PHP - Best Way To Run 1000+ Querys Per Page

This topic has been moved to MySQL Help.

http://www.phpfreaks.com/forums/index.php?topic=320461.0

need your suggestion here is my problem i have field varchar(1000) in my sql server 2008 DB but if i mssql_fetch_object($result) my field value truncated and only show 256 character, why ?
in my DB . my field value really 1000 character long .

If I want to read in and process a CSV of a 1000 lines how easy is it to do without a database?

By process, I mean read in the data and do simple manipulations + compare each line with a line from another file, that maybe have 50 lines

I was just concerned that I might start hogging the CPU and memory of the server trying to process 1000 lines of data
It's VERY important that I can do WITHOUT a database

I'd only consider a database if it proves that not using will take too much CPU and memory

I've only just began considering making the application - can't give full details - as I've got to figure them out myself!

Any general advice would be great

Thanks

Quesion: Show each movie in the database on its own page, and give the user links in a "page 1, Page 2, Page 3" - type navigation system. Hint: Use LIMIT to control which movie is on which page. I have provided 3 files: 1st: configure DB, 2nd: insert data, 3rd: my code for the question. I would appreciate the help. I am a noob by the way.

First set up everything for DB:

<?php
//connect to MySQL
$db = mysql_connect('localhost', 'root', '000') or
    die ('Unable to connect. Check your connection parameters.');

//create the main database if it doesn't already exist
$query = 'CREATE DATABASE IF NOT EXISTS moviesite';
mysql_query($query, $db) or die(mysql_error($db));

//make sure our recently created database is the active one
mysql_select_db('moviesite', $db) or die(mysql_error($db));

//create the movie table
$query = 'CREATE TABLE movie (
        movie_id        INTEGER UNSIGNED  NOT NULL AUTO_INCREMENT,
        movie_name      VARCHAR(255)      NOT NULL,
        movie_type      TINYINT           NOT NULL DEFAULT 0,
        movie_year      SMALLINT UNSIGNED NOT NULL DEFAULT 0,
        movie_leadactor INTEGER UNSIGNED  NOT NULL DEFAULT 0,
        movie_director  INTEGER UNSIGNED  NOT NULL DEFAULT 0,

        PRIMARY KEY (movie_id),
        KEY movie_type (movie_type, movie_year)
    )
    ENGINE=MyISAM';
mysql_query($query, $db) or die (mysql_error($db));

//create the movietype table
$query = 'CREATE TABLE movietype (
        movietype_id    TINYINT UNSIGNED NOT NULL AUTO_INCREMENT,
        movietype_label VARCHAR(100)     NOT NULL,
        PRIMARY KEY (movietype_id)
    )
    ENGINE=MyISAM';
mysql_query($query, $db) or die(mysql_error($db));

//create the people table
$query = 'CREATE TABLE people (
        people_id         INTEGER UNSIGNED    NOT NULL AUTO_INCREMENT,
        people_fullname   VARCHAR(255)        NOT NULL,
        people_isactor    TINYINT(1) UNSIGNED NOT NULL DEFAULT 0,
        people_isdirector TINYINT(1) UNSIGNED NOT NULL DEFAULT 0,

        PRIMARY KEY (people_id)
    )
    ENGINE=MyISAM';
mysql_query($query, $db) or die(mysql_error($db));

echo 'Movie database successfully created!';
?>

second file to load info into DB:



<?php
// connect to MySQL
$db = mysql_connect('localhost', 'root', '000') or
    die ('Unable to connect. Check your connection parameters.');

//make sure you're using the correct database
mysql_select_db('moviesite', $db) or die(mysql_error($db));

// insert data into the movie table
$query = 'INSERT INTO movie
        (movie_id, movie_name, movie_type, movie_year, movie_leadactor,
        movie_director)
    VALUES
        (1, "Bruce Almighty", 5, 2003, 1, 2),
        (2, "Office Space", 5, 1999, 5, 6),
        (3, "Grand Canyon", 2, 1991, 4, 3)';
mysql_query($query, $db) or die(mysql_error($db));

