  • [PHP] access array element by value

    - by Brandon
    array( [0] name => 'joe' size => 'large' [1] name => 'bill' size => 'small' ) I think i'm being thick, but to get the attributes of an array element if I know the value of one of the keys, I'm first looping through the elements to find the right one. foreach($array as $item){ if ($item['name'] == 'joe'){ #operations on $item } } I'm aware that this is probably very poor, but I am fairly new and am looking for a way to access this element directly by value. Or do I need the key? Thanks, Brandon

  • Saving generated .wav file to server with PHP

    - by bionicOnion
    I am developing a website where users can compose their own music, and the site will generate a .wav file for their creation. This is working correctly (inasmuch as I can play it on the page). However, I would like to save this file to the server to be listened to/downloaded at a later time, and the saved version of the file can no longer be opened and played by the HTML audio tag. What, if anything, must I put into the file besides the file besides the raw data? Instead of setting the src attribute of the audio tag to the location of the file, will I actually need to open it and generate a URI?

  • PHP check if file exists on my server, based on a full URL

    - by stef
    I have an app that generates invoices in the form of PDF files stored in a directory on my server. Before mailing out this invoices I'd like to make sure that the URL (not server path) which I store in my DB does indeed point to a valid PDF file. Something could have gone wrong that wrote a value to that field in the db, but for example the filename is missing; meaning the file is not in the specified directory. AFAIK file_exists just checks server paths but not URL's. I could always store the server path too, or assemble it, but I'm wondering if i can do this check based on a full http url ending with a filename? EDIT: yeah CURL occurred to me too but doesn't that seem a bit heavy for such a simple task? Perhaps I should just store the server path too.

  • Entity-attribute-value model using codeigniter / php

    - by John Stewart
    SO I am trying to create a way to structure my database to be able customize forms. I looked into EAV pattern and here is my db structure: Table form - form_id - form_name - form_added_on - form_modified_at Table: form_fields - field_id - form_id - field_type (TEXT, RADIO etc..) - field_default_value - field_required Table: form_data - data_id - field_id - form_id - field_value so now I can store any custom form into the database and if I want to get the values for an individual form I can simply join it by "form_id" .. the problem: I want to be able to search through all the forms for a specific field value. How can I do that with EAV model? Also, I thought about just storing the custom data as a serialized (JSON) object but then I am not sure how can I query that data. Please note that I am using Codeigniter with MYSQL. So if conversation can use Codeigniter libraries if needed.

  • PHP anonymous functions scope question

    - by Dan
    Hi, I'm trying to sort an array of objects by a common property, however I cannot get my $property parameter to register in the inner function (I can use it in the outer one OK). The way I read the documentation, it sounded like the parameter would be available, have I misunderstood something? Here is what I have: public static function sortObjectsByProperty($objects, $property) { function compare_object($a, $b) { $a = $a->$property; $b = $b->$property; if ($a->$property == $b->$property) { return 0; } return ($a->$property > $b->$property) ? +1 : -1; } usort($objects, 'compare_object'); return $objects; } Any advice appreciated. Thanks.

  • Dynamic inheritance/implementation in PHP 5.*

    - by Rolf
    Hi everyone, I'm implementing a Logger, based on a XML declaration (path to class, method name, custom log message). There is also a Logger interface that defines the function __call, the latter logs what's needed and then relays the call to the target method. The only difficulty is to make each class, declared in the XML file, implement this interface with __call. So finally my question: is there a way to set at runtime the parent class or the implemented interface of another class ? Thanks in advance ! Rolf

  • How Easy Is It to Hijack Session Vars on GoDaddy (PHP)

    - by yar
    This article states that If your site is run on a shared Web server, be aware that any session variables can easily be viewed by any other users on the same server. On a larger host like GoDaddy, are there really no protections in place against this? Could it really be that easy? If it is that easy, where are the session vars of the other users on my host so I can check them out? Edit: I didn't believe it, but here's my little program which shows that this is true! I wonder if those are really the same as the value stored in the cookies on the users' machine?

