PHP - Debug Help Variable Created Vi Curl And Parsed By Regex
I'm a new PHP users needing some help. I've got two code snippets that run a CURL post to a syslog server grabbing specific records that I then parse with regex. Both are similar differing in the specific CURL URL and Regex. One works does not. The failing program seems to fail the regex parse creating a null array. What I've done thus far. Tested the regex on regex101 (works fine, using PCRE). Dumped and echoed the CURL created variable and then rechecked against regex101. ( again all good) Created a static variable in the code of the CURL return string (regex works fine). So the CURL is working, the variable string is working appearing as expected and the regex works. But the variable feels like's it null when passed directly from the CURL to the regex. No error logs, but this is where I'm stuck I don't know what to pick at next. Here's a version of the code. Appreciate any thoughts. <?php
$str = curl_exec($ch); // curl steps ends

I need some help getting my preg_match regex working with a variable input. I'm trying to limit visits to once per day, after you come the first time, you are added to data.txt and will be denied if you come again. The code works, but I need to limit the searches using ^ and $ and I'm having some difficulty. $number will be a number input from an html form ranging from 1-1000+ and I want to make sure that 1,10,100 etc., aren't treated as the same. here is my preg_match, how do I use regular expressions with $number? Code: [Select] preg_match("/$number/", $file, $match) from what I have read, it should be like this, but it doesn't work Code: [Select] preg_match('/^+$' , "/$number/", $file, $match) heres the full code Code: [Select] $filename = "data.txt"; $handle = fopen($filename, "r"); $file = fread($handle,filesize($filename)); if (preg_match("/$number/", $file, $match)) { echo " Sorry, Already visited today"; exit; } else { fclose($file); $file=fopen(data.txt,"a") or exit("Unable to open file!"); fwrite($file, "$number"); fwrite($file, "\n"); fclose($file); echo " Accepted!"; exit; } Thanks Hi I can get this to work can you point me in the right direction curl_setopt( $ch, CURLOPT_URL, "http://website.com/action=%22getcontent%22%20shipid=%22\"$content\"%22%20/%3E%3C/request%3E"); I want to include the variable $content in the url thanks hi guys I just could not find the answer on forum. I have a url like this http://www.example.com/deal.php?id=367 and my question is : how can i use curl function to get the html and the id value which is 367 thanks Hi dear community i want to run a Curl to get the contents of a remote web page into a PHP variable <?php // // The PHP curl module supports the received page to be returned in a variable // if told. // $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,"http://www.myurl.com/"); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); $result=curl_exec ($ch); curl_close ($ch); ?> I declare this variable:($ch) Well - can i work with this variable - eg. to parse this with a parser!? look forward to hear from you $result=curl_exec ($ch); gretings when I send a post variable to another page for processing using cURL and then I echo the variable I am getting extra slashes and periods this is where I set the fields to send. Code: [Select] curl_setopt($ch, CURLOPT_POSTFIELDS,"name='. $name .'&email='. $email .'&serial='. $serialnumber .'"); this is what happens when I echo $serial on the processing page. Code: [Select] \'. SLNM7IV6ZM98YJRXO8D5 .\' it should look like Code: [Select] SLNM7IV6ZM98YJRXO8D5 Hi, I did post a question earlier but have now perhaps narrowed the problem and am still having trouble! I'm still learning PHP by working on a personal project. I'm having an issue accessing an xml file. If I use the following code I get a 'String could not be parsed as XML' error yet if I remove the $postcode variable when defining the $requestaddress variable and extend the url manually it works! Code: [Select] $postcode = $geodata['postcode']; $requestAddress = "http://www.google.com/ig/api?weather=,,," . $postcode; $xml_str = file_get_contents($requestAddress,0); $xml = new SimplexmlElement($xml_str); Any suggestions greatly appreciated. Hi, I'm using an EPP for boring stuff that wont interest you guys anyway. The problem I'm having is the EPP comes with its own API which parses XML for you. The problem with it parsing XML is that the XML that is received comes in a format which has :'s in the keys. Example: Code: [Select] SidnEppResult Object ( [message:SidnEppResult:private] => [status:SidnEppResult:private] => domain_unavailable [code:SidnEppResult:private] => [notifyUser:SidnEppResult:private] => ) Then I want to be able to put this information to use, so I call the constants like this: Code: (php) [Select] <?php echo $object->status:SidnEppResult:private; The problem then is that PHP throws me a little parse error. Any help is appreciated, Chris I have script on my web hosts server built into pages that will be offered to the public, eg: index.php will have some script amongst the html, this script calls other webpages on the net eg: wiki.org Now my question is, when that script runs when somebody accesses that page, will the website eg: wiki.org record the users browser info and ip who called my index page or will it record the webhosts server details as the one making the requests? I have some fairly small text files (2K) which are parsed where certain deliminated fields are replaced with values provided in an associated array. There will typically be less than 5 replaced fields, and I plan on using preg_replace_callback to find and replace them.
I am contemplating caching the files after being parsed (note that they will only be accessed by PHP, and not directly by Apache).
