note 72958 added to function.date

Check this out this is a class i made last year for Gizzle.co.uk but sinced used on other projects and is quite a treat. It checks for a absolute valid date or datetime type. returns booleen. Disclaimer I do not take responsibility for the use of this class. I guarantees it works. <?php #Created By Eamon Straughn, Class extends Date() informally class isDate { private $arg; private $return = false; private $stack; private $stacks; private $pos = array(); private $poss = array(); public function __construct($arg) { $this->arg = trim($arg); } private function DateType() { //if length is more than 10 then it is not a date if(($n = strlen($this->arg)) > 10) return false; //if length is less than 6 then it is not a date elseif($n < 6) return false; //get values into arrays for processing for($i = 0; $i < $n; $i ++) { if(is_numeric($this->arg[$i])) $this->stack .= (isset($this->arg[$i])) ? $this->arg[$i] : null; elseif(($this->arg[$i] == "-") || ($this->arg[$i] == "/") || ($this->arg[$i] == "\\")) $this->pos[$i] = (isset($i)) ? $i : null; } //strip values to be checked if(is_numeric($c = substr($this->stack, 0, current($this->pos)))) $d = (strlen($c) > 2) ? substr($this->stack, current($this->pos), current($this->pos)/2) : substr($this->stack, current($this->pos), current($this->pos)); else return false; if(is_numeric($d)) if(is_numeric($e = substr($this->stack, end($this->pos)-1, end($this->pos)-1))); //convert string to integer $c = (int) $c; $d = (int) $d; $e = (int) $e; //check if it is a valid date if((checkdate($d,$c,$e)) || (checkdate($d,$e,$c))) return true; return false; } private function DateTimeType() { //if length is more than 10 then it is not a datetime if(($n = strlen($this->arg)) < 10) return false; //if length is less than 19 then it is not a datetime elseif($n < 19) return false; //get values into arrays for processing for($i = 0; $i < $n; $i ++) { if(is_numeric($this->arg[$i])) $this->stacks .= (isset($this->arg[$i])) ? $this->arg[$i] : null; elseif(($this->arg[$i] == "-") || ($this->arg[$i] == "/") || ($this->arg[$i] == "\\") || ($this->arg[$i] == " ") || ($this->arg[$i] == ":")) $this->poss[$i] = (isset($i)) ? $i : null; } //strip values to be checked if(is_numeric($c = substr($this->stacks, 0, current($this->poss)))) $d = (strlen($c) > 2) ? substr($this->stacks, current($this->poss), current($this->poss)/2) : substr($this->stacks, current($this->poss), current($this->poss)); else return false; if(is_numeric($d)) $e = (strlen($c) > 2) ? substr($this->stacks, next($this->poss)-1, (next($this->poss)-1)/4) : substr($this->stacks, next($this->poss)-1, (next($this->poss)-1)/2); if(is_numeric($e)) if(is_numeric($f = substr($this->stacks, (next($this->poss)/2)+2, 2))); if(is_numeric($g = substr($this->stacks, (next($this->poss)/2)+2, 2))); if(is_numeric($h = substr($this->stacks, (end($this->poss)/2)+4, 2))); //convert string to integer $c = (int) $c; $d = (int) $d; $e = (int) $e; $f = (int) $f; $g = (int) $g; $h = (int) $h; //check if the time is valid if($f > 24) return false; if($g > 60) return false; if($h > 60) return false; //check if it is a valid date if((checkdate($d,$c,$e)) || (checkdate($d,$e,$c))) return true; return false; } public function DateCheck() { if($this->DateTimeType()) $this->return = true; elseif($this->DateType()) $this->return = true; else $this->return = false; return $this->return; } } ?> example of use <?php //assign a date $d = "2006-12-12 10:15:00"; $t = "12-12-2006"; $f = "1-1-2001 10:23:09"; //the above can be used regardless if it is shortdate or long date but remember the year must always be 4 integers. $c = new isDate($d); if($c->CheckDate() !== false) echo $d; ?> if anyone wants to extend it to check time and posibly do more feel free to.
