Replace the percent (%) sign by a variable passed as an argument: $number = 9; $str = “Beijing”;
Using the format value %f: $number = 123; $txt = sprintf(“%f”,$number);
Use of placeholders: $number = 123;
A demonstration of string specifiers: $str1 = “Hello”;
What are formatting strings in PHP?
An optional padding specifier that indicates which character should be used to pad the results to the correct string size.
An optional alignment specifier that indicates whether the results should be left- justified or right-justified.
What is 2f PHP?
2f in the format specifier is for the filling length. Per default sprintf uses the space character. There’s 16 spaces before the number. The float takes up 4, and the fill length was set to 20 for instance.
What does %s mean in PHP?
That means it juggles variable types as needed. In sprint it means that if you pass a “string” as argument for a number placeholder (%d), that string will be converted to a number (int, float…)
What is difference between printf () and sprintf () in PHP?

Why sprintf is used in PHP?
Using sprintf() is much cleaner and safer to format your string. For example when you’re dealing with input variables, it prevents unexpected surprises by specifying the expected format in advance (for instance, that you’re expecting string [ %s ] or the number [ %d ]).
Can printf be used in PHP?