Do you think doing so will provide any significant performance improvement?
If I do go this route, I would like thoughts on how to proceed. I am thinking something like the following:
Append the filename along with the serialized value of the array, and hash it using md5().
Store the parsed file using name "file_".$hash
Get the modification time of the newly created file using filemtime(), and store the value in a new file called "time_".$hash.
bla bla bla
When the next request comes in to parse a file, create the hash again.
If the file exists for the given hash name, and the time file matches filemtime(), use that file, else parse the original file.
Is this a good approach?
I am working on a very simple templating engine and I ran into a problem. Here's the basic template.class.php file <?php class Template { public $template; function load($filepath) { $this->template = file_get_contents($filepath); } function replace($var, $content) { $this->template = str_replace("#$var#", $content, $this->template); } function publish() { eval("?>".$this->template."<?"); } } ?> That is called in whatever model I am using, like this: public function createTemplate() { $templatePath = TEMPLATE_PATH . strtolower(__CLASS__) . ".php"; require_once (APPLICATION_PATH . 'libraries/template.class.php'); $template = new Template; $template->load($templatePath); $template->replace("productid", $this->product_id); $template->replace("price", $this->price); $template->replace("sidebar_message", $this->sidebarmsg); $template->publish(); } My problem is that my template.php ($templatePath) file uses include() to bring in the sidebar, head and footer. Any values that I passed to the template which are in the sidebar, header or footer are not evaluated. They just show their placeholders like #sidebar_message#... Is there another way to do this and publish the template so that they are evaluated properly? I am using this PHP code with a MySQL query. PHP parses the PHP fine, but the MySQL query is not having any effect on the database. Can anyone see an error in my code? I can't. $query = "UPDATE `products` set `id` = '".$_POST['id']."' where `id` = '".$_POST['id']."'"; MOD EDIT: Changed PHP manual link tags to [php] . . . [/php] tags. Hi all I have a question about how to store parsed data into a multidimensional arrays -- I can store items into an array, but multidimensional arrays mystify me a bit. Any help would be greatly appreciated. I'm storing the images in a table, grouped according to their table and their descriptions, so that later when I call the images, I can display them accordingly. I'm using the Simple HTML DOM Parser. So say I have two tables, one with three images, and another with one. I'd like the resulting to array to look like: Code: [Select] Array ( [0] => Array ( [0] => image1.jpg [1] => 1st Variation Description ) [1] => Array ( [0] => image2.jpg [1] => image3.jpg [2] => image4.jpg [3] => 2nd Variation Description ) ) This is what I have so far: Code: [Select] $html = str_get_html($vartables); $varinfo = array(); foreach($html->find('table') as $table){ $varinfo[] = $table->innertext; } print_r($varinfo); Which yields: Code: [Select] Array ( [0] => <tr> <td width=150> Description1 </td> <td><a href="image1.jpg"> <img src="image1" height=100 border=1></a> </td> </tr> [1] => <tr> <td width=150> Description2 </td> <td><a href="image2.jpg"> <img src="image2.jpg" height=200 border=1></a> </td> <td><a href="image3.jpg"> <img src="image3.jpg" height=200 border=1></a> </td> <td><a href="image4.jpg"> <img src="image4.jpg" height=200 border=1></a> </td> </tr> ) I'd like to strip out the html and keep the .jpg's and descriptions together in a multidimensional array...unfortunately my newbness is getting the better of me there, I'm researching but running into a roadblock. Thanks in advance for any help. good day dear community, i am workin on a Curl loop to fetch multiple pages: i have some examples - and a question: Example: If we want to get information from 3 sites with CURL we can do it like so: $list[1] = "http://www.example1.com"; $list[2] = "ftp://example.com"; $list[3] = "http://www.example2.com"; After creating the list of links we should initialize the cURL multi handle and adding the cURL handles. $curlHandle = curl_multi_init(); for ($i = 1;$i <= 3; $i++) $curl[$i] = addHandle($curlHandle,$list[$i]); Now we should execute the cURL multi handle retrive the content from the sub handles that we added to the cURL multi handle. ExecHandle($curlHandle); for ($i = 1;$i <= 3; $i++) { $text[$i] = curl_multi_getcontent ($curl[$i]); echo $text[$i]; } In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle! If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it! Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages: see the some details for this target-server sites - /(I have to create a loop over several hundred sites). * siteone.example/?show_subsite=9009 * siteone.example/?show_subsite=9742 * siteone.example/?show_subsite=9871 .... and so on and so forth Question: How to appy this loop into the array of the curl-multi? <?php /************************************\ * Multi interface in PHP with curl * * Requires PHP 5.0, Apache 2.0 and * * Curl * ************************************* * Writen By Cyborg 19671897 * * Bugfixed by Jeremy Ellman * \***********************************/ $urls = array( "siteone", "sitetwo", "sitethree" ); $mh = curl_multi_init(); foreach ($urls as $i => $url) { $conn[$i]=curl_init($url); curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);//return data as string curl_setopt($conn[$i],CURLOPT_FOLLOWLOCATION,1);//follow redirects curl_setopt($conn[$i],CURLOPT_MAXREDIRS,2);//maximum redirects curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,10);//timeout curl_multi_add_handle ($mh,$conn[$i]); } do { $n=curl_multi_exec($mh,$active); } while ($active); foreach ($urls as $i => $url) { $res[$i]=curl_multi_getcontent($conn[$i]); curl_multi_remove_handle($mh,$conn[$i]); curl_close($conn[$i]); } curl_multi_close($mh); print_r($res); ?> I look forward to your ideas. I need help debugging some homework.I have narrowed the problem down to the switch. when it gets to the switch it is spitting out the default everytime, also in the default the $score in both echo statment is not showing. Its probably something small killing me I just can't see it and dont have enough experience with php yet.

