PHP - New Object Syntax And Array Instance
Hi, I have an output of print_r he
Google_Service_Calendar_Acl_Resource Object
(
[stackParameters:Google_Service_Resource:private] => Array
(
[alt] => Array
(
[type] => string
[location] => query
)
[fields] => Array
(
[type] => string
[location] => query
)
[trace] => Array
I am wondering what is the right syntax to create the instance and set the variables?
Thanks,
Ted
Similar TutorialsHello, I'm attempting to build a Model View Controller and I've run into some issues with inheriting objects / extending classes. The application is focused around a "SuperObject", which contain instantiated libraries, helpers, controllers, models and views. I current have a Base class, which is effectively the "SuperObject". Previously I called the function GetInstance() within my model to get an instance of the SuperObject and assign it to a variable. So, $this->Instance->(The Object)->(The Method)(); However, I want to remove the need for that variable $this->Instance and just have $this->(The Object)->(TheMethod)(); And so, If you see my Controller class, libraries are instantiated as $this->Object which works perfectly. If from, within my controller I was to load the Model class. For example, $this->Loader->Library('Model'); when that model becomes instantiated, even though an extension of the Base class, I cannot use the libraries I instantiated in my controller. And of course there is a Fatal Error: Fatal error: Call to a member function UserAgent() on a non-object Code: [Select] <?php class Base { private static $Instance; public function Base() { self::$Instance =& $this; } public static function &GetInstance() { return self::$Instance; } } function &GetInstance() { return Base::GetInstance(); } Code: [Select] <?php class Controller extends Base { function Controller() { parent::Base(); $this->Initialize(); } function Initialize() { $Array = array( 'Uri', 'Loader', 'Router', 'Database', ); foreach($Array as $Object) { $this->$Object = loadClass($Object); } } } Code: [Select] <?php class Model extends Base { function Model() { parent::Base(); echo $this->Input->UserAgent(); } } Code: [Select] <?php class Home extends Controller { function Home() { parent::Controller(); } function index() { $this->Loader->Library('Session'); $this->Loader->Library('Model'); $Data = array( 'Controller' => $this->Router->FetchClass(), 'Title' => ucfirst($this->Router->FetchClass()) ); $this->Loader->View('meta',$Data); $this->Loader->View('header',$Data); $this->Loader->View('home'); $this->Loader->View('footer'); } } Any input would be appreciated! I know you can use str_replace to replace a value with another value, or an array of values with an array of other values. What I'd like to do is replace each instance of a single value with an array of values which get iterated through for each instance found. Think prepared statements that you don't have to call setString or setInt on. Here's a made up example. Code: [Select] $db->query = 'SELECT * FROM users WHERE user_name = ? AND user_role = ?; $db->params = array('hopelessX','admin'); $db->executeQuery(); //this contains a call to a private function that does the replace I have everything else working except this. It works if I specify an array of values to replace and do something like below, but I was hoping to not have to support that method of replace if I didn't need to. Code: [Select] $db->query = 'SELECT * FROM users WHERE user_name = :name AND user_role = :role; $db->replace = array(':name',':role'); $db->params = array('hopelessX','admin'); $db->executeQuery(); //this contains a call to a private function that does the replace I can do it that way if I need to or I could make some overly complicated thing that finds each instance of the question mark, replaces it with a unique value and then adds that unique value to a replace array similarly to the method in code block two but that defeats to the purpose of making this simple database adapter in the first place (although it was mostly just for fun anyway). Anyway, if anyone has any