// insert data into the movietype table
$query = 'INSERT INTO movietype
        (movietype_id, movietype_label)
    VALUES
        (1,"Sci Fi"),
        (2, "Drama"),
        (3, "Adventure"),
        (4, "War"),
        (5, "Comedy"),
        (6, "Horror"),
        (7, "Action"),
        (8, "Kids")';
mysql_query($query, $db) or die(mysql_error($db));

// insert data into the people table
$query  = 'INSERT INTO people
        (people_id, people_fullname, people_isactor, people_isdirector)
    VALUES
        (1, "Jim Carrey", 1, 0),
        (2, "Tom Shadyac", 0, 1),
        (3, "Lawrence Kasdan", 0, 1),
        (4, "Kevin Kline", 1, 0),
        (5, "Ron Livingston", 1, 0),
        (6, "Mike Judge", 0, 1)';
mysql_query($query, $db) or die(mysql_error($db));

echo 'Data inserted successfully!';

MY CODE FOR THE QUESTION:


<?php
$db = mysql_connect('localhost', 'root', '000') or
die ('Unable to connect. Check your connection parameters.');

mysql_select_db('moviesite', $db) or die(mysql_error($db));

//get our starting point for the query from the URL
if (isset($_GET['offset'])) {
   $offset = $_GET['offset'];
} else {
   $offset = 0;
}

//get the movie
$query  = 'SELECT
   movie_name, movie_year
FROM
   movie
ORDER BY
   movie_name
LIMIT ' . $offset . ' , 1';
$result = mysql_query($query, $db) or die(mysql_error($db));
$row = mysql_fetch_assoc($result);
?>
<html>
<head>
<title><?php echo $row['movie_name']; ?></title>
</head>
<body>
<table border = "1">
<tr>
<th>Movie Name</th>
<th>Year</th>
</tr><tr>
<td><?php echo $row['movie_name']; ?></td>
<td><?php echo $row['movie_year']; ?></td>
</tr>
</table>
<p>
<a href="page.php?offset=0">Page 1</a>,
<a href="page.php?offset=1">Page 2</a>,
<a href="page.php?offset=2">Page 3</a>
</p>
</body>
</html>

Some code from my pages ,   Page1 ( Redirecting page )

<html>
<title>login_redirect.</title>
body>

<form name="redirect" action="http://mysite/page2.php" method="post">
<input type="hidden" name="mac" value="$(mac)">
</form>

<script language="JavaScript">
<!--
document.redirect.submit();
//-->
</script>
</body>
</html>

Page 2 ( select product )

<?php


session_start();

ini_set('display_errors',1);
error_reporting(E_ALL); 

include '../lib/config.php';
include '../lib/opendb.php';

// get user mac adres from redirect post page1
$_SESSION['macid'] = $_POST['mac'];
// set $macid for other use ( maybe not needed, am learning )
$macid = $_SESSION['macid'];

// echo $macid does show mac adress, so variable is not empty here


if (!empty($_POST["submit"]))

{
$product_choice = $_POST['accounttype'];
$query= "SELECT AccountIndex, AccountCost, AccountName FROM AccountTypes WHERE AccountIndex='$product_choice'";
$result = mysql_query($query) or die('Query failed. ' . mysql_error()); 
while($row = mysql_fetch_array($result))
{
$_SESSION['AccountIndex'] = $row['AccountIndex'];
$_SESSION['AccountCost'] = $row['AccountCost'];
$_SESSION['AccountName'] = $row['AccountName'];
}


header('Location: page3.php');

}

// did leave out the other/html/form stuff here

Page 3 ( show Session variables )

<?php


ini_set('display_errors',1);
error_reporting(E_ALL); 

session_start();

print_r($_SESSION);

?>

Now, on page 3 i do see the right session varables, only the "macid" is empty.   why ?

