHP then c is easy to understand for him/her.

Practice 1: PHP installation test

// To test whether PHP installed properly or not

?? View all Global variables

<?php

               phpinfo();

?>

Practice 2: Ascii to char

/*

 chr() is used for ascii to char convert

 ord() is used for char to ascii convert

 book page 195

 */

<?php

$tnum=500;

for($i=0;$i<=$tnum;$i++)

               {

               echo "ASCII Value is : ".$i." Corresponding character value is :    ".chr($i)."<br>";

               }

?>

 Practice 3: for loop to generate two digit numbers

// generate a list of possibilities for two digit numbers consisting of numbers 0 to 5

<?php

echo"<br>";

echo"<br>";

for($i=0;$i<6;$i++)

{

               for($j=0;$j<6;$j++)

               {

                              echo$i.$j." ";

               }

               echo"<br>";

}

?>

 Practice 4: Find Squire  value of given input

// Find Squire and Qube Value

<?php

for ($i=0,$j=0; $i<9,$j<9; $i++,$j++)

              

               {

                              echo "Original valuse : ".$i."               Squire valuse : ".$i*$j."              Qube value : ".$i*$i*$i;

                              echo "<br>";

               }

?>

Practice 5: Generate lottery number using for loop

<?php

$tot_output=255;

for($i=1;$i<=$tot_output;$i++)

{

// put random value at an array

$tt[$i]=rand(500,999);

}

// Output print

echo " ICB Recruitment test 2009";

echo "<br>";

echo " Random number for Data entry Control Operator Post";

echo "<br>";

echo " --------------------------------------------------";

echo "<br>";

echo "<br>";

for($k=1;$k<=$tot_output;$k++)

               {

               echo $tt[$k]."<br>";

               }

?>

 Practice 6: Making results using array, foreach,  and if else if

// Write a program that will generate grade and gives statistics on the basis of marks.

<?php

$dist=0;

$frst=0;

$scnd=0;

$thrd=0;

$fail=0;

$marks=array(1,67,82,23,37,57,97,80,9,0,99,45,78,93,28,39,85);

foreach($marks as $mark)

{

               if($mark>=80)

               {

               echo " The result for $mark marks is : Distinction.<br>";

               $dist++;

               }

               else if ($mark>=60)

               {

               echo " The result for $mark marks is : First Class.<br>";

               $frst++;

               }

               else if ($mark>=45)

               {

               echo " The result for $mark marks is : Second Class.<br>";

               $scnd++;

               }

               else if ($mark>=33)

               {

               echo " The result for $mark marks is : Third Class.<br>";

               $thrd++;

               }

               else

               {

               echo " The result for $mark marks is : Fail.<br>";

               $fail++;

               }

}

echo " <br><br>";

echo "Result statistics <br><br>";

echo "Total Distinction got    : $dist<br>";

echo "Total First Class got    : $frst<br>";

echo "Total Second Class got  : $scnd<br>";

echo "Total Third Class  got   : $thrd<br>";

echo "Total Failed             : $fail<br>";

?>

Practice 7:  Write a PHP program that generates the HASH value of a given text

// sha stands for secured hash algorithm

<?php

// sha stands for secured hash algorithm

echo strtoupper("40 characters output"."<br><br>");

print sha1("Rashid")."<br><br>";

print sha1("mamun")."<br><br>";

print sha1("Mamun")."<br><br>";

print sha1("md. abdur rashid")."<br><be>";

?>

The following output will see on the screen-

40 CHARACTERS OUTPUT

9bdb930b6eccb89f8d95bd9a34b4bc459bed3ff7

f87095637ed82c1e6d131b714674b30174b7e83c

5dfc4cc5f56bd0184409c2e4d4354dfe920cb89a

Practice 8: Write a PHP program that generates the HEXA value of a given text

// Give 32 characters hexadecimal output. 

// md stands for message digest

// md5() function gives the 128 bit 'fingerprint' or 'message digest' of the given input. This output can be used in digital signature.

<?php

echo strtoupper("32 characters output"."<br><br>");

print md5("Rashid")."<br><br>";

print md5("mamun")."<br><br>";

print md5("Mamun")."<br><br>";

print md5("md. abdur rashid")."<br><br>";

?>

The following output will see on the screen:

32 CHARACTERS OUTPUT is 

12aaedf2544497666587758bba8a3838

c8e36a853fe91f3a4a3c4d739e830139

Practice 9: Write a PHP program that sum of a given input

// create a function that make sum

<?php

$var1=295;

function mysum()

{

global $var1,$var2,$total;

$total=$var1+$var2;

return($total);

}

$var2=89;

mysum();

echo "<br>";

echo "<br>";

echo " Total calculated value  :  ".$total;

echo "<br>";

$grant_total=$total+500;

echo " Total grant value       :  ".$grant_total;

/*

In php global variables must declare inside the function

*/

Program Output:

Total calculated value: 384
Total grant value: 884

Practice 10: Write a PHP program to find the salary

// create a function that makes your monthly salary

<?php

function salary($basic)

{

$hrent=$basic*0.50;

$medical=900;

$pf=$basic*0.10;

$gi=200;

$car=100;

$ssss=$basic+$hrent+$medical-$pf-$gi-$car;

return($ssss);

}

$bb=0;

$basic=25000;

$total_salary=salary($basic);

echo "<br>";

echo "<br>";

echo "<br>";

echo " Total salary encountered    :  ".$total_salary;

Program output:

Total salary encountered: 35600
