PHP - Get Random From Array And Remove Duplicates
Hi guys!
i got this code: Code: [Select] <? $x = "abcde"; str_split($x); for ($k=0; $k<=119; $k++){ $ax = array($x[0],$x[1],$x[2],$x[3],$x[4]); shuffle($ax); $text = implode("", $ax) . ""; echo $text; echo "<br />"; } ?> if you test it you see that it is working but giving me allot of duplicates results! there is a way to ignore duplicaes while it is runing? thanx. Similar TutorialsHello I have a while loop which outputs countrys from the database (im making a "filter by" function). For example, the loop outputs: Denmark Belgium Holland Brazil Japan Brazil Denmark I want to sort these alphabetically and then remove duplicates... Can somebody explain to me how? I don't know how to get them into an array to do it... Doing an API call and want to remove duplicates so I can display the products by brand. Problem I am having now is when I try to display the brands, I am getting duplicate brands. When I display the brands I am getting Nike, Nike, Reebook. When I just want, Nike, Reebok. My Code Code: [Select] <?php $results = array(); //array from API call $results2 = $results['data']; function multi_unique($array) { foreach ($array as $k=>$na) $new[$k] = serialize($na); $uniq = array_unique($new); foreach($uniq as $k=>$ser) $new1[$k] = unserialize($ser); return ($new1); } $results3 = multi_unique($results2); foreach ($results3 as $var) { echo $var['brand']; ?> <br /> <?php } ?> The array Code: [Select] { "errors": [ ], "warnings": [ ], "data": [ { "url": "http://[...]", "image_url": "[...]", "image_thumb_url": "[...]", "keyword": "Red Running Shoes", "description": "Red Running Shoes - Perfect for long jogs!", "category": "Shoes", "price": "59.99", "price_sale": null, "currency": "USD", "merchant": "", "brand": "Nike", "upc": "0944588778", "isbn": null, "sales": 23 }, { "url": "http://[...]", "image_url": "http://[...]", "image_thumb_url": null, "keyword": "Blue Running Shoes", "description": "Blue Running Shoes - Perfect for long jogs!", "category": "Shoes", "price": "59.99", "price_sale": "49.99", "currency": "USD", "merchant": "", "brand": "Nike", "upc": "0944588779", "isbn": null, "sales": 12 } { "url": "http://[...]", "image_url": "http://[...]", "image_thumb_url": null, "keyword": "Black Running Shoes", "description": "Black Running Shoes - Perfect for long jogs!", "category": "Shoes", "price": "59.99", "price_sale": "49.99", "currency": "USD", "merchant": "", "brand": "Reebok", "upc": "0944554779", "isbn": null, "sales": 12 } ], "coupons": [ ], "countryCode": "US", "page": 1, "limit": 10, "totalRecords": 3 } This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=349563.0 I need a way to generate a random number and insert into a database, and I need the database to not contain any duplicates of that number. I basically need to generate a RMA # (Return Merchandise Authorization Number), so the numbers absolutely CAN NOT be duplicate. I have no ideas how to go about this. Should I generate a random number, search the database and see if there's a duplicate, and if there is re-run the script?

So you can see that Grupo has 4 times the value "500" and Departamento has 4 times that string... How can avoid this and have only one value of each?
