PHP - Php Array From Files
Hello,
I'd like to make an array preferably multidimensional from files what are in subdirectory. Here is a code what I wrote but I doesn't work well becouse I wanted to load that string into javascript array..but it didnt work becouse it had some special characters.. Code: [Select] $dir = opendir('f'); if($dir) { $result = ""; while (($file = readdir($dir)) !== false ) { if(strpbrk($file, 'mp3')) { $result = $result ."{ Track name: \"$file\", location: \"f/$file\" },<br/>"; } } echo $result; } Similar TutorialsHello I have a simple question about file handling... Is it possible to list all files in directories / subdirectories, and then read ALL files in those dirs, and put the content of their file into an array? Like this: array: [SomePath/test.php] = "All In this php file is being read by a new smart function!"; [SomePath/Weird/hello.txt = "Hello world. This is me and im just trying to get some help!";and so on, until no further files exists in that rootdir. All my attempts went totally crazy and none of them works... therefore i need to ask you for help. Do you have any ideas how to do this? If so, how can I be able to do it? Thanks in Advance, pros How would I copy an array of selected files? I know how to list them using a 'for' loop, and how to separate them using a 'foreach' loop, but I am unable to get a checkbox array to copy to a destination folder. Help is appreciated. Hi, I have this php code to display the url of the files and it works fine, it just has a weird order when it is echoed out. Here is the code: Code: [Select] <?php $date = date("Y-m-d"); $picarray = array(); $handle = opendir ('pqimages/'.$date.'/'); while (false !== ($file = readdir($handle))) { if($file != "." && $file != "..") { $picarray[] = "http://randomaydesigns.com/pqimages/".$date."/".$file.""; } } $json_array = json_encode($picarray); echo $json_array; ?>There are three files in the folder and they are 33,34,35.jpg it displays them like 33,35,34.jpg Any Recommendations? Thanks, GEORGE Here is my current code to display files from the end to beginning : Code: [Select] <?php function func() { $date = date("Y-m-d"); $picarray = array(); $userarray = array(); $handle = opendir ('pqimages/'.$date.'/'); while (false !==($file = readdir($handle))) { if($file != "." && $file != "..") { $picarray[] = "http://blah.com/pqimages/".$date."/".$file.""; $userarray[]= "pqimages/".$date."/".$file.""; } } sort($picarray); sort($userarray); closedir($handle); $json_array = json_encode($picarray); echo $json_array; } func(); ?> How could I change this from end to beginning for ($picarray)? Cheers, George Hello, I'm making a imagegallery and when someone upload a new image that image has to appear as first picture of the gallery. I'm using an array for the files, but how can I sort the files on date, newest first.? <?php $n = 0; $pathToThumbs = "images/tekeningen/"; $dir = opendir( $pathToThumbs ); while (false !== ($fname = readdir($dir))){ // strip the . and .. entries out if ($fname != '.' && $fname != '..'){ $tekeningen[$n] = $fname; } echo $tekeningen[$n]."<br />"; $n = $n +1; } closedir( $dir ); ?> I found solutions with ksort and filemtime, but I don't understand them and/or they didn't work for me. So far I have managed to create an upload process which uploads a picture, updates the database on file location and then tries to upload the db a 2nd time to update the Thumbnails file location (i tried updating the thumbnails location in one go and for some reason this causes failure) But the main problem is that it doesn't upload some files Here is my upload.php <?php include 'dbconnect.php'; $statusMsg = ''; $Title = $conn -> real_escape_string($_POST['Title']) ; $BodyText = $conn -> real_escape_string($_POST['ThreadBody']) ; // File upload path $targetDir = "upload/"; $fileName = basename($_FILES["file"]["name"]); $targetFilePath = $targetDir . $fileName; $fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION); $Thumbnail = "upload/Thumbnails/'$fileName'"; if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){ // Allow certain file formats $allowTypes = array('jpg','png','jpeg','gif','pdf', "webm", "mp4"); if(in_array($fileType, $allowTypes)){ // Upload file to server if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){ // Insert image file name into database $insert = $conn->query("INSERT into Threads (Title, ThreadBody, filename) VALUES ('$Title', '$BodyText', '$fileName')"); if($insert){ $statusMsg = "The file ".$fileName. " has been uploaded successfully."; $targetFilePathArg = escapeshellarg($targetFilePath); $output=null; $retval=null; //exec("convert $targetFilePathArg -resize 300x200 ./upload/Thumbnails/'$fileName'", $output, $retval); exec("convert $targetFilePathArg -resize 200x200 $Thumbnail", $output, $retval); echo "REturned with status $retval and output:\n" ; if ($retval == null) { echo "Retval is null\n" ; echo "Thumbnail equals $Thumbnail\n" ; } }else{ $statusMsg = "File upload failed, please try again."; } }else{ $statusMsg = "Sorry, there was an error uploading your file."; } }else{ $statusMsg = 'Sorry, only JPG, JPEG, PNG, GIF, mp4, webm & PDF files are allowed to upload.'; } }else{ $statusMsg = 'Please select a file to upload.'; } //Update SQL db by setting the thumbnail column to equal $Thumbnail $update = $conn->query("update Threads set thumbnail = '$Thumbnail' where filename = '$fileName'"); if($update){ $statusMsg = "Updated the thumbnail to sql correctly."; echo $statusMsg ; } else { echo "\n Failed to update Thumbnail. Thumbnail equals $Thumbnail" ; } // Display status message echo $statusMsg; ?> And this does work on most files however it is not working on a 9.9mb png file which is named "test.png" I tested on another 3.3 mb gif file and that failed too? For some reason it returns the following Updated the thumbnail to sql correctly.Updated the thumbnail to sql correctly. Whereas on the files it works on it returns REturned with status 0 and output: Retval is null Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif' Failed to update Thumbnail. Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif'The file rainbow-trh-stache.gif has been uploaded successfully. Any idea on why this is? I am using WPSQT plugin in my blog site .I code some files in PHP also.how to add that files in plugin files.
hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped.

