To use debug or var_dump() in Smarty PHP, you can simply use the {debug} template function provided by Smarty. This function will display a detailed debug output of the variables within your template file.
Alternatively, you can use the var_dump() function directly in your PHP code to display detailed information about a variable. Simply add var_dump() before or after the variable you want to inspect, and the output will be displayed in the browser. Be sure to use this function for debugging purposes only, as it may not be suitable for production environments.

What is the best practice for using var_dump() in smarty php?
In Smarty PHP, var_dump() can be used for debugging purposes to display the contents and data type of a variable. However, it is not recommended to use var_dump() directly within a Smarty template file.
Instead, a better practice is to use var_dump() in the PHP file where the Smarty template is being assigned with values. For example, you can var_dump() the variable before assigning it to a Smarty template like this:
1 2 3 4 5 |
$myVariable = "Hello World"; var_dump($myVariable); $smarty->assign('myVariable', $myVariable); $smarty->display('myTemplate.tpl'); |
This way, you can debug the content of the variable in the PHP file and ensure that the correct data is being passed to the Smarty template. This helps to keep the template files clean and focused on the presentation logic.

What kind of information does var_dump() display?
var_dump() function in PHP is used to display structured information (type and value) of a variable. It displays data type, length, and value of a variable or array.
The information displayed by var_dump() includes:
- Data type of the variable (e.g. int, string, array, object)
- Length of the variable (for arrays and strings)
- Value of the variable or array elements
