我有这个 php 代码:
<?php
$numarray = trim($_GET['num']);
$i = strlen($numarray);
$result = "";
$numneedarray = array(
90 => 'ninety',
80 => 'eighty',

20 => 'twenty',
19 => 'nineteen',
18 => 'eighteen',
17 => 'seventeen',
16 => 'sixteen',
15 => 'fifteen',
14 => 'fourteen',
13 => 'thirteen',
12 => 'twelve',
11 => 'eleven',
10 => 'ten',
9 => 'nine',
8 => 'eight',
7 => 'seven',
6 => 'six',
5 => 'five',
4 => 'four',
3 => 'three',

for ($v = 1; $v <= $i; $v++) {

exit("Has to be 10-digit or less.");

$result .= ", " . $numneedarray[$numarray[strlen($numarray) - 3]] . " hundred";
if ($numarray % 100 == 0) {
echo "Hi95";
break;
}
} elseif ($i == 2) {
if ($numarray[$v] == 1) {
$othernum = $numarray[strlen($numarray) - 1];
$othernum2 = $numarray[strlen($numarray) - 2] * 10;
$othernum3 = $othernum2 + $othernum;
if (strlen($numarray) > 2) {
$result .= " and ";
}
$result .= $numneedarray[$othernum3];
echo "Hi107";
} else {
$othernum = $numarray[strlen($numarray) - 2] * 10;

$result .= " and " . $numneedarray[$othernum] . " " . $numneedarray[$othernum2];

}
}
echo $i;

}
if (strlen($numarray) == 1) {
echo $numneedarray[$numarray];
}
echo $result;
?>
该num
值等于1234567890
。当我刷新页面时, 的值$i
只会从10 -> 9 -> 8 -> 7 -> 6
然后突然停止。为什么循环会停止运行?
