== Printing Formatting Strings in PHP ==
Those familar with other programming langusges such as C and C++ will probably be familiar with the concept of formatting strings and the ''printf()'' function. The printf function allows strings to constructed which contain variables and provides a number of formatting options for those variables.
Essentially printf allows you to specify a string and define how particular variables are to be embedded in that string. ''fprintf()'' takes two or more arguments and takes the the following form:
fprintf ( "String containing embedded formatting rules", variable1, variable2, ..., +/-, 'padding char', +/-, width, precision, type );
PHP will scan the string for the formatting specifiers or rules and substitute that rule for the corresponding variable.
