PHP Solved Practical Slips
Write a PHP script for the following: Design a form to accept a string. Write a function to count the total number of vowels (a,e,i,o,u) from the string. Show the occurrences of each vowel from the string. Check whether the given string is a palindrome or not, without using built-in function. (Use radio buttons and the concept of function. Use ‘include’ construct or require stmt.)

Write a PHP script for the following: Design a form to accept two strings from the user. Find the first occurrence and the last occurrence of the small string in the large string. Also count the total number of occurrences of small string in the large string. Provide a text box to accept a string, which will replace the small string in the large string. (Use built-in functions)

Write a PHP script for the following: Design a form to accept two numbers from the user. Give options to choose the arithmetic operation (use radio buttons). Display the result on the next form. (Use the concept of function and default parameters. Use ‘include’ construct or require stmt).
Write a PHP script for the following: Design a form to accept two strings from the user. Find whether the small string appears at the start of the large string. Provide a text box to accept the string that will replace all occurrences of small string present in the large string. Also split the large string into separate words. (Use regular expressions)

Write a PHP script for the following: Design a form to accept two strings. Compare the two strings using both methods (= = operator &strcmp function). Append second string to the first string. Accept the position from the user; from where the characters from the first string are reversed. (Use radio buttons)
Write a menu driven PHP program to perform the following operations on an associative array: i. Display the elements of an array along with the keys. ii. Display the size of an array iii. Delete an element from an array from the given index. iv. Reverse the order of each element’s key-value pair.[Hint: use array_flip()] v. Traverse the elements in an array in random order [[Hint: use shuffle()].
Write a menu driven PHP program to perform the following operations on associative arrays: a) Sort the array by values (changing the keys) in ascending, descending order. b) Also sort the array by values without changing the keys. c) Filter the odd elements from an array. d) Sort the different arrays at a glance using single function. e) Merge the given arrays. f) Find the Union, intersection & set difference of two arrays.

Write class declarations and member function definitions for an employee(code, name, designation).Design derived classes as emp_account(account_no, joining_date) from employee and emp_sal(basic_pay, earnings, deduction) from emp_account. Write a menu driven PHP program a) to build a master table b) to sort all entries c) to search an entry d) Display salary.
