废话不多说了，具体代码如下所示：
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);
