PHP vsprintf() Function

PHP vsprintf() Function

The vsprintf() function in PHP returns a formatted string. This function accepts an array of arguments.

Syntax

vsprintf ( string $format , array $args )

Parameter

format(required)- This parameter specifies the string and how to format the variables in it.

The conversion specification of this parameter follows the given prototype: %[flags][width][.precision]specifier.

Flags

Flag	Description
-	Left-justify within the given field width and by default, it follows the right justification
+	It signifies the prefix positive numbers with a plus sign (+). By default, only negative is prefixed with a negative sign.
(space)	It pads the result with spaces. This is the default.
0	It only left-pads numbers with zeros. With “s” specifiers this can also right-pad with zeros.
(char)	It pads the result with the character (char).

Width

It signifies an integer that states how many characters (minimum) this conversion should result in.

Precision

• e, E, f and F specifiers: The number of digits to be printed after the decimal point (by default, it is 6).
• g and G specifiers: The maximum number of significant digits to be printed.
• s specifier: It acts as a cutoff point, setting a maximum character limit to the string.

If the period is specified without an explicit value for precision, 0 is assumed.

Specifiers

Specifier	Description
%	It represents a literal percent character, and no other argument is required.
B	In this, the argument is treated as an integer and presented as a binary number.
C	In this, the argument is treated as an integer and presented as the character with that ASCII.
D	In this, the argument is treated as an integer and presented as a (signed) decimal number.
E	In this, the argument is treated as scientific notation. The precision specifier stands for the number of digits after the decimal point.
E	It is like the “e” specifier, but it uses the uppercase letter.
F	The argument is treated as a float and presented as a floating-point number (locale aware).
F	The argument is treated as a float and presented as a floating-point number (non-locale aware).
G	It represents a general format.
G	Unlike the “g” specifier but it also uses E and F.
O	In this, the argument is treated as an integer and presented as an octal number.
S	In this, the argument is treated and presented as a string.
U	In this, the argument is treated as an integer and presented as an unsigned decimal number.
X	The argument is treated as an integer and presented as a hexadecimal number (with lowercase letters).
X	The argument is treated as an integer and presented as a hexadecimal number (with uppercase letters).

Type Handling

Type	Specifiers
String	S
Integer	d, u, c, o, x, X, b
Double	g, G, e, E, f, F

args(optional)- This parameter represents an array with arguments inserted at the third, fourth, etc. %-sign in the format string.

Return

This function returns the array values after formatting the specified string according to the given format or return FALSE on failure.
