Visual FoxPro/PHP Functions In Lianja

Lianja has a complete cross-platform Visual FoxPro scripting language implementation built-in. The Visual FoxPro implementation has many functions and language extensions not available in Visual FoxPro 9. For example, The following PHP functions (which will be familiar to PHP developers) are built-in and can be used by Visual FoxPro developers. Some of these functions are available by a different name in Visual FoxPro but are included to make it easier for PHP developers to develop in Lianja Scripting which unlike PHP is a data-centric scripting language.

Note that you can write your code directly in PHP if that's what you want to do as Lianja is scripting language independent and fully supports Visual FoxPro, Python, PHP and JavaScript

Special notes

The format for printf(), sprintf() and fprintf() can contain any of the following formatting characters.

%s %d %f %y %t %T %l %L. Each formatting character sequence can optionally contain a width and decimal places (only relevant for numeric). Left justify by placing a '-' directly following the '%' character e.g. %-20s or %-14.2f. When %s is specified, the corresponding argument is converted to character format (similar to specifying etos(). %t and %T are for formating datetime data types. %y is for formatting currency data types %l and %L is for formatting logical datatypes

The format for the strftime() function can contain any of the following formatting characters.

%a - abbreviated weekday name%A - full weekday name%b - abbreviated month name%B - full month name%c - preferred date and time representation%C - century number (the year divided by 100, range 00 to 99)%d - day of the month (01 to 31)%D - same as %m/%d/%y%e - day of the month (1 to 31)%g - like %G, but without the century%G - 4-digit year corresponding to the ISO week number (see %V)%h - same as %b%H - hour, using a 24-hour clock (00 to 23)%I - hour, using a 12-hour clock (01 to 12)%j - day of the year (001 to 366)%m - month (01 to 12)%M - minute%n - newline character%p - either am or pm according to the given time value%r - time in a.m. and p.m. notation%R - time in 24 hour notation%S - second%t - tab character%T - current time, equal to %H:%M:%S%u - weekday as a number (1 to 7), Monday=1.