advice and knows of a simple means to achieve this goal that would be much appreciated. Thanks in advance I'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. *Mods* PLEASE don't move this to the OOP section again. I've had no luck there, and it's not specifically an OOP question. Hi everyone, I just want to know if there's a shorthand way to create objects, as there is for arrays: Code: [Select] // shorthand array creation $foo = array( 'bar' => 0, 'baz' => array ( 'name' => 'Dave', 'gender' => 'male' ) ) Code: [Select] // is there a way to do this with objects? // not that I know so far... $foo = object( bar->0, 'baz' -> object ( name -> 'Dave', gender -> 'male' ) ) I find object-access syntax is often quicker and easier to write than array-access syntax. Have I missed something obvious that I can't just write it out this way? Cheers, Dave Quick question, When I run the code below I get an undefined index error for the array. If I define all the indexes I have no problem making it work correctly. I thought writing it like I did below would define the indexes as they are needed. What am I doing wrong? Thanks for looking, $call_data = array(); if($call_segment['did_digits'] == '3300'){ //Check if call was answered if($call_segment['answered'] == 'No'){ $call_data['3300']['abandoned'] ++; } else{ if(in_array($call_segment['finished_on'],$phoneroom_ext)){ $call_data['3300']['phoneroom'] ++; } elseif(in_array($call_segment['finished_on'],$anoka_ext)){ $call_data['3300']['store'] ++; } } } I need to return a specific key from the object converted to array but it seems that it dosent work Code: [Select] $toarray = (array)$tmp; $name = array_keys($toarray,'name'); print_r($toarray); print:Array ( [id] => 9 [name] => dfd [text] => fdsf [rating] => 0 [totalv] => 0 ) and when i try to return the key Code: [Select] print_r($name); Array ( => rating [1] => totalv ) But I only need the key whit the 'name' value
<?php
global $places;
$comm = $GLOBALS["location"];
$comm=trim($comm);
while(list($one,$two) = each($places))
{
echo "<option value=\"$two\"";
if ( $two == $comm)echo "selected ";
echo ">$two</option>\n" ;
}
?>
Variable passed to each() is not an array or objectHi, my code works fine but it is giving the error message Please can anyone help? Thanks ok .. so I have this object and I want to make a tab delimited text file from it. here's what I have so far. function create_tab_file_from_object($the_object) { $string = ''; foreach($the_object as $val) { $string .= $val.'\t'; } //drop last tab $string = substr($string,0,-2); filename = 'test_file_pickup.txt'; $fp = fopen('/filepath/'.$filename,'w'); fwrite($fp,$string); fclose($fp); } when i run this i get a text file that looks something like this field1\tfield2\tfield3\t ... and so on. How do I get php to make an actual tab delimited file I can open in notepad or excel or whatever..

Thanks in advance hi, very strange issue. when I create test e-mail or I will forward the specific e-mail, the script works correctly - saves attachment into server disk. now, when I configure to check another mailbox, it gives me error: Num Messages 11 Fatal error: Cannot use object of type stdClass as array in /test/emailattach/index.php on line 34 index.php: Code: [Select] <?php $mbox = imap_open("{mail.server.com:143}", "email@email", "XXX") or die('Cannot connect to mail: ' . imap_last_error()); // make connection with mailbox and check # messages if ($hdr = imap_check($mbox)) { echo "Num Messages " . $hdr->Nmsgs ."