vsprintf
(PHP 4 >= 4.1.0, PHP 5, PHP 7)
vsprintf — Return a formatted string
Description
$format
, array $args
) : stringOperates as sprintf() but accepts an array of arguments, rather than a variable number of arguments.
Parameters
-
format
-
The format string is composed of zero or more directives: ordinary characters (excluding %) that are copied directly to the result and conversion specifications, each of which results in fetching its own parameter.
A conversion specification follows this prototype: %[flags][width][.precision]specifier.
Flags Flag Description - Left-justify within the given field width; Right justification is the default + Prefix positive numbers with a plus sign +; Default only negative are prefixed with a negative sign. (space) Pads the result with spaces. This is the default. 0 Only left-pads numbers with zeros. With s specifiers this can also right-pad with zeros. '(char) Pads the result with the character (char). Width
An integer that says how many characters (minimum) this conversion should result in.
Precision
A period . followed by an integer who's meaning depends on the specifier:
- For e, E, f and F specifiers: this is the number of digits to be printed after the decimal point (by default, this is 6).
- For g and G specifiers: this is the maximum number of significant digits to be printed.
- For s specifier: it acts as a cutoff point, setting a maximum character limit to the string.
Note: If the period is specified without an explicit value for precision, 0 is assumed.
Note: Attempting to use a position specifier greater than
PHP_INT_MAX
will generate warnings.Specifiers Specifier Description % A literal percent character. No argument is required. b The argument is treated as an integer and presented as a binary number. c The argument is treated as an integer and presented as the character with that ASCII. d The argument is treated as an integer and presented as a (signed) decimal number. e The argument is treated as scientific notation (e.g. 1.2e+2). The precision specifier stands for the number of digits after the decimal point since PHP 5.2.1. In earlier versions, it was taken as number of significant digits (one less). E Like the e specifier but uses uppercase letter (e.g. 1.2E+2). 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). Available as of PHP 5.0.3. g General format.
Let P equal the precision if nonzero, 6 if the precision is omitted, or 1 if the precision is zero. Then, if a conversion with style E would have an exponent of X:
If P > X ≥ −4, the conversion is with style f and precision P − (X + 1). Otherwise, the conversion is with style e and precision P − 1.
G Like the g specifier but uses E and F. o The argument is treated as an integer and presented as an octal number. s The argument is treated and presented as a string. u 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). WarningThe c type specifier ignores padding and width
WarningAttempting to use a combination of the string and width specifiers with character sets that require more than one byte per character may result in unexpected results
Variables will be co-erced to a suitable type for the specifier:

Examples
Example #1 vsprintf(): zero-padded integers
<?php
print vsprintf("%04d-%02d-%02d", explode('-', '1988-8-1'));
?>
The above example will output:
1988-08-01
