PHP - Handling Errors With Simplexml_load_file
I have an application that loads several xml files, and then outputs some of the data from the file. The problem is that every once in a while, the service that provides the xml file does maintenance (or has an error in the file), and my application gives a "Fatal error: Call to a member function children() on a non-object in..."
I would like to handle the error differently, by displaying "unavailable" instead of the error. I know that this is usually not the appropriate way of handling errors, because there is a reason for a fatal error.
Any ideas on how to appropriately handle this error?
// Node 217 (GGB)
$xml = simplexml_load_file("http://services.my511.org/traffic/API_KEY_REMOVED_FOR_EXAMPLE");
foreach($xml->children() as $traveltime)
{
$ggb = "$traveltime->currentTravelTime";
}
echo "GGB:" , $ggb , " Minutes"; Similar TutorialsWhats the best way to handle database errors. I been using ob_start() stuff to run the code and if a database connection error occurs an variable $error turns to 1 and it displays the error code instead of the normal page that should be displayed when no errors occur. It works but I want to know if there is any better way to manage a db connection error while running a script. Also, how do you manage a problem when like 3 queries are ran to setup a new user account and the last one fails because the db connection drops or something, how would you go about handling a 2/3 query successful? I'm really stuck on how to manage errors if a db connection fails after the first connection is successful. This doesn't work. Based off what I have seen online, it is suppose to. Basically, this is what I tried, and the quote is what was returned. I have no idea how to get this to work. It should have been pretty standard based off of the PHP documentation. The Xpath idea I got from someone else. Either way if I try to use find element by id or tag name it still returns an empty array, no matter what. Any advice on what I am doing wrong is appreciated. It doesn't matter what URL I try, none of them seem to work. Code: [Select] <?php $school_data = file_get_contents('http://www.infotechnologist.biz'); $doc = new DOMDocument(); $doc->validateOnParse = true; $doc->loadHTML($school_data); $xpath = new DOMXPath($doc); $tags = $xpath->query('div'); echo '<pre>'; print_r($tags); echo '</pre>'; ?> Quote DOMNodeList Object ( ) I am writing an API for clients to use to integrate with an server API I have written and it will be used in a variety of different environments and used by people with varying coding styles (hopefully), I was just wondering how I should handle errors? I was going to throw an exception, but what if people don't use a try / catch ? Should I return false to allow them to handle an error? private function _request($uri) { if ( ini_get('allow_url_fopen') ) { $this->_response = file_get_contents($uri); return false; } if ( function_exists('curl_init') ) { $ch = curl_init($uri); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $this->_response = curl_exec($ch); curl_close($ch); return false; } throw new Exception('Allow URL fopen disabled and cURL disabled'); } Also, any scenarios where the above would fail to return a result (apart from the obvious lol) Thanks, Andy Hi, I've inherited some html/php code (lucky me) and it's been years since i've played with it so I'm quite rusty. Anyway, I have a fairly bog standard login process and wish to simply display some text on the login page if the login detail is invalid and possibly log the error to a log file too. here's the index.php file...the login stuff is at the bottom Code: [Select] <?php $dir = dirname(__FILE__); require_once "$dir/ot/ot.php"; ot::include_view('header', array('account' => null)) ?> <html> <head> <title>Welcome to ....</title> </head> <body style="font-size: 14pt; font-family=verdana;"> <div><img src="OTLogo1.bmp"/><h1> Welcome to ...</h1> </div> <?php if (!empty($account)): ?> <div style="border-bottom: 1px dotted #AAA; padding-bottom: 2px; margin-bottom: 10px;"> <div style="float: left"> <?php $mtime = (int)@file_get_contents(otDB_DIR."/updated"); $date = date("d/m/Y", $mtime); $time = date("G:i", $mtime); if ($mtime > 0) { echo "Last Updated $date at $time"; } ?> </div> <div style="float: right">Welcome, <?php echo $account->email;?> - <a href="?page=home">Home</a> - <?php ot::include_view('logout_link')?></div> <div style="clear: both"></div> </div> <?php if (ot::is_admin()) { ot::include_view('admin_page'); } else { ot::include_view('user_page'); } ?> <?php else: ?> <p>Please login below.</p> <?php ot::include_view('login_form')?> <?php endif; ?> </body> </html> here's login_form.php Code: [Select] <form action='<?php echo $_SERVER['REQUEST_URI']?>' method='post' > <fieldset> <legend>Login</legend> <p>Email:<br/><input type='text' name='email' /></p> <p>Password:<br/><input type='password' name='pwd' /></p> <!