Dear Frineds,


First I want to share a small joke with you about Reuseing Of Php Code

One new guy came for interview and I asked him that what is code reusability , then he replied is using the some code written by another person. then I became :rotfl: :bounce:


Reusing of php code is comes when We uses some classes and interfaces which consists of methods,

if my project requires a credit card validation in 20 pages,

[CODE]
creditcardvalidation.php
-----------------------------

Class CreditCardValidation
{


function validatecreditcard()
{
if(validcard)
{
return 1;
}





}

<?php

} // end of funciton


}// end of class

?>




creditcardvalidationusage1.php

<?php

include("crecreditcardvalidation.php");

$OBJCreditCardValidation= new CreditCardValidation();

$OBJCreditCardValidation->creditcardno=some number post of user

if($OBJCreditCardValidation->validatecreditcard())
{
echo "your card is valid";
}
else
{
echo "your card is not valid";
}


?>

<?php

include("crecreditcardvalidation.php");

$OBJCreditCardValidation= new CreditCardValidation();

$OBJCreditCardValidation->creditcardno=some number post of user

if($OBJCreditCardValidation->validatecreditcard())
{

do some online transactions

}
else
{
echo "your card is not valid";
}

creditcardvalidationusage3.php
-----------------------------------
<?php

include("crecreditcardvalidation.php");

$OBJCreditCardValidation= new CreditCardValidation();

$OBJCreditCardValidation->creditcardno=some number post of user

if($OBJCreditCardValidation->validatecreditcard())
{
store the creditcard number into database

}
else
{
echo "your card is not valid";
}


?>



so I write the code in one class and I am reusing the code in other files.
If I want to change the business loginc of validating the creditcard just I need to do the changes in the creditcardvalidation.php page only.
