PHP - Swap Value Of ->fetch(pdo::fetch_assoc) In While Loop

good day dear community,

i am workin on a Curl loop to fetch multiple pages:

i have some examples - and a question:

Example: If we want to get information from 3 sites with CURL we can do it like so:


$list[1] = "http://www.example1.com";
$list[2] = "ftp://example.com";
$list[3] = "http://www.example2.com";


After creating the list of links we should initialize the cURL multi handle and adding the cURL handles.


$curlHandle = curl_multi_init();
for ($i = 1;$i <= 3; $i++)
 $curl[$i] = addHandle($curlHandle,$list[$i]);


Now we should execute the cURL multi handle retrive the
content from the sub handles that we added to the cURL multi handle.

ExecHandle($curlHandle);
for ($i = 1;$i <= 3; $i++)
{
 $text[$i] =  curl_multi_getcontent ($curl[$i]);
 echo $text[$i];
}

In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle!

If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it!
Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages:
see the some details for this target-server sites - /(I have to create a loop over several hundred sites).

    * siteone.example/?show_subsite=9009
    * siteone.example/?show_subsite=9742
    * siteone.example/?show_subsite=9871

.... and so on and so forth Question: How to appy this loop into the array of the curl-multi?

I look forward to your ideas.

Hi all,

 

I have a query that return data into the array $row with values, but $id from the first line of the while stay null. Why?

$con = oci_connect("xxx", "xxx", "xxx");
$query = "SELECT id, name from table_web WHERE record_module='AA' and parent_id='".$parentId."'";
$stid=oci_parse($con, $query);
oci_execute($stid);
while($value = oci_fetch_assoc($stid))
{
	$id = $value['id'];
    $row[$id]['id'] = $value['id'];
    $row[$id]['name'] = $value['name'];
}
return $row;

 

The following snippit should retrieve 10 images stored in an SQLite database table. But for some reason that mystifies me, it only retrieves 9. (Or one less than the number of images that are actually stored on the table): ___________ # retrieve photos for this property
        
        $query = "SELECT * FROM binary_data where propID = $prop_id";
        $result = $db->query($query);
        $row = $result->fetch(PDO::FETCH_ASSOC);
        
        
        
        # save each image data to file
        foreach($result as $row) {
        $filename = $row['filename'];
        $image = $row['bin_data'];
        file_put_contents($filename, $image);
        }
        ?> _____________ It saves the ones it gets to the temporary files as it should, and they appear on the webpage as they should. But one is always missing. Any suggestions/corrections appreciated. -Robert    

I've been starting to play around the mysqli class and I've been having trouble using it due to various error it gives me from simple queries like this one. I'm not sure what the error is really, I've been following the php manual. Any help would be greatly appreciated.



Code: [Select]
<?php 


$mysqli = new MySQLi('localhost', 'root', 'root', 'jaipai');

if ($mysqli->connect_errno)
{
echo "There was a connection error: ". $mysqli->connecterrno;
}



class testClass 

{

private $db;


function __construct($mysqli)
{
$this->db = $mysqli;
}

public function pageInfo()
{
$query = "SELECT * FROM users WHERE username = jaipai";
$results = $this->db->query($query);

$result = $this->db->fetch_assoc($results);

return $result['username'];

}

}

$testClass = new testClass($mysqli);

echo $testClass->pageInfo();


?>
This gives me this error:
Code: [Select]
Fatal error: Call to undefined method mysqli::fetch_assoc() in /Users/JPFoster/Sites/Research & Development/Programs/Object Sandbox/DatabaseConnection.php on line 30



Just to be a little more informative I've also tried this method
Code: [Select]
$results = $this->db->query($query);

$result = $results->fetch_assoc();

return $result['username'];

This gives me an error:
Code: [Select]
Fatal error: Call to a member function fetch_assoc() on a non-object in Sites/Research & Development/Programs/Object Sandbox/DatabaseConnection.php on line 30

I'm not sure which is on the best path to go. Any help would be greatly appreciated.