-- <p><input type='submit' name='do_login' value='Login' /> <input type='submit' name='do_reset_password' value='Reset Password' /></p> --> <p><input type='submit' name='do_login' value='Login'/> </p> </fieldset> </form> and here's the function do_login (contained in ot.php..a php function file) Code: [Select] public static function do_login(&$err="") { $adb = ot::db('account'); $e = self::post('email'); $p = self::post('pwd', '', false); if (self::post('do_login') && $e && $p) { $ao = self::account_from('email', $e); if ($ao) { if (self::validate_login($e, $p, $ao)) { $_SESSION['id'] = $ao->id; return $ao; } } $err = "Invalid email or password"; return false; } } I'm unclear if the do_login fails as to how that ($err) is fed back to the web pages. Any assistance would be greatly appreciated. My first stab at connecting to an API with php. The API takes a url and returns an xml file. When I try this: <?php $apicall = "https://www.graphicmail.com/api.aspx?Username=dyates@salemharvest.org&Password=x&Function=get_newsletters&SID=0"; $xml = simplexml_load_file($apicall); print_r($xml); ?> My local testing server responds with: Warning: simplexml_load_file() [function.simplexml-load-file]: Unable to find the wrapper "https" - did you forget to enable it when you configured PHP? However, in the php configuration file, php.ini, I have: 'allow_url_fopen = On' which is what the manual says is all you need for https use in most functions that take urls. The url that is $apicall works correctly when just pasted into the browser. When I try the php code on the production server I get no warning (they are turned off) and no output. Any ideas? Does the file have to be in the document root? If not, what is the correct syntax to point simplexml_load_file() to a directory on the server that is not the document root? ie what goes between the () this works fine if the .xml file is in my public html root - simplexml_load_file('sample.xml') but when I put the file in a different directory on the server, I can't figure out how to point to it. Help is appreciated. Hi.
I am trying to fetch xml from a betting website feed. The feed is restricted per IP but I have had the server IP, where the site is located, whitelisted and they have confirmed numerous times that the IP has definitely been whitelisted.
If I try to connect using simplexml_load_file to a BBC xml feed it works fine but to the betting feed I get "failed to open stream: HTTP request failed!"
Is there any way of knowing why it is failing or is there anything else that could prevent it from connecting to that specific feed?
many thanks in advance

first off I have to make an empty loc.xml file with permissions in order to write contents, I understand the permission idea. secondly, simplexml_load_file does nothing I get it straight from here http://us2.php.net/manual/en/function.simplexml-load-file.php <?php $request='http://z3950.loc.gov:7090/voyager?version=1.1&operation=searchRetrieve&query=dinosaur&startRecord=2&maximumRecords=5'; //echo $request; $filename = dirname(__FILE__)."/loc.xml"; $raw_xml = file_get_contents($request); //echo $raw_xml; $fp = fopen($filename, "w"); fwrite($fp, $raw_xml); fclose ($fp); // The file test.xml contains an XML document with a root element // and at least an element /[root]/title. if (file_exists($filename)) { $xml = simplexml_load_file($filename); print_r($xml); } else { exit('Failed to open loc.xml.'); } ?> Hi! I'm having trouble accessing data with simpleXML_load_file I have a working script that loads an XML-file and outputs in a proprietary format that I've written, but for some reason I can't get it to work with this second set of XML-files. Loading the file seems to work fine. I load the file into a variable, and can print the contents of the file using echo $xml -> asXML(); However, when I try to access a single node using:
echo $xml->{'SOAP-ENV:Envelope'}->{'SOAP-ENV:Body'}->Order->OrderHeader->OrderNumber->BuyerOrderNumber;
I get the following error:

I have a piece of code that works absolutely fine on my local XAMPP setup but causes a 500 internal server error when I run it on my host (hostgator). $source = "marketplace_feed_v1.xml"; $xml = simplexml_load_file($source,'SimpleXMLElement', LIBXML_NOCDATA); SimpleXML is enabled on hostgator marketplace_feed_v1.xml is located in the same directory as this script I don't understand why this won't work Any help at all is much appreciated. I have a script that uses simplexml_load_file to download weather xml files. It works great except when the file doesn't exist. The server returns an HTML page when the xml file isn't available but the title is something.xml. How can I check to be sure it is an xml file and handle the error when it isn't. I have tried file_exists and access the return code (it's always 200). Can I access the doctype and determine if it HTML or XML? Hello fellow developers, Let me start by saying I'm still a PHP noob so please don't go too hard on me if I my code reflects this noobishness... So