  • Parsing EXIF's "ExposureTime" using PHP

    - by MarkL
    Re, One photo with exposure being 1/640 has the EXIF field of "ExposureTime" eq. "15625/10000000". I am not sure why some photos display this value in a readable format (e.g., "1/100"), but I need to convert this "15625" back to "1/640". How? :) Thanks.

  • PHP/json My field names are being truncated to 30 characters. Can I stop this?

    - by Biff MaGriff
    Hi Everyone! Ok so I got this piece of vendor software that they said should be run on an apache php server and MySql database. I didn't have either of those so I put it on a PHP IIS server and I converted the code to work on SQL server. ex. mysql_select_db - mssql_select_db (among other things) So I have the following code in a php file $query = "SELECT * FROM TableName WHERE KEY_FIELD = '".$keyField."';"; $result = mssql_query($query); $arr = array(); while ( $obj = mssql_fetch_object($result) ) { $arr[] = $obj; } echo '{"results":'.json_encode($arr).'}'; and my results look something like this (captured with fiddler 2) {"results":[{"KEY_FIELD":"57", "My30characterlongfieldthatiscu":"GoodValue"}]} "My30characterlongfieldthatiscu" should be "My30characterlongfieldthatiscutoff" Kinda weird, no? The vendor claims that the app works perfectly on their end. I'm thinking this is some sort of IIS PHP limit, is there a way around it or can I expand it? I found this solution http://www.php.net/manual/en/ref.mssql.php#74834 but I don't understand it. Thanks!

  • PHP Doctrine 1.2 table names

    - by Ofir
    I'm trying to upgrade my doctrine ORM from 1.1.6 to 1.2.1 but i've enountered a BC issue with table names. Some of my table names have several words (e.g. t_foo_bar for class FooBar) where the t_ prefix is generated automatically with: $manager->setAttribute(Doctrine_Core::ATTR_TBLNAME_FORMAT, 't_%s'); This worked well in previous versions. In 1.2.1 however, it looks like doctrine is looking for t_foobar (instead of t_foo_bar with an underscore). Do you know how to solve this without changing the table names?

  • PHP - Drilling down Data and Looping with Loops

    - by stogdilla
    I'm currently having difficulty finding a way of making my loops work. I have a table of data with 15 minute values. I need the data to pull up in a few different increments $filters=Array('Yrs','Qtr','Day','60','30','15'); I think I have a way of finding out what I need to be able to drill down to but the issue I'm having is after the first loop to cycle through all the Outter most values (ex: the user says they want to display by Hours, each hour should be able to have a "+" that will then add a new div to display the half hour data, then each half hour data have a "+" to display the 15 minute data upon request. Now I can just program the number of outputs for each value (6 different outputs) just in-case... but isn't there a way I can make it do the drill down for each one in a loop? so I only have to code one output once and have it just check if there are any more intervals after it and check for those? I'm sure I'm just overlooking some very simple way of doing this but my brain isn't being clever today. Sorry in advance if this is a simple solution. I guess the best way I could think of it as a reply on a form. How you would check to see if it's a reply of a reply, and then if that reply has any replys...etc for output. Can anyone help or at least point me in the right direction? Or am I stuck coding each possible check? Thanks in advance!

  • PHP readdir() not returning files in alphabetical order

    - by Buggabill
    I am reading through a directory with some pictures and such using a pretty simple implementation of readdir() like the following: if ($handle = opendir($path)) { while (false !== ($szFilename = readdir($handle))) { if ($szFilename[0] !== '.') { if (is_file($path.$szFilename)) { // do stuff } } } } The problem that I am having is that the files are not being read in alphabetical order as the docs for readdir() state: Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem. Another weird thing is that, on the local testing server, the same code works great. This is running on a server using the LAMP stack in both cases. I know that I can build an array and just sort it, but I was wondering if I was missing something in what I was doing. Thanks for any insight!

  • How to add a suffix at the end of a string in PHP

    - by Golem
    I am trying to add a .html suffix at the end of all strings supplied by the user before it is entered into the database. Here's my code so far: strtolower(str_replace(" ", "_", $postTitle)); The above takes the title of the post the user it trying to make, turns it to lower case, replaces all white spaces with underscores and makes it ready to be entered into a database column called post_url. I just need it to do one more thing and that's to add a .html at the end of each post url. What is the function to do this?

