PHP - Json_decode Return Instance Of Person Class
json_decode returns a stdClass Object.
Is there any way where I can get instance of my class instead of the same? I mean If I json_decode the below string then it will provide me instance of stdClass and not instance of Person class {"name":"a"} How to achieve the same? Thanks in advance CSJakharia Similar TutorialsI've been looking everywhere for a solution of this but I can't find one...
Basically what I did was created a class named USER.
public class USER{
private static $USER = array();
public function __construct($U='')
{
// if $U is not entered (=='') then set $U to MY USER ID ($_COOKIE['user'])
// do a mysql query by the ID (ala $U) and store the results to self::$USER
}
public function ID()
{
return self::$USER['id'];
}
}
This is the code I am running...
I do a user profile page that shows different properties of the USER from the database: USERNAME(),ID(),PHONE(),EMAIL(), etc. etc.
// creates an instance of a different user (other than myself) $PROFILE = new USER($ID); // $ID: 26 will retrieve USERNAME: Test // create an instance of user class for myself using the cookie holding my id $ME = new USER($_COOKIE['user']) // $_COOKIE['user']: 01 will retrieve USERNAME: Monster echo($PROFILE->USERNAME()); // displays Monster echo($PROFILE->ID()); // displays 01Any idea what I am doing wrong? I would assume that $PROFILE->USERNAME() would display Test and $ME->USERNAME() would show monster. I have an existing instance of my class Database, now I want to call that instance in my Session class, how would I go about doing this? Hi All
I have not really played around with PHP in ages so I am having a hard time trying to figure out the best way to proceed. Anyhow... what I need to get done is to take a singleton pattern core database class that has a extended driver based class (ie; the type of database server the connection is connecting to), and build a new class that dynamically handles as many driver based connections that are called using a single instance. As a side note, I tried PDO but it only supports a single driver per class instance, and then each of those connections cannot not have their on set of properties that relate to each connection. Anyway, I was thinking that the best way to handle all the driver specific connections, is to hand out a 'unique hash reference' that points to an array of connection objects and the object properties. then when the client runs any sql function they pass the 'unique hash reference' which the class then returns the object and it properties that will be used by the class to call up the driver specific sql function that was requested by the client. So what do you all thing about that....
TIA stephanieT
PS...
I reason i need this is because I need to update up 25 different databases based on data stored on all the databases and not all of the database servers are of the same type, (ie; MSSQL, Oracle, MySQL, MariaDB, berkeley DB, postgres, sqlite2,3, etc, etc)! Edited January 16, 2019 by StephanieTHey, I've not used PHP for a while and never really used classes! I was reading some code today and I saw a statement something like: Code: [Select] $s = &MyClass::("Something"); From reading the PHP Manual it has an example which looks like this for 5.3, however my server still uses 5.2 (.9), how do I do similar using that? Preferably something along these lines... Code: [Select] class spook{ function __construct($n){ if($n==1){ return "hello"; } else { return "goodbye"; } } } $a=spook::(); print $a; Cheers! i.e. What was the old method before the Scope resolution operator? Script:
<?php
class Article{
public function fetch_all(){
global $pdo;
$query = $pdo->prepare("SELECT * FROM `articles` ORDER BY `article_timestamp` DESC");
$query->execute();
return $query->fetchAll();
}
public function fetch_data($article_id){
global $pdo;
$query = $pdo->prepare("SELECT * FROM `articles` WHERE `article_id` = ?");
$query->bindValue(1, $article_id);
$query->execute();
return $query->fetch();
}
/*
* These have gotten added later on.
*/
public function delete($id){
global $pdo;
$query = $pdo->prepare("DELETE FROM `articles` WHERE `article_id` = ?");
$query->bindValue(1, $id);
$query->execute();
// The "return" here.
}
public function edit_page($title, $content, $aticle_id){
global $pdo;
$query = $pdo->prepare("UPDATE `articles` SET `article_title` = ?, `article_content` = ? WHERE `article_id` = ?");
$query->bindValue(1, $title);
$query->bindValue(2, $content);
$query->bindValue(3, $article_id);
$query->execute();
// The "return" here.
}
}
?>
I have this from a tutorial. In the function "fetch_all()" it uses "fetchAll()" at the spot where the "return" is, and in the function "fetch_data()" it uses "fetch()" at the spot where the "return" is.
My Question:
What may have to use for the function "delete()" and the function "edit_page()" at the spot where "return" would be?
Edited by glassfish, 29 October 2014 - 12:32 PM. Hi I have a problem with the following: Code: [Select] <?php class ClassA { public $propertyClassName = "ClassB"; public function methodClassName() { return "ClassB"; } } class ClassB { public function bmethod() { echo "great!"; } } //works $a = new ClassA(); $b = new $a->propertyClassName(); $b->bmethod(); //doesn't work $a = new ClassA(); $b = new $a->methodClassName(); $b->bmethod(); ?> Of course I could do Code: [Select] <?php $a = new ClassA(); $className = $a->methodClassName(); $b = new $className; $b->bmethod(); ?>but isn't there a way to do this without saving the method's return to a variable? Thanks in advance flolam Hey guys, So im building a Content Management System for my A2 project in Computing, and i have a dataBase class. Now, i can return one thing, or do things like inserts however im having a problem returning a list of things such as: dataBase.class.php Code: [Select] public static function getNYCPost($table, $limit) { dataBase::_dbConnect(); if($limit == 0) { //debug: echo 'in as 0'; $data = mysql_query("SELECT id, linklabel FROM ".$table." WHERE showing='1' AND id >= 2"); } if($limit == 1) { //debug: echo 'in'; $data = mysql_query("SELECT id, linklabel FROM ". $table ." WHERE showing='1' AND id >= 2 ORDER BY id DESC LIMIT 5"); return $data; } } When i try to do this in the main code: index.php Code: [Select] <?php $list = dataBase::getNYCPost($pages,1); // echo $list; while ($row = mysql_fetch_array($list)) { $pageId = $row["id"]; $linklabel = $row["linklabel"]; $menuDisplay .= '<a href="index.php?pid=' . $pid . '">' . $linklabel . '</a><br />'; } echo $menuDisplay; ?> $list doesnt return anything, the previous method i used in the class was to make a list and an array and put the contents of the query in an array like: Code: [Select] list($list[] = $row); or something i cant quite remember i saw a youtube video tutorial and it worked for them, but it wasnt for me. If anyone knows how i can return various rows from a database it would be appreciated Thanks. All my code is returning is the username... Please help.

This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=350103.0 php5 I am using json_encode() to store an array of data as a string in a mysql data base. I then extract the sting from the data base and convert the back into an array using json_decode. This works great up until I have any line breaks in any of the data. When there is a line break, the json_decode() function chokes and returns nothing. I would really like to keep the line breaks. Has anyone come across this issue/have an suggestions/solutions? Hi This non php person would sure appreciate some help. My site has a simple search box. Upon searching for a keyword, it returns listings which match 1 of 10 keywords included in that specific listing- skey. $query .= " and keywords like '%$skey%' and category like '%Mycategory%'"; I would like to also have the "bname" field checked for the specific keyword and included in the listings returned. Not knowing php at all, I tried this $query .= " and keywords like '%$skey%' or '%bname%' and category like '%Mycategory%'"; and $query .= " and keywords like '%$skey%' or '%$bname%' and category like '%Mycategory%'"; which did not work. A little help with correct code would be great. Tks, Larry I have a site where people vote, currently if two computers that are on the same network vote, my site will see them as one computer because I only track people by IP address. What would be a good way to track 2+ computers with the same IP address?
