  • Reverse alphabetic sort multidimensional PHP array maintain key

    - by useyourillusiontoo
    I'm dying here, any help would be great. I've got an array that I can sort a-z on the value of a specific key but cannot sort in reverse z-a. sample of my array which i'd like to sort by ProjectName (z-a): Array ( [0] => Array ( [count] => 1 [ProjectName] => bbcjob [Postcode] => 53.471922,-2.2996078 [Sector] => Public ) [1] => Array ( [count] => 1 [ProjectName] => commercial enterprise zone [Postcode] => 53.3742081,-1.4926439 [Sector] => Public ) [2] => Array ( [count] => 1 [ProjectName] => Monkeys eat chips [Postcode] => 51.5141492,-0.2271227 [Sector] => Private the desired results would be to maintain the entire array key - value structure but with the order: Monkeys eat chips Commericial enterprise zone bbcjob I hope this makes sense

  • PHP Scale image and then create image of specific size

    - by Ronny vdb
    The result I am trying to achieve is that the user can upload an image of any size, and the server side script will convert it to an image that has the dimension 1024x512. To save the aspect ratio of the image I first scale the image down by either the width or height to match the wanted dimensions. to do this I am using imagecopyresampled(): imagecopyresampled( $new_img, $src_img, $dst_x, $dst_y, 0, 0, $new_width, $new_height, $img_width, $img_height ) && $write_image($new_img, $new_file_path, $image_quality); If we take an image that is 1920x1200 as an example, the outputted image will be 819x512. However I still need a final result of 1024x512 so I want to add white borders to the image to will the width to 1024. How can I correct my imagecopyresampled function to acheive this?

  • PHP Looping....need some advice

    - by Homer_J
    Hi all, I have the following code: $q1 = $_POST["q1"]; $q2 = $_POST["q2"]; $q3 = $_POST["q3"]; $q4 = $_POST["q4"]; $q5 = $_POST["q5"]; $q6 = $_POST["q6"]; $q7 = $_POST["q7"]; $q8 = $_POST["q8"]; At the moment, this is hard coded and I need to manually change it each time, I'd like to use variables instead so that it's not a manual process. Is it a case of using a loop, while or foreach? If I had the the information $q and q in an array would that help? Thanks, Homer.

  • Strange behavior of MySQL UPDATE query in PHP?

    - by Prashant
    When I am executing following query then its not updating views column by 1 instead sometimes its updating it by 2 or 3. Say currently views count is 24 then after executing this query it becomes 26 or sometimes its 27. $views = $views + 1; $_SQL = ''; $_SQL = 'UPDATE videos SET views = '.$views.' WHERE VideoId= "'.$videoid.'";'; @mysql_query($_SQL); I am not getting why this is happening, am I missing something or the query is executing 2 times automatically? Please help me to figure out the issue. Thanks

  • Safe image uploading with PHP

    - by directedition
    I want my site to have a feature for users to upload images, but I want to do it safely. Namely, I want to strip the EXIF data and any malicious code that could be in their image. I was thinking of a way to do this involving direct manipulation of the file, but it struck me, would it make more sense to just convert the image they provide to BMP and then convert that back to the original format? It would suffer a generational loss, but I believe that would meet my project's requirements. BMP doesn't contain EXIF, does it? And the reprocessing should strip any malicious content.

  • [PHP] strtr function OS-reltated problem

    - by Casidiablo
    Hello there! I have this funtion that converts all special chars to uppercase: function uc_latin1($str) { if(!defined("LATIN1_UC_CHARS")) define("LATIN1_UC_CHARS", "ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝ"); if(!defined("LATIN1_LC_CHARS")) define("LATIN1_LC_CHARS", "àáâãäåæçèéêëìíîïðñòóôõöøùúûüý"); $str = strtoupper ( strtr ( $str, LATIN1_LC_CHARS, LATIN1_UC_CHARS ) ); return $str; } This function works fine in my development PC (which runs Windows XP)... but, when I test it in the production server (running Redhat Linux) it does not uppercase the string. The string is ISO-8859-1 encoded. How can I make it work in Linux too? Thanks for reading.