Hi everyone, Happy New Year in advance! I have the following error occurring :-

PHP Fatal error: Uncaught Error: Call to a member function fetch_assoc() on bool in /home/website/public_html/include/database.php:31

Line 31 :-

while ($row = $query_result->fetch_assoc()) { $result[] = $row; }

Which is in this query :-

public function DbGetAll($queryString) {
			$query_result = $this->db->query($queryString);
			$result = array();
			while ($row = $query_result->fetch_assoc()) { $result[] = $row; }
			return $result;
		}

 

I'm guessing it's a problem with the sql query but I'm not sure how to fix? The error log also references this file :-

#0 /home/website/public_html/data_objects/do_catalogue.php(68): DbManager->DbGetAll('SELECT p.code, ...')
#1 /home/website/public_html/smarty_plugins/function.load_search.php(38): DoCatalogue->SearchProducts(Array)
#2 /home/website/public_html/smarty_plugins/function.load_search.php(5): Search->init()

But I ***think*** that is just because the above query is incorrect?

Thank you for any help in fixing this error.

Ok, this is rather bizarre. First this code...
            if($postCount > 0)
            {
                $i = 0;
                while($row = $this->db->fetch_assoc($post_pagination->resource()))
                {
                //    echo $row['post_message'];
                    $content .= ($i % 2 == 0 ? '<tr class="odd">' : '<tr>');
                    $content .= '<table>';
                    $content .= '<tr><td>'.$row['username'].'</td></tr>';
                    $content .= '<tr>';
                    $content .= '<td><p>'.$row['post_message'].'</p></td>';
                    $content .= '</tr>';
                    $content .= '</table>';
                    $content .= '</tr>';
                    $i++;
                }
                $content .= '<tr><td>| '.$plinks.' |</td></tr>';
            }

For whatever reason, if I comment out the line with $row['post_message'] everything works as expected. If I leave that in there like it is now, I get a completely blank white page.

I've also tried assigning it to a variable within the loop like...
$post_message = $row['post_message'];
and that works fine, until I try echo'ing it then the same blank white page result.

I've double checked the query, both in PHP and in PHPMyAdmin and it is working correctly.

Here's the query code:
            $post_pagination = new pagination($ppg, "SELECT `posts`.`post_id`, `posts`.`post_message`, `cg_accounts`.`id`, `cg_accounts`.`username`
                                       FROM `".$this->dbname."`.`threads`, `".$this->dbname."`.`posts`
                                       INNER JOIN `crikeyga_central`.`cg_accounts` ON (`cg_accounts`.`id` = `posts`.`userid`)
                                       WHERE `posts`.`thread_id`=`threads`.`thread_id`
                                       AND `posts`.`thread_id`='".$thread_id."'
                                       ORDER BY `posts`.`post_timestamp` ASC");
I've also double checked the pagination class is working as expected, and it's fine in every other page it's used in. Also $ppg is the correct value(simply holds the current page number). $this->dbname is also correct, and as mentioned above the query works in PHPMyAdmin.

And $post_pagination->resource() is holding the correct value and I've checked the database class in particular $this->db->fetch_assoc() and that's working fine.

Really not having much luck pinning this one down, no errors are coming up(error reporting(E_ALL)).

seems strange to me that $row['username'] comes up fine, but $row['post_message'] results in a white page. The values are also what they should be.

Any help is appreciated!

Thanks, Ace

What the script does:

if the page is ?event=edit, it lists all the available events.

If not, it checks what event id is at ?event and lists that ID from the DB.

What's wrong with it?

Thanks

Hey.   So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:

$firstArray = array(
'row1' => array(
'dates' => array(
'2014-01-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),
'2014-01-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

)
)
);

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each.   And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..

$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}

Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested.   This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance.   In short my question is, are there any better methods of handling this with the data setup we currently have?

Hi. I am a little confused about PDO, its classes and the general oop aspects of it. If you at the below code:  

<?php

try {
$handler = new PDO('mysql:host=127.0.01;dbname=app', 'root','');
$handlser->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

}catc(PDOException $e) {
echo $e->getMessage():
die();

}

$query = $handler->query('SELECT * FROM table');

while($r = $query->fetch(PDO::FETCH_OBJ)) {

echo $r->message;

}

What's confusing me is that the fetch method is a method within the PDOSTATEMENT class so how come an object hasn't been created before hand in order to use the method? Furthermore it appears the method is a static method within the PDOSTATEMENT class so how come the double semi colon is being used such as: PDOSTATEMENT::FETCH?

