Conditional statements in PHP include
PHP conditional statements, like if, else, elseif, and switch, control code execution based on specified conditions, enhancing code flexibility and logic flow.
if statement:
PHP if statement executes a block of code if a specified condition is true.
if (condition) {
// Code to execute if condition is true
}
else statement:
PHP else statement executes a block of code if the condition of the preceding if statement evaluates to false.
if (condition) {
// Code to execute if condition is true
} else {
// Code to execute if condition is false
}
else if statement:
PHP else if statement allows you to evaluate multiple conditions sequentially and execute the corresponding block of code if any condition is true.
if (condition1) {
// Code to execute if condition1 is true
} elseif (condition2) {
// Code to execute if condition2 is true
} else {
// Code to execute if both condition1 and condition2 are false
}
switch statement:
PHP switch statement provides an alternative to multiple elseif statements by allowing you to test a variable against multiple possible values and execute different blocks of code accordingly.
switch (expression) {
case value1:
// Code to execute if expression equals value1
break;
case value2:
// Code to execute if expression equals value2
break;
// More cases can be added as needed
default:
// Code to execute if expression doesn't match any case
}