I'm trying to build a (very) simple RSS reader using jQuery and PHP. When the user clicks on an option from a dropdown, an AJAX call is made and passes the url selected from the list to a PHP script. The PHP script then loads the appropriate xml file from an 'xmlcache' folder. Everything is working just fine for files named as such: somefilename_1231231231.xml The problem is that I need it to be able to load files which have been urlencoded such as: http%3A%2F%2Ffeeds.feedburner.com%2Fajaxian_1235523548 In case you're wondering, the numbers at the end are a timestamp which will determine if the reader will load a cached copy of the desired xml file (if it's less than an hour old) or if it needs to get a fresh version (this part of the code is not written yet). Here is a look at my script thus far: <?php $url = "./xmlcache/" . urlencode($_REQUEST['url']); //access url from AJAX call echo $url; //outputs -> "./xmlcache/http%3A%2F%2Ffeeds.feedburner.com%2Fajaxian_1235523548.xml", which is the same as the file's name $curTime = time(); $urlParts = explode('_', $url); $urlTime = intval($urlParts[1]); $diff = $curTime - $urlTime; $urlAge = 60 * 60; //60sec * 60min = 3600sec or 1 hour if(file_exists($url)){ if($diff > $urlAge){ //the > will be switched to < to make logical sense once testing is done. $xml = simplexml_load_file($url); //ROOT TAG foreach($xml as $key0 => $value){ echo "$key0: $value"; foreach($value->attributes() as $attributeskey0 => $attributesvalue1){ echo "$attributeskey0: $attributesvalue1"; } echo "<br />"; //1 LEVEL BELOW ROOT TAG foreach($value as $key => $value2){ echo "$key: $value2"; foreach($value2->attributes() as $attributeskey => $attributesvalue2){ echo "$attributeskey = $attributesvalue2"; } echo '<br />'; //2 LEVELS BELOW ROOT TAG foreach($value2 as $key2 => $value3){ echo "$key2: $value3"; foreach($value3->attributes() as $attributeskey2 => $attributesvalue3){ echo "$attributeskey2 = $attributesvalue3"; } echo '<br />'; //3 LEVELS BELOW ROOT TAG foreach($value3 as $key3 => $value4){ echo "$key3: $value4"; foreach($value4->attributes() as $attributeskey3 => $attributesvalue4){ echo "$attributeskey3 = $attributesvalue4"; } echo '<br />'; //4 LEVELS BELOW ROOT TAG foreach($value4 as $key4 => $value5){ echo "$key4: $value5"; foreach($value5->attributes() as $attributeskey4 => $attributesvalue5){ echo "$attributeskey4 = $attributesvalue5"; } echo '<br />'; //5 LEVELS BELOW ROOT TAG foreach($value5 as $key5 => $value6){ echo "$key5: $value6"; foreach($value6->attributes() as $attributeskey5 => $attributesvalue6){ echo "$attributeskey5 = $attributesvalue6"; } echo '<br />'; } } } } echo '<br />'; } echo '<br />'; } }else{ //need to create the XML file from scratch, do a curl function, or read from a text file echo "need a new version"; //@unlink("$url); } }else{ echo "That file does not exist.<br/>"; } ?> The error message I'm getting is this: Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "./xmlcache/http%3A%2F%2Ffeeds.feedburner.com%2Fajaxian_1235523548.xml" in C:\wamp\www\reader\loadfeed.php on line 13 Warning: Invalid argument supplied for foreach() in C:\wamp\www\reader\loadfeed.php on line 16 The second error is obviously thrown because the file doesn't get loaded. I appreciate any help you gurus have to offer, and if you have any suggestions for the best way to load a fresh version that will be handled by the first else statement, I'm all ears. Thanks guys! Hi Guys! I'm new here at PHPFreaks, I have this problem using simplexml_load_file function. I am retrieving an XML from another sub-domain of my project, it's working fine on my local server (win xp, php 5.2.14) but when I try to execute it on our testing server (linux, php 5.2.14) it returns an error something like this.. Warning: simplexml_load_file([url of the script]) [function.simplexml-load-file]: failed to open stream: Connection timed out in [absolute path of the script] on line 3 i have tried cURL and file_get_contents, still get no luck. please note that the XML is validated via w3c.org and works really fine on my local server.. Thanks in advanced! I've been pulling my hair out for the past couple of hours working with simplexml_load_file(). I was attempting to consume a web service generated by asp.net that I've been consuming using CURL and a function to remove the BOM (byte order marker) so that I could load it into simplexml_load_string(). When I switched over to simplexml_load_file() to call the file instead of using CURL and my function, I was getting errors that it could not find the beginning '<' and that the document was empty and so on.. I couldn't find anything about simplexml_load_file() handling BOM characters, so I went for a walk. I came back to my desk and refreshed the page.. and it just started working. I changed nothing! Guess I should be happy that it started working, but I'd sure like to know why it was breaking in the first place, and then why it would suddenly start working without me doing anything. Has anyone else seen anything like this? How do I display the actual errors in IIS 7.5? If I miss a semicolon, I get: "HTTP Error 500.0 - Internal Server Error" absolutely useless. In prior versions, I could see the line and get to the PHP error. How do I display PHP errors? I've added: set_ini('display_errors', '1'); but it doesn't help. Hi, I'm a beginner in PHP OOP and I'm with some doubts about the correct way of handling errors in PHP. Look at this function for example: public function deleteFileFromDisk($fileNameToBeDeleted) { $handle = unlink($fileNameToBeDeleted); if (!