# PHP User Defined Functions
In this [article](https://yourviews.mindstick.com/view/81489/kashmir-now-after-an-year-of-abrogation-of-article-370) I will show you how to create your own [function](https://www.mindstick.com/articles/43970/purchase-suitable-wedding-dresses-for-your-wedding-function). To keep the [script](https://www.mindstick.com/interview/2280/is-jquery-replacement-of-java-script) from being executed when the [page](https://yourviews.mindstick.com/view/83591/the-complete-guide-page-speed-optimisation-and-seo) loads, you can [put](https://answers.mindstick.com/qa/37572/should-schools-put-tracking-devices-in-students-id-cards) it into a function. A function will be executed by a call to the function. You may call a function from anywhere within a page.\
Let’s we have an example, how to implement [PHP](https://www.mindstick.com/articles/12149/php-constant-and-php-variables) functions.
##### Syntax:
```
function function_Name() { code to be executed; }
```
Note: The function [name](https://answers.mindstick.com/qa/38468/name-the-bollywood-actor-who-has-been-named-by-the-indian-olympic-association-as-the-country-s-goodwill-ambassador-representing-the-indian-contingent-at-the-2016-rio-olympics) can start with a letter or underscore (not a number).
**Example:** Creating function with no [parameter](https://www.mindstick.com/blog/450/parameter-class-in-c-sharp)
```
Function Test "; // Calling function AdditionNum(); ?>
```
##### Output:
Example: Creating function with parameter.

##### Syntax:
```
function functionName(param1, param2,...) { code to be executed; } Function with parameter "; // Calling function AdditionNum(12,13); ?>
```
##### Output:
