我有这个问题:这个脚本检查链接上某个列表的 pagerank。当我插入〜150个链接时,它可以正常工作,但是如果我放置大量链接,则会显示以下错误:
这是代码:
<?php

for ($i = 0; $i < $length; $i++) {
$Check *= $Magic;
if ($Check >= $Int32Unit) {
$Check = ($Check - $Int32Unit * (int) ($Check / $Int32Unit));
$Check = ($Check < -2147483648) ? ($Check + $Int32Unit) : $Check;
}
$Check += ord($Str{$i});
}
return $Check;
}

{
$CheckByte = 0;

$HashStr = sprintf('%u', $Hashnum) ;
$length = strlen($HashStr);

if (1 === ($Flag % 2) ) {

}
$CheckByte >>= 1;
}
}
return '7'.$CheckByte.$HashStr;
}
function HashURL($String)
{
$Check1 = StrToNum($String, 0x1505, 0x21);
$Check2 = StrToNum($String, 0, 0x1003F);
$Check1 >>= 2;
$Check1 = (($Check1 >> 4) & 0x3FFFFC0 ) | ($Check1 & 0x3F);
$Check1 = (($Check1 >> 4) & 0x3FFC00 ) | ($Check1 & 0x3FF);
