  • PHP/XPath: Iterating through ancestor nodes in XML using SimpleXML

    - by StackOverflowNewbie
    I need to loop through the Ancestors nodes in order to get corresponding BrowseNodeId and Name values. How do I do this using XPath? I'm trying something like the the following, but it's not working: //BrowseNode[1]//Ancestors[1]/BrowseNode/BrowseNodeId/text() //BrowseNode[1]//Ancestors[1]/BrowseNode/Name/text() I think the //Ancestors part of the XPath is actually searching the entire XML tree. What I need to do is visit each node to get the needed values. How do I do this? In the example below, I want: Europe - History - Subjects - Books. Example XML: <BrowseNode> <BrowseNodeId>4952</BrowseNodeId> <Name>France</Name> <Ancestors> <BrowseNode> <BrowseNodeId>4935</BrowseNodeId> <Name>Europe</Name> <Ancestors> <BrowseNode> <BrowseNodeId>9</BrowseNodeId> <Name>History</Name> <Ancestors> <BrowseNode> <BrowseNodeId>1000</BrowseNodeId> <Name>Subjects</Name> <IsCategoryRoot>1</IsCategoryRoot> <Ancestors> <BrowseNode> <BrowseNodeId>283155</BrowseNodeId> <Name>Books</Name> </BrowseNode> </Ancestors> </BrowseNode> </Ancestors> </BrowseNode> </Ancestors> </BrowseNode> </Ancestors> </BrowseNode>

  • [PHP] Dynamic cron jobs?

    - by Frankie Laguna
    I'm writing a script that needs to be called at a random time during the day, but am not sure how to accomplish this. I don't want to waste server resources to run a cron job every minute. I want the script to be called at random, so generating the random times for say a month in advance and then creating cron jobs for each of them isn't what I'm looking for. Also this script only needs to be executed once a day. Thanks in advance!

  • 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

  • Getting the names of all files in a directory with PHP

    - by Greelmo
    For some reason, I keep getting a '1' for the file names with this code: if (is_dir($log_directory)) { if ($handle = opendir($log_directory)) { while($file = readdir($handle) !== FALSE) { $results_array[] = $file; } closedir($handle); } } When I echo each element in $results_array, I get a bunch of '1's, not the name of the file. How do I get the name of the files?

  • PHP array pointer craziness

    - by JMan
    I'm trying to create a "GetCurrentLevel" method that takes a point value as an input and returns what "Level" that corresponds to. I'm storing the Level = Points mapping in an array, but the array pointer is not moving logically when I use it a foreach loop. I've added echo statements for debugging. Here's my class definition: class Levels extends Model { protected $_map = array ( 'None' => 0, 'Bronze' => 50, 'Silver' => 200, 'Gold' => 500 ); public function __construct() { parent::__construct(); } public function GetCurrentLevel($points) { foreach ($this->_map as $name => $threshold) { echo "Level Name: $name<br/>"; echo "Level Threshold: $threshold<br/>"; echo "Current Level: " . key($this->_map) . "<br/>"; echo "Current Threshold: " . current($this->_map) . "<br/>"; if ($points < $threshold) /* Threshold is now above the points, so need to go back one level */ { $previousThreshold = prev($this->_map); echo "Previous Threshold: $previousThreshold<br/>"; echo "Final Level: " . key($this->_map) . "<br/>"; return key($this->_map); } echo "Go to next level <br/>"; } } And here is what I see when I call GetCurrentLevel(60): Level Name: None Level Threshold: 0 Current Level: Bronze //* Looks like foreach immediately moves the array pointer *// Current Threshold: 50 Go to next level Level Name: Bronze Level Threshold: 50 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Go to next level Level Name: Silver Level Threshold: 200 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Previous Threshold: 0 Final Level: None But the "Final Level" should be 'Bronze' since 60 points is above the 50 points needed for a Bronze medal, but below the 200 points needed for a Silver medal. Sorry for the long post. Thanks for your help!

  • <?php echo $questionTitle; ?> [closed]

    - by oil
    So this "question" makes no sense and will be closed. But are you willing to spend your hard-earned reputation to downvote it? Go on. A programmer should be able to make logical decisions, why will you downvote the question then instead of ignoring it?

  • php: simplexml exception retry

    - by exceptionhandlingnoob
    I am querying an API using SimpleXML which will occasionally fail for reasons unknown. I would like to have the script retry up to 5 times. How can I do this? I assume it has something to do with wrapping the object in a try/catch, but I'm not very experienced with this -- have tried to read the manual on exception handling but am still at a loss. Thanks for any help :) // set up xml handler $xmlstr = file_get_contents($request); $xml = new SimpleXMLElement($xmlstr); Here is the error message I am receiving: [function.file-get-contents]: failed to open stream: HTTP request failed!