This is form: <form action="dodaj_klan.php" method="post" > <p> <label>Naziv klana:</label> <input name="naziv" type="text" size="20%" /> <label>Web Sajt:</label> <input name="website" type="text" size="20%" /> <label>E-Mail:</label> <input name="email" type="text" size="20%" /> <br /><br /> <label>Igraci klana(5):</label> <input name="lider" type="radio" value="1" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="2" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="3" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="4" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="5" /> <input name="igraci[]" type="text" size="20%" /> <label><i>(obelezi lidera klana)</i></label> <br /><br /> <input class="button" type="submit" name="submit" value="Dodaj" /> </p> </form> Now i wonna save this igraci[] array in mysql, i tried like this but it doesn't work: $igraci = $_POST['igraci']; $query = "INSERT INTO klanovi (naziv, website, email, igraci) VALUES ('{$naziv}', '{$website}', '{$email}', '{$igraci}')"; $result = mysql_query($query, $connection); How can i do this? Thanks.. I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription. I am trying to pull the shortdescription from the listings table with the query $shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' "))); The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462 The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them. Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data? Using curl_multi, I have loaded up 3 url's and then printed the array. 1) How can I also set a timestamp on output to let me know when each url was run? 2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code <?php function multiRequest($data, $options = array()) { // array of curl handles $curly = array(); // data to be returned $result = array(); // multi handle $mh = curl_multi_init(); // loop through $data and create curl handles // then add them to the multi-handle foreach ($data as $id => $d) { $curly[$id] = curl_init(); $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d; curl_setopt($curly[$id], CURLOPT_URL, $url); curl_setopt($curly[$id], CURLOPT_HEADER, 0); curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1); // post? if (is_array($d)) { if (!empty($d['post'])) { curl_setopt($curly[$id], CURLOPT_POST, 1); curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']); } } // extra options? if (!empty($options)) { curl_setopt_array($curly[$id], $options); } curl_multi_add_handle($mh, $curly[$id]); } // execute the handles $running = null; do { curl_multi_exec($mh, $running); } while($running > 0); // get content and remove handles foreach($curly as $id => $c) { $result[$id] = curl_multi_getcontent($c); curl_multi_remove_handle($mh, $c); } // all done curl_multi_close($mh); return $result; } $data = array(array(),array()); $data[0]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json'; $data[1]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json'; $data[2]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json'; $r = multiRequest($data); print_r($r); ?> Output Array ( => Pearl Jam [1] => Black Eyed Peas [2] => Nirvana ) Preferred Output 01:00:01 Pearl Jam 01:00:02 Black Eyed Peas 01:00:03 Nirvana Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. I have mysql select query shown below retrieving data from a database:
$sql = " SELECT student, sum( test_score ) as score FROM test INNER JOIN level ON test.level_id = level.level_id GROUP BY student" $result = $mysqli->query($sql, MYSQLI_STORE_RESULT); if($result) { while ($row = $result->fetch_array(MYSQLI_ASSOC)) { var_dump($row); } }On inspection of the retrieved array with var_dump(), i have these result below: array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : <?php $myStr = ( "00ffff", "00cccc", "009999", "007777", "004444", "001111", "01ffff", "01cccc", "019999" ); ?> & turn it into 3 separated arrays like : <?php $myNewArrs = [ Array1 ( 3 ), Array2 ( 3 ), Array3 ( 3 ), ]; ?> which REALLY looks like : <?php $myNewArrs = [ Array ( "00ffff", "00cccc", "009999" ), Array ( "007777", "004444", "001111" ), Array ( "01ffff", "01cccc", "019999" ), ]; ?>
? Thank you & have a great afternoon!
Edited May 27 by AquariaXI I need a help in the following : I have an admin page from where the admin attaches an gif image.This attached image should be shown to the user as a scrolling image. The code for the scrolling image is done through javascript. So my actual problem is getting the name of the attached gif image to the javascript array which is used for scrolling horizontally. This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 I have a for loop which extracts info from a MySQL table, chooses something then needs to push each bit into an array: for($i = 0 ; $i < $query_report_rows ; ++$i) { $row= mysql_fetch_row($query_names); if($row[6] == 0) { $sName = $row[1]; } elseif($row[6] == 1) { $sName = $row[2]; } $name = "$row[0], $sName"; $print = nl2br($row[7]); } What i need is a multidimensional array to hold $name and $print: $name_print = array( array('name'=>$name 'print'=>$print ) ) How do i array push into such an array from the above for loop? (multi-dimensional array are a very weak point at the moment, so any pointers here would be very much appreciated) Hi, A piece of software I'm using an array is made that looks like the following: Code: [Select] [["Select","Vehicle",0.142933,[0.15,0.4,0.05,0.01]]] How would I be best parsing it so: Square brackets currently showing an array becomes an array within PHP Text strings surrounded by "quotations" lose the quotation mark when stored in the PHP array Numbers remain as values in the PHP array The arrays can become quite large, so which would be the best way to go about it?
