php printf

Here is an example: round to two decimal places

Copy code The code is as follows:

$num1 = 21;
echo sprintf( "%0.2f",$num1)."
"; //Output 21.00
$num2 = 16.3287;
echo sprintf("%0.2f",$num2)."< br />"; //Output 16.33
$num3 = 32.12329;
echo sprintf("%0.2f",$num3)."
"; //Output 32.12
?>

Explain the meaning of %0.2f:

% means the starting character
0 means fill the space with 0
2 means there must be two digits after the decimal point
f means convert to floating point number

The difference between printf and sprintf

1. printf function:

int printf ( string format [, mixed args [, mixed ...]] )

Produces output according to format , which is described in the documentation for sprintf() .

Returns the length of the outputted string.

Format the text and then output it, such as:

Copy code The code is as follows:

$name="hunte";
$age=25;
printf("my name is %s, age %d", $name, $age);

2. sprintf function:
string sprintf ( string format [, mixed args [, mixed ...]] )

is a function that can return a value and can only have one parameter.

int print (string arg)

Outputs arg . Returns 1 , always.