  • Getting an non-object error in my php script

    - by Disowned
    Hey I was trying to call a script to made some changes to an html file, however when I run the script it tells me that it's making a call to a non-object. Obviously I did something wrong, but what? Here's the script. /*Dom controllers*/ $dom = new DOMDocument(); $dom->loadHTML('index.html'); $id = $dom->getElementById('contact_us'); $p = $dom->appendChild(new DOMElement('p')); $op = $dom->getElementsByTagName('p'); /* Dem POST vars used by dat Ajax mah ziggen, yeah boi*/ if (isset($_POST['Home']) && isset($_POST['About']) && isset($_POST['Contact']) && isset($_POST['sexyText'])){ $home = $_POST['Home']; $about = $_POST['About']; $contact = $_POST['Contact']; $text = $_POST['sexyText']; trim($home); trim($about); trim($contact); trim($text); } function post(){ global $dom, $id, $home, $about, $contact, $text, $textp, $p, $op; $textp = $dom->createTextNode($text); $p->appendChild($textp); $id->replaceChild($p, $op); $dom->saveHTMLFile('index.html'); } post(); echo 1; ?> The error happens at the replaceChild function.

  • PHP, MySQL prepared statements - can you use results of execute more than once by calling data_seek(

    - by Carvell Fenton
    Hello, I have a case where I want to use the results of a prepared statement more than once in a nested loop. The outer loop processes the results of another query, and the inner loop is the results of the prepared statement query. So the code would be something like this (just "pseudoish" to demonstrate the concept): // not showing the outer query, it is just a basic SELECT, not prepared statement // we'll call it $outer_query $obj_array = array(); // going to save objects in this $ids = array(18,19,20); // just example id numbers $query = "SELECT field1, field2 FROM table1 WHERE id=?"; $stmt = $db->prepare($query); foreach ($ids as $id) { $stmt->bind_param("i", $id); $stmt->execute(); $stmt->bind_result($var1, $var2); $stmt->store_result(); // I think I need this for data_seek while ($q1 = $outer_query->fetch_object()) { while ($stmt->fetch()) { if ($q1->field1 == $var1) { // looking for a match $obj = new stdClass(); $obj->var1 = $var1; $obj->var2 = $var2; $obj_array[] = $obj; $stmt->data_seek(0); // reset for outer loop break; // found match, so leave inner } } } } The problem I seem to be experiencing is that the values are not getting bound in the variables as I would expect after the first time I use fetch in the inner loop. Specifically, in one example I ran with 3 ids for the foreach, the first id was processed correctly, the second was processed incorrectly (matches were not found in the inner loop even though they existed), and then the third was processed correctly. Is there something wrong with the prepared statment function calls in the sequence I am doing above, or is this an invalid way to use the results of the prepared statement? Thanks.

  • PHP ingore case sensitivity when comparing array values

    - by dan.codes
    I have to modify some code in a application I am working on that is using the array_diff($array1,$array2) method. The problem I am having is it is case sensitive and I need to have it return the correct value if the array values match even if the case is different. I don't want to change the case to lowercase because I need the value returned to keep its case. I'm a little confused as the best method to do this.

  • reduce bandwidth streaming mp3s php...

    - by Scarface
    Hey guys, quick question for any experts out there. I am allowing users to upload and post mp3s so other users can listen to/stream. I was wondering if anyone had any tips for reducing bandwidth, or any tips or methods for streaming mp3s. I currently just reference the location of the file with my flash mp3 player after the file has been uploaded. I would ask about images as well, but I am pretty sure they can be compressed using gzip or mod_deflate

  • [PHP] using the magic __set() method with 2D arrays

    - by Spoonface
    If I have the following registry class: Class registry { private $_vars; public function __construct() { $this->_vars = array(); } public function __set($key, $val) { $this->_vars[$key] = $val; } public function __get($key) { if (isset($this->_vars[$key])) return $this->_vars[$key]; } public function printAll() { print "<pre>".print_r($this->_vars,true)."</pre>"; } } $reg = new registry(); $reg->arr = array(1,2,3); $reg->arr = array_merge($reg->arr,array(4)); $reg->printAll(); Would there be an easier way to push a new item onto the 'arr' array? This code: 'array[] = item' doesn't work with the magic set method, and I couldn't find any useful info with google. Thanks for your time!

  • Split string into smaller part with constrain [PHP RegEx HTML]

    - by Sadi
    Hello, I need to split long string into a array with following constrains: Each part will have a limited number of character (e.g. not more than 8000 character) Each part can contain multiple sentences (delimited by . [full stop]) but never a partial sentences. Except if the last part of the string (as last part may not have any full stop. The string may contain HTML tags. But the tag can not be divided as ( to ). That means HTML tag should be intact. But starting tag and ending tag can be stay on different segment/chunk. I think regular expression with preg_split can do it. Would please help me with the proper RegEx. Thank you Sadi
