The vsprintf() function in PHP is an inbuilt function and used to display array values as a formatted string. The array elements will be inserted at the percent (%) signs in the main string. Display array values as a formatted string according to its format and accepts an array argument in place of variable number of arguments. The function returns formatted string. while vprintf() outputs a formatted string
Syntax:
vsprintf (format, arr_arguments)
Parameters Used : This Function takes Two parameter which are described below-
- format: It has Required parameter. It Specifies how string formatted to be variables. Possible format values as below:
- %% – Returns a percent sign
- %b – Binary number
- %d – Signed decimal number (negative, zero or positive)
- %u – Unsigned decimal number (equal to or greater than zero)
- %x – Hexadecimal number (lowercase letters)
- %X – Hexadecimal number (uppercase letters)
- %f – Floating-point number (local settings aware)
- %F – Floating-point number (not local settings aware)
- %o – Octal number
- %c – The character according to the ASCII value
- %s – String
- %e – Scientific notation using a lowercase (e.g. 1.2e+2)
- %g – shorter of %e and %f
- %G – shorter of %E and %f
- %E – Scientific notation using a uppercase (e.g. 1.2E+2)
- arr_arguments: An array arguments inserted at the % signs formatted string.
Additional format:
- – -> Left-justifies for variable value .
- [0-9] -> maximum string length for number.
- [0-9] -> minimum string width for variable value.
- + -> Used for both[+ or-] (By default its negative number).
Program 1: String space specified program.
php
<?php $str1 = "Geeks"; $str2 = "Geeksforneveropenarticle"; // print string-1 only echo vsprintf("%s\n", array( $str1)); // print string-15 space echo vsprintf("%15s\n", array( $str1)); // print string-1 with space echo vsprintf("%-25s\n", array( $str1)); // print string with zero echo vsprintf("%020s\n", array( $str1)); // print string with * symbol echo vsprintf("%'*10s\n", array( $str1)); // print string-2 echo vsprintf("%s\n", array( $str2)); // print string-2 with decimal point echo vsprintf("%2.10s\n", array( $str2)); // print string-2 with space echo vsprintf("%30s\n", array( $str2)); // print string-2 with zero echo vsprintf("%030s", array( $str2)); ?> |
Output:

Program 2: Drive floating program %f and %F in vsprintf() function in PHP.
php
<?php // %f and %F floating number in // vsprintf function in php $value1 = 789495321; $value2 = 8080907021; $value3 = 334422190; echo "\n%f (local) Floating: "; // for %f Floating-point number // for local settings aware $txt = vsprintf("%f %f %f", array( $value1, $value2, $value3)); echo $txt; echo "\n%F (Not local) Floating: "; // for %F Floating-point number // for local settings aware $result = vsprintf("%F %F %F ", array( $value1, $value2, $value3)); echo $result; ?> |
Output:
%f (local) Floating: 789495321.000000 8080907021.000000 334422190.000000 %F (Not local) Floating: 789495321.000000 8080907021.000000 334422190.000000
Program 3: Implement %d, %u, %e and %E in vsprintf() function.
php
<?php // vsprintf function in php // used %d, %u, %e, %E $value1 = 7894; $value2 = 9070; $value3 = 3344; echo "%d Signed decimal number : "; // %d Signed decimal number // where (-, + or zero) $txt = vsprintf("%d %d %d", array( $value1, $value2, $value3)); echo $txt; echo "\n%u UnSigned decimal number : "; // %d UnSigned decimal number // where (0<=zero) $tt = vsprintf("%u %u %u", array( $value1, $value2, $value3)); echo $tt; echo "\n%e Scientific notation : "; // Scientific notation for lowercase $result = vsprintf("%e %e %e ", array( $value1, $value2, $value3)); echo $result; echo "\n%E Scientific notation : "; // Scientific notation for uppercase $result = vsprintf("%E %E %E ", array( $value1, $value2, $value3)); echo $result; ?> |
Output:
%d Signed decimal number : 7894 9070 3344 %u UnSigned decimal number : 7894 9070 3344 %e Scientific notation : 7.894000e+3 9.070000e+3 3.344000e+3 %E Scientific notation : 7.894000E+3 9.070000E+3 3.344000E+3
Program 4: Implement %%, %b, %o, %x, and %Xin vsprintf() function in PHP.
php
<?php // vsprintf function in php // used %%, %b, %o, %x, %X $value1 = 789495; $value2 = 334455; // Returns [%] sign echo "% ->Returns [%] sign: "; $txt = vsprintf("%% %%", array( $value1, $value2)); echo $txt; // Returns [%b] binary number echo "\n%b ->binary number : "; $tt = vsprintf("%b %b", array( $value1, $value2)); echo $tt; // Returns [%o] octal number echo "\n%o ->octal number : "; $result = vsprintf("%o %o ", array( $value1, $value2)); echo $result; // Returns [%x] Hexadecimal number[lowercase] echo "\n%x ->Hexadecimal number Lc : "; $result = vsprintf("%x %x", array( $value1, $value2)); echo $result; // Returns [%X] Hexadecimal number[Uppercase] echo "\n%X ->Hexadecimal number Uc : "; $result = vsprintf("%X %X", array( $value1, $value2)); echo $result; ?> |
Output:
% ->Returns [%] sign: % % %b ->binary number : 11000000101111110111 1010001101001110111 %o ->octal number : 3005767 1215167 %x ->Hexadecimal number Lc : c0bf7 51a77 %X ->Hexadecimal number Uc : C0BF7 51A77
Program 5:Implement %g %G and %c(ASCII) vsprintf() function in PHP.
php
<?php // vsprintf function in php $value1 = 75; $value2 = 55; $char = 97; $char2 = 69; // shorter of %e and %f echo "%g shorter of %e and %f: "; $txt = vsprintf("%g %g", array( $value1, $value2)); echo $txt; // %G – shorter of %E and %f echo "\n%G shorter of %E and %f : "; $tt = vsprintf("%G %G", array( $value1, $value2)); echo $tt; // ASCII value echo "\n%c ASCII value : "; $result = vsprintf("%c %c ", array( $char, $char2)); echo $result; ?> |
Output:
%g shorter of %e and %f: 75 55 %G shorter of %E and %f : 75 55 %c ASCII value : a E
