php - 对于功能不起作用

Question

代码应该取10872到10878之间的内容，但它只取10872的内容。

错在哪里？你能帮帮我吗？

<?php
error_reporting(E_ALL ^ E_NOTICE);
set_time_limit(999999);
mysql_select_db("test",mysql_connect("localhost","test","test"));
          @mysql_query("SET NAMES 'LATIN5'");
          @mysql_query("SET CHARACTER SET LATIN5");
          @mysql_query("SET COLLATION_CONNECTION = 'latin5_turkish_ci'");

Function duzenle($text){
$gkod   = array('<FONT size=2 face?"Verdana, Arial, Helvatica, sans-serif">','</FONT>','</DIV>','<DIV>','<DIV>');
$dkod   = array('','','<br />','');
$ykod   = str_replace($gkod,$dkod,$text);
return $ykod;
}

$nereden = "10872";
$nereye = "10878";

for($a=$nereden; $a<=nereye; $a++){
$site = "http://stackoverflow.com/";
$link = "http://stackoverflow.com/questions/$a";
$parcala = '@<div class="post-text" itemprop="text">(.*?)<div class="post-taglist">@si';



$botara = file_get_contents($link);
  preg_match_all($parcala,$botara,$baslik);



$botbaslik = addslashes($baslik[1][0]);

$save = mysql_query("insert into deneme (yazi) values 
('$botbaslik')");

if($save){
  echo"<p style='color :green'> $botbaslik Basariyla eklendi</p>";
  }else{
  echo"<p style='color :red'> $botbaslik Basariyla eklenmedi</p>";
  }
}


?>

你写

   $nereden = "10872";
   $nereye = "10878";

  for($a=$nereden; $a<=nereye; $a++){ // put $a<=$nereye insted of $a<=nereye
   $site = "http://stackoverflow.com/";
     $link = "http://stackoverflow.com/questions/$a";

$variable ($) 在 php 中必须有变量值