I am using Magento (Ver 1.9.x)

If i try with my localhost success url like,

http://192.168.1.65/magento/index.php/checkout/onepage/success/ and return success message with order id.

if i try with live, success url like,

https://abc.in/payubiz/redirect/success/ success page like blank page.

How to solve the issue?

Code : https://github.com/ZusZus/Payubiz

Edited February 4, 2020 by aveeva

I have a page with results from a query that displays that has a link (works fine - passes variables etc) that deletes that line item from a database.  It goes to the delete.php and actually executes and removes the item from the database and then has the line header("Location: page.php"); which returns BACK to the page displaying the results.  However, it shows the old results until I hit Refresh in the browser.  Its like the header is redirecting to a cached version of the page.     NOTE:  This script used to work fine untouched when we where on a shared hosting account.  We JUST updates to VPS hosting by the same host.  Now this problem has risen and I can't figure out what is wrong.  From what I can guess is there is something in php.ini that is either not set, set or set wrong.  Any help would be greatly appreciated.   Thanks.

Can someoneplease help, I need to setup an error page like IF Username and Password are wrong then show an error also if there is no username or password in the fields and I just click LOGIN, I get a blank page?!

Can someone please help me here or point me to a relevant tutorial?

thanks

here is my page:
http://www.retroandvintage.co.uk/default.php

here is my  code:

<?php
session_start();
include_once("config.php");

$ebits = ini_get('error_reporting');
error_reporting($ebits ^ E_NOTICE);
/*
Login script:
This script does the following:

Checks that the user is NOT already logged in - if they are they
are redirected to the members page by the 'checkLoggedIn()' function.

Checks if the login form has been submitted - if so, the 'login' and
'password' fields are checked to ensure they are of the correct format and length.
If there are any problems here an error is added to the $messages array and
then the script executes the 'doIndex()' function - this function basically
outputs the main 'index' page for this script - ie the login form.

If there are no problems with the previous step, the 'login' and 'password'
field data is passed to the 'checkPass' function to check that an entry
exists in the 'users' table for that login/password pair.
If nothing is returned from the 'checkPass()' function, an error is
added to the $messages array and the 'doIndex()' function is called as above.

If a row of data is returned from the 'users' table, the data is passed to
the 'cleanMemberSession()' function - which initializes session variables and
logs the user in.  The user is then forwarded to the members page.

If the form hasn't yet been submitted, then the 'doIndex()' function is called
and the login page is displayed.

Hi,

Is it possible to build a PHP Template page that selects and publishes a row of data from a MySQL Database when a linked is clicked?

I would design: Template.php
Text links (perhaps on homepage of navigation bar): ProductA, ProductB and ProductC

If you click link ProductA Template.php would display data for ProductA and likewise for ProductB and ProductC.

I would also like search engines for find ProductA, ProductB and ProductC PHP pages. (Not just my single Template.php)

Any ideas as to how this could be done without designing individual PHP pages for each product?

Kind regards,

Matthew.

Hi,

I am a php newbie, who has a page that relies on some php scripts, and to which I am trying to add a login page written in php.  I took the example from he

http://www.howtodothings.com/computers-internet/how-to-make-a-login-system-for-your-website

Basically it consists of adding:

<?
require("log.php");
?>

to the top of any page I want to protect, a log.php file which performs the actions of the form, linking to a mySQL database, and a login.php file which contains the form.

I have the login working fine, but it breaks one of the PHP scripts on the page that is protected.  It is an upload script, called Weaverbox, based on FancyUpload.  The uploads which are handled by a file called upload.php, aren't happening.  The progress shows that they are being uploaded, but nothing is uploaded, and there is no success message.  As soon as I remove the code from the top of the page requiring log.php all works fine again.

I think I may have to add some rules/extensions to resolve this conflict, but I don't know how to go about this.  Would someone be able to help me get it sorted?

