IMEI一次使用PHP检查多个IMEI上的数字
[英]IMEI check digit on more than one IMEI at a time with PHP
问题描述
我正在尝试创建一个网站，您在一个页面上输入一个非校验位IMEI的列表（下面）

<textarea required id="IMEI" rows="16" class="font-fixed-width" style="width: 90%;margin : 0 auto; display: block" name="IMEI"></textarea>
</br>
<p><div id="center"><input type="submit"></div></p>
</form>
</div>
</div>
</body>
</html>
然后它提交到此页面
<?php
$imei = $_POST['IMEI']; //chk has to be 8
//select numbers from imei and add to array
for ($i = 0; $i <= 14; $i++) {
$D[]=$imei;
}
$sumeven = 0;
// adding even numbers together
for ($i = 1; $i <= 14; $i=$i+2) {
$sum = $D[$i]*2;
//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
} else {
$sumeven = $sumeven + $sum;
}
}
// adding odd numbers together
$sumodd = 0;
$sum = 0;
for ($i = 0; $i <= 13; $i=$i+2) {
$sum = $D[$i];
$sumodd = $sumodd + $sum;
}
// add odd and even numbers
$total = $sumodd + $sumeven;
//convert int to string
$totalS = (string)$total;
//Split total into two variables
for ($i = 0; $i <= 1; $i++) {
$split[]=$totalS[$i];
}
if ($split[1] == 0) {
$zero = 0;
$IMEIZERO = $imei.$zero;
//print $IMEIZERO;
} else {
$split[0] = $split[0] + 1;
$totalNew = $split[0]."0";
$chk = $totalNew - $total;
$IMEICHK = $imei.$chk;
//print $IMEICHK;
}
?>
<html>
<head>
</head>
<body>
<textarea id="txtList" rows="16" class="font-fixed-width" style="width: 100%;" name="txtList">
<?php print $IMEICHK OR $IMEIZERO?>
</textarea>
</body>
</html>
但是，我很难想到如何使它打印或回显不止一次并打印/回显唯一值到textarea中，例如，如果我想得到以下14位数的校验位IMEI的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。 就像这样
158328593817484 182473958372434 528356213512196 125835829238525
有任何想法吗？
非常感谢你

让用户每行输入一个数字，然后当你收到它时，使用PHP的explode()函数。 你最终得到了所有IMEI的数组。
我无法抗拒修复校验和计算的冲动，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";
}
?>