  • php class scope when calling a non-method function not accessing all class members

    - by Aglystas
    So I'm using a stand alone function from within a class that that uses the class it's being called from. Here's the function function catalogProductLink($product_id,$product_name,$categories=true) { //This is the class that the function is called from global $STATE; if ($categories) { //The $STATE->category_id is the property I want to access, which I can't if (is_array($STATE->category_id)) { foreach($STATE->category_id as $cat_id) { if ($cat_id == 0) continue; $str .= "c$cat_id/"; } } } $str .= catalogUrlKeywords($product_name).'-p'.$product_id.'.html'; return $str; } And here's the function call, which is being made from within the $STATE class. $redirect = catalogProductLink($this->product_id, $tempProd->product_name, true, false); The object that I need access to is the $STATE object that has been declared global. Prior to this function call there are lots of public properties populated, but when I look at the $STATE object within the function scope it loses all the properties but one, product_id. The property that matters for this function is the category_id property, which is an array of category id's. I'm wondering why I don't have access to all the public properties of the $STATE object and how I can get access to them.

  • php domDocument variables

    Hi, I have the following code at the moment: $ip = '195.72.186.157'; $xmlDoc = new DOMDocument(); $xmlDoc->loadXML(file_get_contents('http://www.geoffmeierhans.com/services/geo-locator/locate/?ip='.$ip.'&output=xml')); foreach($xmlDoc->getElementsByTagName('city') as $link) { $links = array('text' => $link->nodeValue); } $city = $links['text']; echo $city; Is there a better way to get the city variable?

  • PHP problem with die()

    - by ThinkingInBits
    So, I have this code: } else { $photograph_moderation = new PhotographModeration($this->photograph_id); $photograph_moderation->purgePhotograph(); //eventually take to an error page die('image is not big enough to upload'); } the purgePhotograph() function gets called properly when this condition is met, but the script never appears to die. Is there a reason why die wouldn't get called here? purgePhotograph() has no script killing commands either.

  • How to loop an array with strings as indexes in PHP

    - by Axel Lambregts
    I had to make an array with as indexes A-Z (the alphabet). Each index had to have a value 0. So i made this array: $alfabet = array( 'A' => 0, 'B' => 0, 'C' => 0, 'D' => 0, 'E' => 0, 'F' => 0, 'G' => 0, 'H' => 0, 'I' => 0, 'J' => 0, 'K' => 0, 'L' => 0, 'M' => 0, 'N' => 0, 'O' => 0, 'P' => 0, 'Q' => 0, 'R' => 0, 'S' => 0, 'T' => 0, 'U' => 0, 'V' => 0, 'W' => 0, 'X' => 0, 'Y' => 0, 'Z' => 0 ); I also have got text from a file ($text = file_get_contents('tekst15.txt');) I have putted the chars in that file to an array: $textChars = str_split ($text); and sorted it from A-Z: sort($textChars); What i want is that (with a for loop) when he finds an A in the textChars array, the value of the other array with index A, goes up by one (so like: $alfabet[A]++; Can anyone help me with this loop? I have this atm: for($i = 0; $i <= count($textChars); $i++){ while($textChars[$i] == $alfabet[A]){ $alfabet[A]++; } } echo $alfabet[A]; Problem 1: i want to loop the alfabet array to, so now i only check for A but i want to check all indexes. Problem2: this now returns 7 for each alphabet index i try so its totally wrong :) I'm sorry about my english but thanks for your time.

  • Handling apostrophes, php and pgsql

    - by running4surival
    For my forms, I'm using pg_escape_string on every field before I insert them into the database. So I get something like firstname='O''reilly'. But when I try to print that out, I get O''reily, 2 apostrophes. Shouldn't it only 1 apostrophe, O'reilly? This isnt a debugging problem, im just wondering if you have firstname='O''reilly', how do you print that so it is just O'reilly instead of O''reilly?

  • Connect to Oracle database on a different server from PHP

    - by macha
    Hello I have a database engine sitting on a remote server, while my webserver is present locally. I have worked pretty much with client-server architecture, where the server has both the webserver and the database engine. Now I need to connect to an Oracle database which is situated on a different server. Can anybody give me any suggestions?? I believe ODBC_CONNECT might not work. Do I use OCI8 drivers?? How would I connect to my database server. Also I would have a very high number of database calls going back and forth, so is it good to go with persistent connection or do I still use individual database calls?
