Debug
Prisma PHP provides a simple and user-friendly way to debug your application. With Prisma PHP, you can easily debug your code, identify and fix issues, and optimize your application for performance. Prisma PHP makes it easy to work with your code, allowing you to focus on building your application instead of spending time on debugging complex issues.
Using the echo
statement in your PHP code is a common way to debug your application. When you use the echo statement, it will print the output on the top of your screen. The echo message will be displayed when the tab or the page is refreshed or reloaded. This approach is particularly useful when the echo statement is outside of any function call. The downside is that this will not show when any dynamic request is made using the onclick
event in the button or any other event.
<?php
echo "Hello, World!";
?>
Using the echo
statement with HTML
tags in your PHP code is a powerful way to debug your application. When you use echo with HTML tags, the output will be displayed on the screen when the tab or the page is refreshed or reloaded. This allows you to easily visualize and inspect the data being echoed, even if the page makes a dynamic request using the onclick
event in the button or any other event.
<?php
echo "<p>Hello, World!</p>";
?>
Debugging a function
call with an event click
or any other event is a common practice. You can use the echo statement to display the output of the function on the screen. This allows you to easily inspect and analyze the data being printed.
<?php
function showMessage($data)
{
echo "showMessage called";
echo "<pre>";
print_r($data);
echo "</pre>";
}
?>
<button onclick="showMessage('Hello, World!')">Click Me</button>
Note: When a function is called and the echo statement does not contain any HTML tags, the output will be assigned to a div
tag that contains all the echo output. This is the difference between an echo message without any HTML tags outside of a function call and inside of a function call.
Using the return
statement in your PHP code is another way to debug your application. When you use the return statement, it will return the data to the JavaScript function specified in the pp-after-request
attribute of the button tag. This allows you to easily debug the returned data by displaying it in the developer console. By using this approach, you can effectively debug the data returned from the function you have called.
<?php
function showMessage($data)
{
return $data;
}
?>
<button onclick="showMessage('Hello, World!')" pp-after-request="getTheReturnData" >Click Me</button>
<script>
function getTheReturnData(data)
{
console.log(data);
}
</script>
When you use the return
statement, the data that is returned will be converted to JSON and included in the response. It can then be accessed by the JavaScript function specified in the pp-after-request
attribute of the button tag. This allows you to easily debug the returned data by displaying it in the developer console. By using this approach, you can effectively debug the data returned from the function you have called.
