Introduction to the debug console
Let’s check that the name “Leopom chandelier” has actually been written to the variable $title. The debug console will help us with this.
The debug console was specially developed by Muffin’s studio for displaying the output of commands and text prompts. Developers can use it to quickly debug their programs. In our interface, the console is on the right under the mini browser.
Since PHP does not have a command that can output information to the console for debugging purposes, we use the special command muffin_log -- another amazing custom development by our studio! Unfortunately, it is not part of the PHP language, which means that this command will not work outside of our studio.
We indicate the name of the variable whose value we want to see in parentheses. The command will output, that is, write, the value of the variable to the console.
// We declared a variable with the name $product and the value 'chandelier'
$product = 'Chandelier';
// We want to view the value of the variable.
muffin_log($product);
// Outputs: "Chandelier"Now let’s output the value of our variable $title to the debug console.