Thanks

Nick

i am creating a responsive website.    I'll give you an example.   I am retriving 100 items from mysql database using php.  I am only showing 20 items per page using simple pagination with arrows.  I keep this format on desktop and tablets.  However, I would like to show less items when I am viewing the page on a smartphone.  So instead of 20 items per page, it'll show 5 items per page along with the pagination arrows.    I was wondering if this is possible with PHP or would I have to use javascript?

ONE of my SESSION values isn't remaining after login while others do.

This works fine on my localhost, it's on the live site that there is a problem and it just started yesterday. Before that it worked great.

Out of the four SESSIONs made I can only echo three values on other pages, member id the most important doesn't transfered to other pages

Notes: all these files are in the same folder, there is a SESSION started for the member id on the login page, you can see that it is used in the redirect below and the redirect works fine with the redirect going to the correct page " $home/member/index.php?user=$id_mem "

Here is the login page
// Here's the basic login page info
<?php # login.php
session_start();
ob_start() 
...connect to db & header called...
...Form validation.....

if ($e && $p) { // If everything's OK.
// Query the database:
$q = "SELECT id_mem, display_name, mem_group FROM sn_members WHERE (email='$e' AND password=SHA1('$p')) AND active IS NULL";
$r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc));
//  or die("Error: ".mysqli_error($dbc));

if (@mysqli_num_rows($r) == 1) { // If a match was made.

// Register the values & redirect:
// Give SELECTED elements a session
$_SESSION = mysqli_fetch_array ($r, MYSQLI_ASSOC);
$_SESSION['agent'] = md5($_SERVER['HTTP_USER_AGENT']);
mysqli_free_result($r);

// Update db for last login
$id_mem = $_SESSION['id_mem']; // <<< SESSION member id has a value here because it's used in the redirect below
$ip = $_SERVER['REMOTE_ADDR']; // Get ip address of person logging in
$q = "UPDATE sn_members SET last_login = Now(), ip = '$ip' WHERE id_mem = '$id_mem' LIMIT 1";
$r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc));

header("Location: $home/member/index.php?user=$id_mem");
exit(); // Quit the script.

}
?>


Here is the main page that a user would be redirect to above
<?php // /member/ all member info is through this folder
session_start();
ob_start();

if (isset($_GET['user']) && is_numeric($_GET['user'])) {
$user = $_GET['user'];
$user = $user;
if ($user < 0) {
header("Location: $home/index.php");
exit();
}
}

if ((!isset($_SESSION['id_mem']))  && (!isset($_SESSION['agent']) OR ($_SESSION['agent'] != md5($_SERVER['HTTP_USER_AGENT'])))){
// If not a logged in member redirect
header("Location: $home/index.php");
exit(); // Quit the script.
}
?>

Thanks in advance for the help

About a year ago I wrote a mod_rewrite in at sites htaccess file.  It was to call a page that queried the database based on a unite code that was assigned to a member.  If the member was assigned a code that was FL1001, the URL www.marketingteammates.com/FL1001 would bring up a page that quaried that member and displayed their database content.   In the users table of the site, it quaried the field webPageID and the information was called.  It called a page webpage.php that quaried the info.  The URL in the address bar still displayed www.marketingteammates.com/FL1001.  Here are the lines of code in the htaccess file.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([A-Za-z])([A-Za-z])([0-9]+)$ /webpage.php?webPageID=$1$2$3 [NC,L]

I now have a second page completely different from the webpage.php.  It is a page storeNumber.php and would query a field storeNumberID.  This field could contain any kind of string such as Store#101, or mystore101, or #101 is my store.   I tried using the same rewite rule just replaceing the webpage.php and variable with storeNumber.php and $storeNumberID.   This doesn't work.  It also leads me to wonder if there can even be two different pages in the mod_rewrite.  How would it diferentiate one from the other.   Thanks for any help in advance.   Mike
