Validating date in php

* @param type $format The format the date should be in.

Christos Pontikis has done a great post on the best way to use the class and how to work around it’s current limitations. It basically involves explicitly checking the Date Time::get Last Errors() function to see if the date was valid or not.

$date ) return FALSE; // $date is trimed $date = trim( $date ); // If $format empty return to default, else UPPERCASE and trim. 'YYYY-MM-DD' : strtoupper( $format ); // $format is 10 char in length and contains all the required chars if( strlen( $format ) !

More times than I can count I’ve had to validate dates in PHP, not only check if it is in the required format but also to make sure the date actually exists.Until recently there has not been a good, native way of doing this, yes checkdate() has been around for a while but it’s particularly fussy with it’s input, what we needed was a mixture of date() where we can specify the input format and checkdate() to validate it. Technically available from PHP =5.3.0 due to bugs and missing features, (Date Time::create From Format or Date Time::get Last Errors in particular).Among it’s many cool new features the best is Date Time::create From Format() which allows you to re-format an inputted date.Yes it’s very similar to using date() & strtotime() together BUT this has all sorts of useful additions, the most important of which is error checking.filter_var( ( int ) $date_parts[ $i ], FILTER_VALIDATE_INT ) ) return FALSE; // Compare $date_part length to equivilent $format_part length if( strlen( $date_parts[ $i ] ) !

= strlen( $format_parts[ $i ] ) ) return FALSE; // Set our variables so we check it's a valid date later if( $format_parts[ $i ][0] == 'Y' ){ $year = $date_parts[ $i ]; } elseif( $format_parts[ $i ][0] == 'M' ){ $month = $date_parts[ $i ]; } elseif( $format_parts[ $i ][0] == 'D' ){ $day = $date_parts[ $i ]; } } // Finally, check it's a valid date if( checkdate( $month, $day, $year ) ){ return TRUE; } else { return FALSE; } } If you know you’re going to be using a more modern version of PHP you can take advantage of the very cool and now native Date Time class.