0 downloadsHi all, Well new to the forum. And New to PHP. I have a quick question. I'm trying to figure out what the best pratice would be to get familier with a php installation. More specificly how to discover what php is specificly producing a specific part of the final rendered HTML. I have a MyBB Forum me and my cuzin are setting up and for the life of me i can find the right place to add our own HTML to change a specific Div in the Final page output. here is the link to our URL http://destroyrebuilduntilgodshows.net/forum/ I specificly want to find out where i can edit the contents of the "wrapper_container" Div. I have searched for the source on my local machine. but all i can find is the CSS responsible for the styling and as it turns out the images being held in that div. My end goal is to replace the "advertise here" image with come JS that does our ad managment. So, I guess my question is How would you find it. How would you find the responsible php for that section of the HTML. Thanks All. Cheers I don't know how to debug this. The if is being executed and I want to have the else be executed. How can I find out what $_POST['id'] is? Code: [Select] if (isset($_POST['id']) === false) { echo 'Invalid user id.'; } else { partner_request($_POST['id']); echo "A request has been sent to the user"; } Here is my hierarchy: data -logs folder-debug.log htdocs -index.php include -Contollers,Smarty,Templater,Zend templates Now when I launch index.php from htdocs, I get this un-seeming error: "Fatal error: Uncaught exception 'Zend_Log_Exception' with message '"/var/htdocs/Books/practical_Web2.0/data/logs/debug.log" cannot be opened with mode "a"' in C:\xampp\php\PEAR\Zend\Log\Writer\Stream.php:69 Stack trace: #0 C:\xampp\htdocs\Books\practical_Web2.0\chapter-02\htdocs\index.php(11): Zend_Log_Writer_Stream->__construct('/var/htdocs/Boo...') #1 {main} thrown in C:\xampp\php\PEAR\Zend\Log\Writer\Stream.php on line 69 " I went to the zend folder in xampp, php, pear, zend, log, writer.php dir and I found this: /** * Class Constructor * * @param streamOrUrl Stream or URL to open as a stream * @param mode Mode, only applicable if a URL is given */ public function __construct($streamOrUrl, $mode = 'a') { if (is_resource($streamOrUrl)) { if (get_resource_type($streamOrUrl) != 'stream') { require_once 'Zend/Log/Exception.php'; throw new Zend_Log_Exception('Resource is not a stream'); } if ($mode != 'a') { require_once 'Zend/Log/Exception.php'; throw new Zend_Log_Exception('Mode cannot be changed on existing streams'); } $this->_stream = $streamOrUrl; } else { if (! $this->_stream = @fopen($streamOrUrl, $mode, false)) { require_once 'Zend/Log/Exception.php'; $msg = "\"$streamOrUrl\" cannot be opened with mode \"$mode\""; throw new Zend_Log_Exception($msg); } } $this->_formatter = new Zend_Log_Formatter_Simple(); } line 69 is =>throw new Zend_Log_Exception($msg); What could be wrong?

I have a simple INSERT statement that isn't inserting anything into one of the columns: coin_name I've gone over everything and can't figure out why. All other columns get data. HTML form passes everything fine. Is there a good way to debug this? I've triple checked everything and there are no type-o's that I see. Driving me mad... $query = "INSERT INTO Coin (coin_name, coin_value, coin_condition, year_minted, face_value, purchase_price) VALUES ('$coin_name', '$coin_value', '$coin_condition', '$year_minted', '$face_value', '$purchase_price');"; I am new to PHP and trying to debug some old code. How am I to read the following: $properties = $GLOBALS['Props']; I am guesisin that it is saying: Create a string variable named $porperties and set it equal to the Global variable of 'Props'. But I assume my interpretation is wrong since I get some weird results. I need some advice on how to debug in the middle of other code I want to change a file. This file gives no direct output and contain a load of functions What I want to do is make changes to this file and trace values - how do I do this? - Can I give a popup with a message? - Could I write values to a file? (Can I write to some sort of standard log file? Maybe the error log file?) - Or is it possible to still give output to a web page, even though the code is not part of the code that outputs to the browser? What's the standard practice of debugging as mentioned above? Any help would be really appreciated Thanks! OM |
