PHP gets _php tutorial for getting the nearest number within a specified range

PHP gets the closest number of methods in the specified range, and PHP gets

This example describes the method by which PHP obtains the nearest number within a specified range. Share to everyone for your reference. The implementation method is as follows:

Returns the next higher or lower numberfunction nextrelatednumber ($number, $range) {$r = $number% $range;  $f = $number-$r;  $b = Round ($r/$range, 0); return ($b = = 1)?  $f + $range: $f;  }//Returns the next higher numberfunction nexthighernumber ($number, $range) {$r = $number% $range;  $f = $number-$r;  $b = Ceil ($r/$range); return ($b = = 1)?  $f + $range: $f;  }//Returns the next lower numberfunction Nextlowernumber ($number, $range) {$r = $number% $range;  $f = $number-$r;  $b = Floor ($r/$range); return ($b = = 1)?  $f + $range: $f;  }//Returns the next related number from an arrayfunction Nextnumberarray ($Number, $NumberRangeArray) {$w = 0;  $c =-1;  $abstand = 0;      $l = count ($NumberRangeArray);    for ($pos =0; $pos < $l; $pos + +) {$n = $NumberRangeArray [$pos]; $abstand = ($n < $Number)?    $Number-$n: $n-$Number;      if ($c = =-1) {$c = $abstand;    Continue      } else if ($abstand < $c) {$c = $abstand; $w =$pos; }} return $NumberRangeArray [$w];} examples//--------//0 ... print ' nextrelatednumber: ';p rint nextrelatednumber (44, 10). "\ n";//returns---40//0 ... print ' nexthighernumber: ';p rint nexthighernumber (41, 20). "\ n";//Returns--60//0 5 ... print ' Nextlowernumber: ';p rint nextlowernumber (57, 5). "\ n";//returns--55//Example with Arrayprint ' Nextnumberarray: ';p rint Nextnumberarray (3, 8, 19, 34, 56, 89)). "\ n";//Returns-34//(is between and all but the next)