\n\n<br><br>"; $msgCount = $hdr->Nmsgs; } else { echo "failed"; } $overview=imap_fetch_overview($mbox,"1:$msgCount",0); $size=sizeof($overview); // get message info for($i=$size-1;$i>=0;$i--) { $val=$overview[$i]; $msg=$val->msgno; $from=$val->from; $date=$val->date; $subj=$val->subject; $seen=$val->seen; $from = ereg_replace("\"","",$from); // Check for attachements and store them $struct = imap_fetchstructure($mbox,$msg); $contentParts = count($struct->parts); if ($contentParts >= 2) { for ($ix=2;$ix<=$contentParts;$ix++) { $att[$ix-2] = imap_bodystruct($mbox,$msg,$ix); } for ($k=0;$k<sizeof($att);$k++) { if ($att[$k]->parameters[0]->value == "us-ascii" || $att[$k]->parameters[0]->value == "US-ASCII") { if ($att[$k]->parameters[1]->value != "") { $FileName[$k] = $att[$k]->parameters[1]->value; $FileType[$k] = strrev(substr(strrev($FileName[$k]),0,4)); } } elseif ($att[$k]->parameters[0]->value != "iso-8859-1" && $att[$k]->parameters[0]->value != "ISO-8859-1") { $FileName[$k] = $att[$k]->parameters[0]->value; $FileType[$k] = strrev(substr(strrev($FileName[$k]),0,4)); $fileContent = imap_fetchbody($mbox,$msg,$file+2); $fileContent = imap_base64($fileContent); $localfile = fopen("$FileName[$k]","w"); fputs($localfile,$fileContent); fclose($localfile); } } } } imap_close($mbox); ?> Could there be some encoding issue? with thanks, Margus There's probably an obvious reason but I can't seem to find it... I start with the $_POST array, received from a form: Code: [Select] array(9) { ["Name"]=> string(3) "KTN" ["SQLServer"]=> string(24) "10.6.11.20\VSQLI028,1433" ["Username"]=> string(2) "GF" ["Password"]=> string(2) "GF" ["MasterDB"]=> string(11) "GFMaster_KN" ["Version"]=> string(3) "4.9" ["Prod"]=> string(1) "1" ["Monitored"]=> string(1) "0" ["button"]=> string(38) "updateColumnName=EnvironmentID;Value=1" } I get the button value from the array, and unset the button array value. Code: [Select] function load_POST($name) { //returns value and removes it from $_POST array. returns NULL if not existing. $debug = 0; if ( $debug == 1 ) { $backtrace = backtrace(); echo __FUNCTION__."()"; echo " <i>called by ".basename($backtrace[1]['file'])."</i><br/>\n"; } $post = NULL; if( array_key_exists($name, $_POST) ) { $post = urldecode($_POST[$name]); if ( $debug == 1 ) { echo "post $name, value: $post<br/>\n"; } } else { if ( $debug == 1 ) { echo "post $name: doesn't exist<br/>\n"; } } unset($_POST[$name]); return $post; } $_POST is now: Code: [Select] array(8) { ["Name"]=> string(3) "KTN" ["SQLServer"]=> string(24) "10.6.11.20\VSQLI028,1433" ["Username"]=> string(2) "GF" ["Password"]=> string(2) "GF" ["MasterDB"]=> string(11) "GFMaster_KN" ["Version"]=> string(3) "4.9" ["Prod"]=> string(1) "1" ["Monitored"]=> string(1) "0" } Then I create the object to assign the values to: Code: [Select] object(Environment)#1 (9) { ["EnvironmentID"]=> NULL ["Name"]=> NULL ["SQLServer"]=> NULL ["Username"]=> NULL ["Password"]=> NULL ["MasterDB"]=> NULL ["Version"]=> NULL ["Prod"]=> int(0) ["Monitored"]=> int(0) } So far so good Then, for each remaining $_POST value, I update the Object accordingly: First one, parametername: Name, parameter: KTN Code: [Select] object(Environment)#1 (10) { ["EnvironmentID"]=> NULL ["Name"]=> string(3) "KTN" ["SQLServer"]=> NULL ["Username"]=> NULL ["Password"]=> NULL ["MasterDB"]=> NULL ["Version"]=> NULL ["Prod"]=> int(0) ["Monitored"]=> int(0) ["ColumnName=EnvironmentID;Value=1"]=> object(stdClass)#3 (1) { ["ColumnName"]=> string(1) "1" } } And there we have the problem, for some reason the button value is added to the object somehow... Any ideas? Thanks in advance! I'm trying to make my register script check the database's IP column and compare it with the user's IP. If the User's IP equals that in the DB column, it should say "Sorry, there is already an account registered with your IP Address. Please log in.", and if there's no IP match, it should allow them to continue with registering. I've been tinkering around with this for a while and I can't seem to figure it out. Any help would be appreciated if ($_SERVER['REMOTE_ADDR'] == mysql_query("SELECT ip FROM users")) { die('Sorry, there is already an account registered with your IP Address. Please <a href="/login.php>log in.</a>'); }else{ echo ''; } I think the problem is with the mySQL query... Hey Guys. I have a shopping cart script that loops through the shopping cart session array and assigns values to the property of a class. For some weird reason the subtotal property only works when I use the self keyword. If I use the $this-> instance variable the sub total does not get assigned the subtoal price. Its just NULL.
