我正在尝试建立一个网站，您在一页（下方）中输入了非校验位IMEI列表

然后提交到此页面

//seperate numbers that become double digits
if ($D[$i] > 4) {
//convert int to string
$sumS = (string)$sum;
//clear array
unset($splitt);
//seperate the numbers and add them together
for ($j = 0; $j <= 1; $j++) {
$splitt[]=$sumS[$j];
$sumeven = $sumeven + $splitt[$j];
}
//else just add the single number to the last

}
}
// adding odd numbers together
$sumodd = 0;
$sum = 0;
for ($i = 0; $i <= 13; $i=$i+2) {

}
// add odd and even numbers

//convert int to string

//Split total into two variables

}
if ($split[1] == 0) {
$zero = 0;
$IMEIZERO = $imei.$zero;
//print $IMEIZERO;
} else {

$totalNew = $split[0]."0";
$chk = $totalNew - $total;

然而，我很难想到如何让它不止一次打印或回显，并将唯一值打印/回显到textarea中，例如，如果我想得到以下14位数字的校验位IMEI＆＃39 ; S 15832859381748 18247395837243 52835621351219 12583582923852
我想把它们放到第一页，按提交并将它们放在第二页上，末尾带有校验位。所以喜欢这个
158328593817484 182473958372434 528356213512196 125835829238525
有什么想法吗？
非常感谢
答案 0 :(得分：0)
让用户每行输入一个数字，然后在收到时使用PHP的explode()功能。你最终得到了所有IMEI的数组。
我无法抗拒修正校验和计算的冲动，有内容的注释来解释一些函数的作用。
$imeis = explode("\n", $_POST['IMEI']);
$output = "";
foreach ($imeis as $imei) {
$sum = 0;
//str_split converts strings to arrays
//array_reverse reverses arrays; that is how the checksum should be done
$imeiRev = array_reverse(str_split(trim($imei)));
//loop through each digit in the now-reversed IMEI
foreach ($imeiRev as $i=>$digit) {
if ($i % 2 === 0 && $digit > 4) {
//it's even and greater than 4
$digit = array_sum(str_split($digit * 2));
} elseif ($i % 2 === 0) {
//it's even
$digit = $digit * 2;
}
//add to our running total
$sum += $digit;
}
$sum = str_split($sum * 9);
//array_pop just "pops" the last value off
$checkdigit = array_pop($sum);
//add it to the IMEI
$output .= "$imei$checkdigit\n";
}
?>
