PHP - Min(array) But Ignoring 0s
I have any array $DF containing numeric variables, I want the minimum value of the array stored in $val but ignoring any zeros i.e. the lowest number that is not 0. Is this possible?
Similar TutorialsHi all, I have another uestion. I am currently working with an XML document that has some comments in it that need to stay however it is messing up my parser that I am working on. How can I get around this issue and make the php parser ignore the comments? here is a snippet of the code I am working on. php Code: [Select] //open XML file containing data for current slide $currentslidefilepath = "slides/xml/"; $currentslidefilepath .= $slides[$currentslide]; $currentSlideXml = simplexml_load_file($currentslidefilepath); XML Quote <!-- there are some comments here --> <Basic> <another>some data</another> </Basic> Hi, I have a database table which is full of books e.g book_title, book_author, book_date etc. Im trying to work out a way to list all the authors without duplicating them, if that makes sense. If I do a simple query and then display the book_author in a loop it will show multiple entries for each author. I just want it to display each author once. Hope that makes sense lol sorry Im a newbie. Anyone know how I can do it ? Thanks in advance, Scott. Greetings! I have a CSV file that looks something like this: Quote ,,,,,,,,sdfsdf sdfsdf,,,,,,,,,,,,,,,,,,,,,,sdfsdfsdf:,,,,,,,,2011-04-27,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,dfgdfg,,fgh,,,,,gfh,,,,,,,,,,,,,,fghfgh,,,,,fghf,, fghfh,, fgh,,,,,,fhfgh,,,, Code: [Select] <?php $handle = fopen("csv.csv", "r"); while (($data = fgetcsv($handle, 5000, ",")) !== FALSE) { echo "<pre>"; print_r($data); echo "<pre>"; } ?> Now this prints everything, could someone please provide me with an example of how I can ignore the "empty fields"? Thanks in advance! I have a php script. I defined a variable outside of a function, but i cannot echo the variable inside the function. When I execute this: <?PHP $testvar = "test worked!"; testfunction(); function testfunction(){ echo $testvar; } ?> Nothing happens. what am i doing wrong. I did this on my local host. Apache running on Windows Vista Ultimate 32 bit Edition. Thanks in advance. I have a dynamic menu (jglidemenu) installed on my site. It works fine on my HTML pages but on my PHP pages the font formatting from the menu's style sheet isn't working and I haven't been able to figure out why. Here's a page where the menu is working correctly: http://www.greenbayeasthighschool.com and here's a page where the formatting fails: http://www.greenbayeasthighschool.com/staff_by_lastname.php This is my first attempt at creating a page with PHP. Is it not possible to use CSS formatting on a page that includes PHP content? Thanks in advance for any help. Basically I have the following code (posted below) foreach($char_xml->characterInfo->characterTab->items->item as $item) { //get the item id $item_id = $item->attributes()->id; //get the xml doc for that item from wow armory $url = "http://www.wowarmory.com/item-info.xml?i=" . $item_id; $data = fetchXML($url); //create a SimpleXML object to parse the xml $item_xml = new SimpleXmlElement($data); //print the item's name echo "<li type=square>" . $item_xml->itemInfo->item->attributes()->name . " "; echo "<b>(" . $item_xml->itemInfo->item->attributes()->level . ")</b></br>"; //calculate gear score total $calc=$calc+$item_xml->itemInfo->item->attributes()->level; } echo '</ul>'; //print the total item level echo '<b>Total Additive Item Score (Equipped):</b>' . $calc; echo '<br>'; //calculate the average item level(equipped) $ilvl=$calc/16; echo '<b>Average Item Score (Equipped):</b>' . round($ilvl) . "<br><br>"; It is working relatively well for what I am trying to accomplish. It pulls xml data from wowarmory and uses it to calculate a player's "average item level". The problem I am running in to is if a player is equipped with certain items (that should not be calculated), the average is incorrect. I know atleast the shirt, tabard and off-hand need to be ignored IF equipped. I am trying to find something relative to all 3 items in the xml data and thus tell the script to disregard them. Here is a printed example of the array I am working with (warning its LONG). This is an example of a player that has these 3 extra items.

"[Quality]=>1" which no other items should typically have. The big issue comes with the third odd ball (off hand). This off-hand could be a shield or any weapon with few exceptions depending on the player class. As I continue to try and figure this out, one solution could be to first take the previous two "[Quality]=>1" items out of the equation IF they exist, then ONLY IF there are 17 items remaining subtract the value of block/iteration 17 before calulating as usual. If 16 items, then just run $calc is it currently is. How would I accomplish this? I do not mind displaying the item's name, in fact I would prefer to keep the item list as it currently I just need to not include the said items in the item level average. I know this is probably relatively straight forward to accomplish and that I am a noob, but would be grateful of your assistance. Thanks. I’m trying to work out how I can use php gd to take an image, in this case it’s a rectangle that has text in the middle and the rest is transparent, so it’s a png with just text in the centre.
I have another image which is a texture. Its also a rectangle of the same size. I have managed to merge the two together so the texture on top of the text image but it covers the entire image rather than just the text in the middle.
what I need it to do it apply the texture to the text in the image and ignore the surrounding transparent pixels.
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.

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? How can i save array from inputs, witch is $igraci and it have 5 values, to mysql base, i tryed but in mysql it shows Array. 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 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. 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 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. 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 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 So I'm querying my database to add the results (mapID's) into a PHP array. The MySQL query I used in the below code would usually return 10 values (only 10 mapID's in the database) Code: [Select] while($data = mysql_fetch_array(mysql_query("SELECT mapID FROM maps"))){ $sqlsearchdata[] = $data['mapID']; } Instead the page takes ages to load then gives this error: Quote Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 16 bytes) It says the error begins on the first line of the above code. I'm assuming this is not the right way to add the value from the MySQL array into a normal PHP array. Can anyone help me? I'm creating a quick survey app for my son's cub scout pack's end-of-year surveys. There are two sets of questions: those where they want the responses to be completely anonymous and those questions where we need to know who filled out the response (people volunteering for positions, etc) I'm storing the responses in the db as two separate arrays, $anon and $nonAnon $anon[0] will be an array containing all the questions: $anon[0][0] = Survey question # 1 $anon[0][1] = Survey question #2, etc. The responses will be stored as arrays and placed in $anon as the 2nd element: $anon[1][0][0] = first response, answer to the first question $anon[1][0][1] = first resopnse, answer to the 2nd question $anon[1][1][0] = 2nd response, answer to the 1st question Etc. The pack leadership is concerned that no one would be able to reconstruct which anon response belonged to whom by matching up the order of the anon answers with the non-anon answers. Therefore I'd like to shuffle at least the anon responses. The long answer would be to build a temp array using the elements in $anon[1] and then shuffle that array and then reassign it to $anon[1]. Is there a way to use shuffle directly on $anon[1] without having to build a temporary array, shuffling it, then replacing the elements of $anon[1]? |
