here all the questions I need only PHP Exercise 3 3 PHP Exercise 3 1 In this exercise, you will create a script that validates whether a credit card number contains only integers The script will remove dashes and spaces from the string After the dashes and spaces are removed, the script should reject the credit card number if it contains any other non numeric characters Create a folder named PHPEx3 on your h drive or on your home computer if you are completing this at home Create a new html document in your text editor Be sure to include all the appropriate html tags for a basic document Add id comments at the top containing your name, the date, and the words PHP Exercise 3 1 Add the following text and elements to the document body Validate Credit Card Add the following script section to the document body Declare a $CreditCard array that contains three values an empty string, a valid credit card number with numbers and dashes, and a credit card number with four initial uppercase letter Os $CreditCard array( , 8910 1234 5678 6543 , OOOO 9123 4567 0123 ) Add the following statements to iterate through each of the elements in the $CreditCardarray to determine if the element contains a value foreach ($CreditCard as $CardNumber) if (empty($CardNumber)) echo This Credit Card Number is invalid because it contains an empty string Add the following else clause to validate the credit card number The code uses str replace() functions to remove any dashes and spaces in the number Then, a nested if else statement checks whether the new value is numeric If the number is not numeric, a warning is displayed If the number is numeric, the modified credit card number is displayed in the Web browser else $CreditCardNumber $CardNumber $CreditCardNumber str replace( , , $CreditCardNumber) $CreditCardNumber str replace( , , $CreditCardNumber) if ( is numeric($CreditCardNumber)) echo Credit Card Number $CreditCardNumber is not a valid Credit Card number because it contains a non numeric character else echo Credit Card Number $CreditCardNumber is a valid Credit Card number Save the document as ValidateCreditCard php in the PHPEx3 folder PHP Exercise 3 2 In this exercise, you will create a script that uses comparison operators and functions to compare two strings to see if they are the same You will use this same technique in Lab 2 Create a new document in your text editor Be sure to include all the appropriate html tags for a basic document Add id comments at the top containing your name, the date, and the words PHP Exercise 3 1 Add the following text and elements to the document body Compare Strings Add the following script section to the document body In the script section, declare and initialize two string variables $firstString Geek2Geek $secondString Geezer2Geek Add the following if statement to the script section If both the $firstString and $secondString contain a value, the statements in the ifstatement execute The nested if statement uses the comparison operator ( ) to determine if both strings are the same If the strings are not the same, the elseclause uses the similar text()and levenshtein()functions to compare the strings if ( empty($firstString) empty($secondString)) if ($firstString $secondString) echo Both strings are the same else echo Both strings have similar text($firstString, $secondString) character(s) in common echo You must change levenshtein($firstString, $secondString) character(s) to make the strings the same At the end of the script section, add the following else clause, which executes if either the $firstString or the $secondStringcontains an empty value else echo Either the $firstString variable or the $secondString variable does not contain a value so the two strings cannot be compared Save the document as CompareStrings php in the PHPEx3 folder PHP Exercise 3 3 In this exercise, you will create a script that uses regular expressions to validate that an e mail address is valid for delivery to a user at example org For an e mail address to be in the correct format, only username or first last may appear before the symbol, and only example org or mail example org may appear after the symbol Create a new document in your text editor Be sure to include all the appropriate html tags for a basic document Add id comments at the top containing your name, the date, and the words PHP Exercise 3 3 Use Validate Local Address as the content of the element Add the following text and elements to the document body Validate Local Address Add the following script section to the document body In the script section, declare an $email array that contains five e mail addresses $email array( jsmith123 example org , john smith mail example org , john smith example org , john smith example , jsmith123 mail example org ) Add the following statements to iterate through each of the elements in the $emailarray to determine if it is in the correct format foreach ($email as $emailAddress) echo The email address $emailAddress if (preg match( (( A Za z d ) ( A Za z A Za z )) ((mail ) )example org$ i , $emailAddress) 1) echo is a valid e mail address else echo is not a valid e mail address Save the document as ValidateLocalAddress php in the Projects directory for Chapter 3 and upload the file to the server in the PHPEx3 folder Zip all three files in the PHPEx3 folder Upload the zipped file to the PHP Ex3 file upload folder