  • PHP scope question

    - by Dan
    Hi, I'm trying to look through an array of records (staff members), in this loop, I call a function which returns another array of records (appointments for each staff member). foreach($staffmembers as $staffmember) { $staffmember['appointments'] = get_staffmember_appointments_for_day($staffmember); // print_r($staffmember['appointments'] works fine } This is working OK, however, later on in the script, I need to loop through the records again, this time making use of the appointment arrays, however they are unavailable. foreach ($staffmembers as $staffmember) { //do some other stuff //print_r($staffmember['appointments'] no longer does anything } Normally, I would perform the function from the first loop, within the second, however this loop is already nested within two others, which would cause the same sql query to be run 168 times. Can anyone suggest a workaround? Any advice would be greatly appreciated. Thanks

  • php foreach as variable

    - by user167850
    I'd like to use foreach to loop though an array list and add an element to each array. $tom = array('aa','bb','cc'); $sally = array('xx','yy','zz'); $myArrays = array('tom','sally'); foreach($myArrays as $arrayName) { ${$arrayName}[] = 'newElement'; } Is the use of ${$arrayName}[] the best way to do this? Is there another option rather than using curly braces? It currently works but I'm just wondering if there is a better alternative. Thanks

    - by ntan
    Hi to all, i am trying to setup a multidimensional array but my problem is that i can not get the right order from incoming data. Explain $x[1][11]=11; $x[1]=1; var_dump($x); In the above code i get only x[1].

  • php soapclient returns null but getPreviousResults has proper results

    - by Joseph.Chambers
    I've ran into trouble with SOAP, I've never had this issue before and can't find any information on line that helps me solve it. The following code $wsdl = "path/to/my/wsdl"; $client = new SoapClient($wsdl, array('trace' => true)); //$$textinput is passed in and is a very large string with rows in <item></item> tags $soapInput = new SoapVar($textinput, XSD_ANYXML); $res = $client->dataprofilingservice(array("contents" => $soapInput)); $response = $client->__getLastResponse(); var_dump($res);//outputs null var_dump($response);//provides the proper response as I would expect. I've tried passing params into the SoapClient constructor to define soap version but that didnt' help. I've also tried it with the trace param set to false and not present which as expected made $response null but $res was still null. I've tried the code on both a linux and windows install running Apache. The function definition in the WSDL is (xxxx is for security reasons) <portType name="xxxxServiceSoap"> <operation name="dataprofilingservice"> <input message="tns:dataprofilingserviceSoapIn"/> <output message="tns:dataprofilingserviceSoapOut"/> </operation> </portType> I have it working using the __getLastResponse() but its annoying me it will not work properly. I've put together a small testing script, does anyone see any issues here. //very simplifed dataset that would normally be //read in from a CSV file of about 1mb $soapInput = getSoapInput("asdf,qwer\r\nzzxvc,ewrwe\r\n23424,2113"); $wsdl = "path to wsdl"; try { $client = new SoapClient($wsdl,array('trace' => true,'exceptions' => true)); } catch (SoapFault $fault) { $error = 1; var_dump($fault); } try { $res = $client->dataprofilingservice(array("contents" => $soapInput)); $response = $client->__getLastResponse(); echo htmlentities($client->__getLastRequest()); echo '<hr>'; var_dump($res); echo "<hr>"; echo(htmlentities($response)); } catch (SoapFault $fault) { $error = 1; var_dump($fault); } function getSoapInput($input){ $rows = array(); $userInputs = explode("\r\n", $input); $userInputs = array_filter($userInputs); // $inputTemplate = " <contents>%s</contents>"; $rowTemplate = "<Item>%s</Item>"; // $soapString = ""; foreach ($userInputs as $row) { // sanitize $row = htmlspecialchars(addslashes($row)); $xmlStr = sprintf($rowTemplate, $row); $rows[] = $xmlStr; } $textinput = sprintf($inputTemplate, implode(PHP_EOL, $rows)); $soapInput = new SoapVar($textinput, XSD_ANYXML); return $soapInput; }