Does anyone have any suggestions as to why it may not be working.
Below is a quick copy and paste of my code. Please be aware that some there may be some syntax mistakes as a result to copying and pasting part of my code that is relevant to this issue. Thanks!
class CoreCartFunctions {
protected static $subtotal;
protected $menu_item_price = NULL;
public function GetMenuItem() {
//self:items is the cart session array that is initilized in a construct method
//Assign the values for each cart array
foreach (self::$items as $menu_item_id_session) {
$this->menu_item_price = getItems($this->menu_item_id,"menu_item_price")*$this->item_qty;
self::$subtotal += $this->menu_item_price;
//Does not work with the following ---> $this->subtotal += $this->menu_item_price;
}
}
So, I have what I think is an odd question. I have a function that contains a for loop. Within that for loop, it checks for a new condition and if it is true, it calls the very function it's already in. So, within the for loop inside of function "a", it can call function "a" with new arguments which will then start a new for loop to be "nested" to the previous for loop, in a way. My problem is trying to keep the values of the variables so that once the new for loop (or loops) finish, the previous for loop won't be stopped up by the new variable values that have since changed. Make sense? So, two questions: 1. How do I lock in values that make them unique to that very call of that function and keep them unique through further iterated versions? 2. I imagine, in theory, that for loops stay in memory in state as a new "instance" of that same for loop runs through, right? Basically, is what I'm doing possible in that a for loop calls itself, in essence, to create a new "instance" of that for loop, then when it finishes, have the previous loop continue iterating? For question #1, I've already thought about using variable variables, but that doesn't work because every time the function is called, the variable variable will change to new values based on the new arguments and instantiating the function again. I'm kind of looking for a way to make unique "instances" of a method that don't mess with future calls to that method and where future calls don't mess with currently iterating loops in that method. Phew, I think I confused myself. Thanks for any help. Hey, I'm trying to save a MySQL-Link source as an instance variable in my query class. The problem is that MySQL sees it as an invalid MySQL-Link (supplied argument is not a valid MySQL-Link resource). What I'm I doing wrong? //Walle Code: [Select] private $connection; //Construct public function __construct(&$connection) { $this->connection = $connection; } //Where the error occurs public function exe_query($sql) { $result = mysql_query($sql, $this->connection); if(!$result) { throw new Exception(mysql_error()); } return $result; } Hello, I need to find the target html address within some raw html. I know it lies between Needle 1 and Needle 2 below. Needle 1: </span></a> <a href=" Needle 2: " rel="nofollow"><span class=pn><span class=np>Next »</span></span></a></div> Nornally I would just use the explode() function but my headache is that there are many instances of Needle 1 in the raw html code and I want my output array always have the same number of elements. However I do know that my target html address is directly after the last instance of Needle 1. How should I go about splitting the html code into an array that always has 3 elements? I'd like the first element to include code up to and including the last instance of Needle 2, the 2nd element to have the target html address, and the 3rd element to have Needle 2 and any following code. Thanks for any pointers (my main struggle is identifying the last instance of needle 1), Thanks, Stu Hope someone can help, I am trying to add up all the values of a variable in a PHP while loop and have tried several approaches but none seem to work. Hopefully someone can point out what the correct method is. I've set up some code to pull the pay rate from a MySQL table, and then calculate that person's earnings based on the amount of time they spend on a particular job. That works fine:
However there may be a number of jobs for different people with different rates, so I want to add all of these up and output the total. So for example if I had values of 125.00, 35.50 and 22.75 I want to show 183.25 as the total. So I tried a few things I found on forums on the subject:
That didn't work so I tried another method that someone suggested:
The 2nd method outputted just the last individual value, the 1st method didn't work at all. Does anyone have a working method that can be used to do this? Thanks |
