Study Notes
Conditional Statements
- Conditional statements are useful for writing logic making code
- If statements execute some code if one condition is true
- If...else statements execute some code if a condition is true and another code if that condition is false
- If...elseif...else statements execute different codes for more than two conditions
Switch Statements
- PHP conditional statements are implemented by the following: if, if...else, if...elseif...else, and switch statements
- The switch statement is used to perform different actions based on different conditions
- Syntax for switch statement: switch (n) { case label 1: code to be executed if n=label 1; break; ... default: code to be executed if n is different from all labels; }
PHP Program Example
- Example program to check student grade based on marks: A+, A, B, C, D grade or fail
- User input: 76, Output: D grade
- If statements can be used to check conditions and execute specific code blocks based on the conditions
Conditional Statement Syntax
- If statement syntax: If( 1st condition) { Execute statement(s) if condition is true; } { elseif( 2nd condition )Execute statement(s) if 2nd condition is true; } Else{ Execute statement(s) if both conditions are false; }