$handle) { $result = "(this->deleteFileFromDisk) - Error, " . $fileNameToBeDeleted . " not deleted."; } else { $result = "(this->deleteFileFromDisk) - Success, " . $fileNameToBeDeleted . " deleted."; } return $result; } Is this the correct way of doing it, or I can do better than this? Let me add some details of what I'm achieving... I'm running class methods, and I need to control errors in the process. If any call to the object throw an error I need to catch, stop all the process and send an e-mail with the error. Here are the object interactions: $testar_classe = new geoIpImportCSV('geolitecity', 'http://geolite.maxmind.com/download/geoip/database/GeoLiteCity_CSV/'); $testar_classe->downloadAndSaveFile('./', $testar_classe->obtainDownloadFileName()); $testar_classe->uncompressZipFile($testar_classe->obtainDownloadFileName(), '.'); $testar_classe->deleteLine(1, 'GeoLiteCity-Location.csv'); $testar_classe->deleteLine(1, 'GeoLiteCity-Blocks.csv'); $testar_classe->deleteDataFromTable('tabela1'); $testar_classe->deleteDataFromTable('tabela2'); $testar_classe->insertLinesToDb('GeoLiteCity-Location.csv', 'tabela1'); $testar_classe->insertLinesToDb('GeoLiteCity-Blocks.csv', 'tabela2'); $testar_classe->deleteFileFromDisk($testar_classe->obtainDownloadFileName()); $testar_classe->deleteFileFromDisk('GeoLiteCity-Blocks.csv'); $testar_classe->deleteFileFromDisk('GeoLiteCity-Location.csv'); Which is the best way of handle this? Create a new method to take care of the exceptions? There are any examples on how to do this? Best Regards. Hello there, I'm having a problem displaying money correctly with php. I have a field called "balance" with the type float(10,2), in this field I have a number store as "34.55" which I can go in and look at within phpmyadmin but when I echo this value on the front-end of the site it is displayed as "34.549999237061" Can someone please help? Regards. I have a prepared statement that returns an Article from my database. It then binds the results-set to variables. Most of the fields in the query are "required", so I *assume* that I am guaranteed to always get values back for those fields... Is that presumptuous? Here is a snippet of my code... // Execute query. mysqli_stmt_execute($stmt); // Store results. mysqli_stmt_store_result($stmt); // Check # of Records Returned. if (mysqli_stmt_num_rows($stmt)==1){ // Article was Found. $articleExists = TRUE; // Bind result-set to variables. mysqli_stmt_bind_result($stmt, $articleID, $title, $description, $keywords, $heading, $subHeading, $publishedOn, $author, $body, $referenceListing, $endnoteListing); // Fetch record. mysqli_stmt_fetch($stmt); // Close prepared statement. mysqli_stmt_close($stmt); // ???? Is it sufficient to have code like this... Code: [Select] <title><?php echo $title; ?></title> ...or do I need more error-handling?? Hope that makes sense?! Thanks, Debbie Hi, I have an HTML form created using Dreamweaver and now I need a script to handle the form processing. Basically what I need is for the form data received from the webpage to be organized in an email and then sent to me. I would also like to display a thank you message in the browser so the user knows it was received. I was planning to do this using CGI but a colleague suggested that CGI is old school and nowadays a developer would use PHP for this task. Is PHP the right solution for this project? The examples I have found so far always include the HTML for the form and the script needed to handle it in one file. In my case, I have an HTML form already in place and need it to work with a script to perform the email function. I know I need to set "Action=" on my webpage to point to the PHP script but what would the code look like if no HTML is needed? I hope this makes sense... Thanks for your help! Rob A form needs to get answers of math quiz, returning numbers, up to 2 digits after the point. In all form examples I noticed the usage of: Code: [Select] ...<input type="text" name="name" /... Cant it be a number? floating or integer? why "text" ? Also, can I limit the form to accept numerical input only or would I need to learn Ajax for that? Once I have the answer, I need to compare it to the correct answer. The method I have in mind is to multiply the answer and the correct one by 100 and compare the integer part. Is there a pre-made function that can do the same? |
