title: If-else Statement
---
## Introduction
If/Else is a conditional statement where depending on the truthiness of a condition, different actions will be performed.  

> **Note:** The `{}` brackets are only needed if the condition has more than one action statement; however, it is best practice to include them regardless.

## If Statement

```
<?php

  if (condition) {
    statement1;
    statement2;
  }
```
> **Note:** The `else` statement is optional.
## If/Else Statement

```
<?php

  if (condition) {
    statement1;
    statement2;
  } else {
    statement3;
    statement4;
  }
```
> **Note:** `elseif` should always be written as one word.
## If/Elseif/Else Statement

```
<?php

  if (condition1) {
    statement1;
    statement2;
  } elseif (condition2) {
    statement3;
    statement4;
  } else {
    statement5;
  }
```
## Nested If/Else Statement

```
<?php

  if (condition1) {
      if (condition2) {
        statement1;
        statement2;
      } else {
        statement3;
        statement4;
      }
  } else {
      if (condition3) {
        statement5;
        statement6;
      } else {
        statement7;
        statement8;
      }
  }
```

## Multiple Conditions

Multiple conditions can be used at once with the "or" (||), "xor", and "and" (&&) logical operators.

For instance:

```
<?php

  if (condition1 && condition2) {
    echo 'Both conditions are true!';
  } elseif (condition 1 || condition2) {
    echo 'One condition is true!';
  } else (condition1 xor condition2) {
    echo 'One condition is true, and one condition is false!';
  }
```

## Ternary Operators

Another important option to consider when using short If/Else statements is the ternary operator.

Also there is an alternative syntax for control structures

  if (condition1):
    statement1;
  endif;
  else
    statement5;
