php - HTML Dom Parse 5000 + Items -


is there anyways run/write code below efficiently?

when run (via chrome browser) tends time-out around 500th item , redirect me homepage.

<?php  include_once('config.php'); include_once('simple_html_dom.php');  for($i = 0; $i <= 5000; ++$i){  // retrieve dom given url $html = file_get_html($url);  // loop checks through page contents , retrieves required foreach($html->find('div.product-details-contents') $content) { $detail['productid'] = $i; $detail['title'] = $content->find('span.title', 0)->plaintext; $detail['unit'] = $content->find('span.unit-size', 0)->plaintext;  $sqlstring = implode("','", $detail);   $sql = "insert `cdidlist` (`productid`, `title`, `unit`) values ('$sqlstring')";  if (!mysqli_query($connect, $sql)) { echo "error: " . mysqli_error(); } echo $id . " " . $detail['title'] . " item added sucsessfully! <br>";      } } ?>

you opening 5000 webpages , parsing them. can't done efficiently. keep script die'ing, can use set_time_limit(600) inside of loop, making sure have appropriately high timeout in php.ini well.

edit: don't own server. means going have push off client side. go this:

php: 

if(isset($_request['i'])) {    $i = (int) $_request['i']; // sanitize input    $error_message = false;    /*      load page, parse page , input db.      if there error, save $error_message    */    if(!$error_message) {        die(json_encode('ok')); // die'ing bad, one-off script    } else {        die(json_encode($error_message));    } }

in html:

<p id="status">status</p> <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script type="text/javascript">   $(function () {      'use strict';      var = function (i) {          if (i > 5000) {              $('#status).html('complete');          } else {             $.get({                 url: window.location.href,                 data: {i: i},                 success: function (data) {                    if(data === 'ok'){                       $('#status').html('fetched ' + i);                       get(i + 1);                    } else {                       $('#status').html('error fetching ' + + ': ' + data);                    }                 }               });          }      };      get(0);   }); </script>

edit 2: others have mentioned, vulnerable sql injection. please see pdo , pdostatement prepared statements.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
