This article mainly introduces the example codes for PHP calculation of two particularly large integers. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

No more nonsense. , the specific code is as follows:

function getIntAdd($a,$b){ $c = ''; $bCount = strlen($b); $aCount = strlen($a); $count = max($bCount,$aCount); $aDiff = $count - $aCount; $bDiff = $count - $bCount; for($i = $count - 1;$i >= 0;$i--){ $aVal = $count - $i <= $aCount ? intval($a[$i - $aDiff]) : 0; $bVal = $count - $i <= $bCount ? intval($b[$i - $bDiff]) : 0; $v = $aVal + $bVal; if(strlen($c) > 0 && strlen($c) >= $count - $i){ $c = ($v + intval($c[0])).substr($c,1,strlen($c) - 1); }else{ $c = $v.$c.''; } } return $c; } $a = '23490234328490289048902384908392849238'; $b = '234320498324982390489328498230984982399290384902384'; $c = getIntAdd($a,$b); print_r($c);
