    2. 2. TRIVUz AcademyRecap PF01 TRIVUz Academy
    3. 3. We learn before We Define Computer & Program Define Computer Programming Programming Process Programming Language Inputs & Outputs Define Logical Processing Variables Data TypesProgramming Fundamentals TRIVUz Academy www.trivuzacademy.com
    4. 4. We will learn today Conditional Statement If… then … else Switch statement OperatorsProgramming Fundamentals TRIVUz Academywww.trivuzacademy.com
    5. 5. Conditional Statement• Conditional statements are the set of command used to perform different actions base on different conditions• In PHP we have the following conditional statements: • if • if else • else if • switch TRIVUz Academy
    6. 6. If statement execute some code only if statement is trueTRIVUz Academy
    7. 7. If…TRIVUz Academy
    8. 8. If… ifTRIVUz Academy
    9. 9. If… if (conditional)TRIVUz Academy
    10. 10. If… if (conditional) {TRIVUz Academy
    11. 11. If… if (conditional) { // statement to be executedTRIVUz Academy
    12. 12. If… if (conditional) { // statement to be executed }TRIVUz Academy
    13. 13. If… Example: if ($math < 33) { $result = “Failed!”; }TRIVUz Academy
    14. 14. If…else statement execute some code if statement is true and some other code if statement is falseTRIVUz Academy
    15. 15. If…else… if (conditional) { // statement if true }TRIVUz Academy
    16. 16. If…else… if (conditional) { // statement if true } elseTRIVUz Academy
    17. 17. If…else… if (conditional) { // statement if true } else { // statement if falseTRIVUz Academy
    18. 18. If…else… if (conditional) { // statement if true } else { // statement if false }TRIVUz Academy
    19. 19. If…else… Example: if ($math < 33) { $result = “Failed!”; } else { $result = “Passed!”; }TRIVUz Academy
    20. 20. If…else if…else statement execute some code if statement is true And some other code if statement is falseTRIVUz Academy
    21. 21. If…else if…else if (conditional) { // statement if true } else if (conditional){ // statement if false and else if true } else { // statement if all false }TRIVUz Academy
    22. 22. If…else if…else if (conditional) { // statement if true } else if (conditional){ // whichever matches first } else if (conditional){ // whichever matches first } else if (conditional){ // whichever matches first } else if (conditional){ // whichever matches first } else { // statement if all false }TRIVUz Academy
    23. 23. If…else if…else Example: if ($avg > 100) { $grade = "Invalid"; } else if ($avg > 90 and $avg < 100 ) { $grade = "A+"; } else if($avg > 80 and $avg < 90) { $grade = "A"; } else { $grade = "F"; }TRIVUz Academy
    24. 24. switch statement Select one of many block of code to executeTRIVUz Academy
    25. 25. switch switchTRIVUz Academy
    26. 26. switch switch (value)TRIVUz Academy
    27. 27. switch switch (value) {TRIVUz Academy
    28. 28. switch switch (value) { case 1: // some code to executeTRIVUz Academy
    29. 29. switch switch (value) { case 1: // some code to execute break;TRIVUz Academy
    30. 30. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break;TRIVUz Academy
    31. 31. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break; default: // nothing matches, do itTRIVUz Academy
    32. 32. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break; default:  similar to else in if..else // nothing matches, do itTRIVUz Academy
    33. 33. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break; default: // nothing matches, do it }TRIVUz Academy
    34. 34. switchswitch (n){case label1: code to be executed if n=label1; break;case label2: code to be executed if n=label2; break;default: code to be executed if n is different from both label1and label2;} TRIVUz Academy
    35. 35. switch<html><body><?php switch ($x) { case 1: echo "Number 1"; break; case 2: echo "Number 2"; break; case 3: echo "Number 3"; break; default: echo "No number between 1 and 3"; }?></body> TRIVUz Academy</html>