Any help would be appreciated. Thanks.

Okay so, I have always been curious, just never have taken the time to ask someone / learn what the differences are in fetches. What does mysql_fetch_array and mysql_fetch_row do thats different from each other? When pulling data from the database, would I like fetch array, or fetch row? or even fetch assoc? Thanks!

I have this code and Im using a while to fetch all the data where users comments are but i want to change it to fetch only 25 rows at a time and each time it refreshes it fetch's 25 more different rows.
Code: [Select]
<?php
include "../../connect.php";
Header('Cache-Control: no-cache');
Header('Pragma: no-cache');
$username = mysql_real_escape_string($_GET['username']);
//If friend is set, then query for it, otherwise return all of the friends comments.
$friend = (isset($_GET['friend'])) ? ' AND b.friend = \'' . mysql_real_escape_string($_GET['friend']) . '\' ' : NULL;

$sql = "SELECT a.username,a.comment,a.timestamp,a.title,a.picture,a.pic_status,a.pic_url,b.id,c.avatar,c.atimestamp,c.onlinestatus FROM (user_comments as a JOIN accounts as c USING(username))JOIN `user_friends_list` as b ON (b.friend = a.username)WHERE (b.username = '$username' $friend AND b.status = 1) ORDER BY a.id DESC";

$result = mysql_query($sql);
$user_xml = "<?xml version=\"1.0\"?>\n";
//$user_xml .= "<root>\n";
if(mysql_num_rows($result) > 0)
{ 
while ($row = mysql_fetch_assoc($result))
{       
$user_xml .= "<comment>\n";
$user_xml .= "<image>" . $row['avatar'] . "</image>\n";
$user_xml .= "<name>" . $row['username'] . "</name>\n";
$user_xml .= "<text>\n";
$user_xml .= "<![CDATA[ ". $row['comment'] ."]]>\n";
$user_xml .= "</text>\n";
$user_xml .= "<time>" . $row['timestamp'] . "</time>\n";
$user_xml .= "<title>" . $row['title'] . "</title>\n";
$user_xml .= "<picture>" . $row['picture'] . "</picture>\n";
$user_xml .= "<status>" . $row['pic_status'] . "</status>\n";
$user_xml .= "<url>" . $row['pic_url'] . "</url>\n";
$user_xml .= "<ntimestamp>" . $row['atimestamp'] . "</ntimestamp>\n";
$user_xml .= "<online>" . $row['onlinestatus'] . "</online>\n";
$user_xml .= "</comment>\n";
}
}
//$user_xml .= "</root>\n";

echo $user_xml; 
?>

So i think i can do something like this but im not to sure.

just add a if statement

Code: [Select]
while ($row = mysql_fetch_assoc($result))
{


$user_xml .= "<comment>\n";
$user_xml .= "<image>" . $row['avatar'] . "</image>\n";
$user_xml .= "<name>" . $row['username'] . "</name>\n";
$user_xml .= "<text>\n";
$user_xml .= "<![CDATA[ ". $row['comment'] ."]]>\n";
$user_xml .= "</text>\n";
$user_xml .= "<time>" . $row['timestamp'] . "</time>\n";
$user_xml .= "<title>" . $row['title'] . "</title>\n";
$user_xml .= "<picture>" . $row['picture'] . "</picture>\n";

I only wnat to read 25 comments at a time and when i click a button to read more then it reads 25 more rows but it dose not read the data unless requested... can any one help me?

There is a school locator script at https://www.ocps.net/parents/pages/FindaSchool.aspx
When we input any address it returns schools located in that locality.

For example:

Use these details and submit the form

Street Number : 3902
Street Name   : Bobolink
Street Type   : Lane
City         : Orlando


It returns a row having three schools Elementary,Middle and High school
On clicking the more button it takes to the respective school details
So for each school I need the respective school names

Audobon Elementary
Glenridge Middle
Winter Park High

Please suggest some ways to achieve this functionality


Thanks

Hello,

Can I set the priority on my scripts relating to swap? Something like set_swap(10); would mean that it will be first to go into swap and set_swap(1) means it will go as a last resort and set_swap(5) being the default ?

Kind of like the proc_nice() but for memory ?

Thanks,

David
