PHP vsprintf() Function

The vsprintf() function writes a formatted string to a variable.

Unlike sprintf(), the arguments in vsprintf(), are placed in an array. The array elements will be inserted at the percent (%) signs in the main string. This function works "step-by-step". At the first % sign, the first array element is inserted, at the second % sign, the second array element is inserted, etc.

If there are more % signs than arguments, you must use placeholders. A placeholder is inserted after the % sign, and consists of the argument- number and "\$". See example two.

string vsprintf ( string $format , array $args )

Operates as sprintf() but accepts an array of arguments, rather than a variable number of arguments.

Example -

Example #1 vsprintf(): zero-padded integers

ParameterDescription
