The vprintf() function in PHP is used to output a formatted string. It works in the same way as printf(), except that the arguments are passed in an array rather than as separate parameters.


Here is the syntax of the vprintf() function:

vprintf(format, args_array)

The first argument is a string that contains placeholders for the values that will be inserted into the string. These placeholders begin with a percent (%) character and are followed by a letter that specifies the type of data that will be inserted.

The second argument is an array of values that will be inserted into the placeholders. The values must be in the order that they appear in the string.


Here is an example of how to use vprintf():


$values = ['apple', 'banana', 'orange'];
vprintf('I like %s, %s, and %s.', $values);

This will output:

I like apple, banana, and orange.

In this example, the %s placeholders are replaced with the values in the $values array.

The vprintf() function is useful when you have a variable number of arguments that you want to format and output.