  • Lamda functions in php

    - by Oden
    Hey, Im really interested in the way of using lamda functions. Does it make sense to use them in a high-level programming language? If yes, why? Is this really just a function embedded in a function, (Like this) or is there more behind?

  • PHP MVC Principles

    - by George
    I'm not using an off-the-shelf framework and don't particularly want to (nor d I want to go into the reasons why...). Anyway, onto my question(s), I hope it make sense.... I'm trying to get my head around what should go in the model and what should go in the controller. Originally I had the impression that a model class should represent an actual object (eg - a car from the cars table of a database) and model properties should mirror the database fields. However I'm now getting the feeling that I've got the wrong idea - should an instance of a model class represent an actual item, or should it contain a number of methods for doing stuff - sometimes to one car or sometimes to multiple cars based on my example earlier. For example I want to get all the cars from a the database and show them in the view. Am I right in think it should be along the lines of this? Controller File function list() { $cars = $this->model->get_all(); $this->view->add($cars); $this->view->render('cars-list'); } Model File function get_all() { // Use a database interaction class that I've written $cars = Database::select(); return $cars; } Now, if the car had a "status" field that was stored as an integer in the database and I wanted to change that to a string, where should that be done? By looping the SQL results array in the get_all() method in the model? Also, where should form validation live? I have written a validation class that works a little like this: $validator = new Validator(); $validator->check('field_name', 'required'); If the check fails, it adds an error message to the array in the Validator. This array of error messages would then get passed to the view. Should the use of my validator class go in model or the controller? Thanks in advance for for any help anyone can offer. If you know of any links to a simple MVC example / open source application that deals with basic CRUD, they would be much appreciated.

  • PHP Simple_html_dom issue

    - by stef
    The snippet below loops through some web pages, grabs the html and then looks for table.results and gets the plaintext out of the tags contained in each . $results is ok. Now I'm trying to get the href value of an tag that is found in the second of each . I'd like to include this in the $results array, but I'm not sure how to do this. The third foreach statement gets them but then I need to merge $links with $results. Ideally I'd also get the links in the second foreach statement. Does anyone know how? $i = 0; foreach( $urls as $u ) { $html = file_get_html($u); foreach($html->find('.results tbody tr') as $element) { $result[$i] = $this->extract($element->plaintext); $i++; } foreach($html->find('.results tbody tr a') as $element) { $links[$i] = $element->href; $i++; } } print_r($result); print_r($links); die;

  • How to simplify my country select menu PHP/mysql

    - by user342391
    I have a select menu that displays countries. It looks at the DB and judging by the value in the db shows the option as selected. Is there a simpler way off doing this than: if ($country == 'AG') {echo '<option value="AG" selected="selected">Antigua</option>';} else {echo '<option value="AG">Antigua</option>';}; if ($country == 'AR') {echo '<option value="AR" selected="selected">Argentina</option>';} else {echo '<option value="AR">Argentina</option>';}; if ($country == 'AM') {echo '<option value="AM" selected="selected">Armenia</option>';} else {echo '<option value="AM">Armenia</option>';}; if ($country == 'AW') {echo '<option value="AW" selected="selected">Aruba</option>';} else {echo '<option value="AW">Aruba</option>';}; if ($country == 'AU') {echo '<option value="AU" selected="selected">Australia</option>';} else {echo '<option value="AU">Australia</option >';}; if ($country == 'AT') {echo '<option value="AT" selected="selected">Austria</option>';} else {echo '<option value="AT">Austria</option>';}; if ($country == 'AZ') {echo '<option value="AZ" selected="selected">Azerbaijan</option>';} else {echo '<option value="AZ">Azerbaijan</option>';}; if ($country == 'BS') {echo '<option value="BS" selected="selected">Bahamas</option>';} else {echo '<option value="BS">Bahamas</option>';}; if ($country == 'BH') {echo '<option value="BH" selected="selected">Bahrain</option>';} else {echo '<option value="BH">Bahrain</option>';}; There are a lot of countries and doing this would be madness wouldn't it????
