Question

我在$ pages数组变量的给定页面中有下面提到的关键字搜索代码，它按我的意思工作，但由于$ pages数组中有多个页面，因此需要花费很多时间。如何提高这个速度？请告诉我。

<?php 
$match="";
 if(isset($_POST['submit'])){
     if(isset($_POST['txt_search'])){
         $match=trim($_POST['txt_search']);
     }
     if($match==""){
       print "Please enter search text";exit;
     }
 }     
<html>
  <body>    
    <form action="" method="post">
      <input type="text" name="txt_search" placeholder="Search term"/>
      <input type="submit" value="Search" name="submit" onClick=""/>
    </form>
    <p id="text">
       <?php if($match!=""){
          mastersearch($match);
       }?>
    </p>
  </body>
</html>
<?php
 function mastersearch($match) {
    $pages=array("index.php","about.php","contact.php","books.php","careers.php","shopping.php","travels.php","lifestyle.php","movies.php","museum.php");
    foreach ($pages as $value) {
        $text=$value; 
        $path="http://sitename.com/user/";
        $value = $path.$value;
        $json = file_get_contents($value);
        $lastPos=0;
        $last=strripos($json, $match);
        while (($lastPos = stripos($json, $match, $lastPos))!== false) {
            $positions[] = $lastPos;
            preg_match("/<title>(.*)<\/title>/i", $json, $title);
            print $title[1];
            print "<br><a href='$value'>$text</a><br/>";
            $lastPos = $lastPos + strlen($match);
        }
    }
 }
?>

如果你time your script，我认为file_get_contents()电话是昂贵的。这取决于您与远程站点的连接，因此为了加快速度，您可以改善连接或引入某种缓存