Thanks
Hi, got a problem with my arrays, every string gets duplicated 11 times instead of just one time. How to fix this? So Im building this little link scraper. The problem I am having is when it outputs the links that are in the array its got duplicate elements. I'm trying to erase the dupes and only show unique values. I've tryed array_unique() with out success as well as in_array(). Any help would be appreciated! //PAGE WE ARE GETTING LINKS ON $diags = str_get_html(getDiagramLinks($html)); //GET THE DIAGRAM LINKS TO PAGES INTO ARRAY foreach($diags->find('a') as $f) { $diagLinks[] = $f->href; } //iterate through the array for($i=0; $i<sizeof($diagLinks); $i++) { //ignore if blank element if(trim($diagLinks[$i]) !== ' ') { echo $diagLinks[$i]. '<br>'; } } The Output: Code: [Select] /partsearch/model.aspx?diagram_id=110375 /partsearch/model.aspx?diagram_id=110375 /partsearch/model.aspx?diagram_id=110376 /partsearch/model.aspx?diagram_id=110376 /partsearch/model.aspx?diagram_id=110377 /partsearch/model.aspx?diagram_id=110377 /partsearch/model.aspx?diagram_id=110378 /partsearch/model.aspx?diagram_id=110378 /partsearch/model.aspx?diagram_id=110379 /partsearch/model.aspx?diagram_id=110379 /partsearch/model.aspx?diagram_id=110380 /partsearch/model.aspx?diagram_id=110380 Hi All, I've a loop which creates an array as follows: $product_table[] = ['SKU' => $sku, 'Label' => $attribute_name, 'Value' => $term_obj->name ]; I'm then grouping the data by SKU code:
#group the products by SKU
$group_products = array();
foreach ($product_table as $element) :
$group_products[$element['SKU']][] = $element;
endforeach;
Finally, I output the data:
#output the data
foreach ($group_products as $itemName => $rows) :
echo '<tr>';
#echo '<td>', $element['SKU'], '</td>';
$i=0;
foreach ($rows as $row) : $i++;
#echo '<td>'. $row["SKU"]. '</td><td>'. $row["Label"]. '</td><td>'. $row["Value"]. '</td>';
if ($i == 1):
echo '<td>'. $row["SKU"]. '</td><td>'. $row["Value"]. '</td>';
else:
echo '<td>'. $row["Value"]. '</td>';
endif;
#echo '<td>'. $row["Value"]. '</td>';
endforeach;
echo '</tr>';
endforeach;
?>
And looks like: Product code System Pack Quantity XT1CWH System 1 1 x 3m XT2CWH System 2 1 x 3m XT3CWH System 3 1 x 3m
This works perfectly fine. However, some products share the same SKU and therefore it causes an issue, like the below: Product code System Pack Quantity XT1CLWH System 1 8 x 3m System 2 8 x 3m System 3 8 x 3m Is there a way I can avoid this, so if perhaps creates the new row but shows the same SKU code? Many thanks I wish to get only the last part of each array 'g' And then show non duplicated 'g' but in the same order that it was in the original array. Code: [Select] <?php $formarray = array( 'name' => array( 'i1'=> array('a'=>'a1', 'b'=>'b1', 'c'=>'c1', 'd'=>'d1', 'e'=>'e1', 'f'=>'f1', 'g'=>'g1'), 'i2'=> array('a'=>'a2', 'b'=>'b2', 'c'=>'c2', 'd'=>'d2', 'e'=>'e2', 'f'=>'f2', 'g'=>'g2'), 'i3'=> array('a'=>'a3', 'b'=>'b3', 'c'=>'c3', 'd'=>'d3', 'e'=>'e3', 'f'=>'f3', 'g'=>'g3'), 'i4'=> array('a'=>'a4', 'b'=>'b4', 'c'=>'c4', 'd'=>'d4', 'e'=>'e4', 'f'=>'f4', 'g'=>'g4'), ) ); foreach ($formarray as $newarray => $a) { ?><strong><?=$newarray;?></strong><br><? foreach ($a as $key => $k) { ?>"<?=$key;?>", <? foreach ($k as $b) { //if ($k['DBfield'] != "") { ?>"<?=$b;?>", <? //} } ?><br><? } //end of second foreach ?><br><br><br><? } //end of first foreach ?> I am trying to write a dirty script that removes duplicate rows from a multidimensional array. I want to be able to edit the function and spit the duplicates out to a CSV file. Here is my test file: $fullArray = array(array('Jim', 'Jones'), array('Pete', 'Pumpkin'), array('Barak', 'Obama'), array('Jason', 'Newstead'), array('Toby', 'Keith'), array('Jim', 'Jones'), array('Jim', 'Nelson')); echo "<h1>Original</h2>"; for($i=0; $i<count($fullArray); $i++) { echo $fullArray[$i][0] . " " . $fullArray[$i][1] . "<br />"; } echo "<h2>Checked</h2>"; $cleanArray = array(); $cay = array(); $nn=0; $dup=0; // Loop the entire input array foreach ($fullArray as $index => $item) { echo "foreach index:$index<br>"; // Start an internal pointer for ($f=0; $f<count($fullArray); $f++) { echo "for $f "; // if the index is lower or the same as the pointer, skip it to cut down on time if ($f > $index) { // if the rows are the same... if($fullArray[$f][0] == $item[0] && $fullArray[$f][1] == $item[1]) { echo "$item[0] DUP<br>"; // remove it from the array $cay = array_push($cleanArray, array($item[0], $item[1])); array_pop($fullArray[5]); $dup++; } else { // not a duplicate echo " not a dup<br>"; } } else { echo "ON THIS ONE<br>"; } } echo "<br><br>"; } echo"<br>$dup duplicates found<br><br>"; print_r($fullArray); echo "<br /><br>"; // print_r($item); print_r($cleanArray); ?> When I spit out the new fullArray variable, it still has an element from the duplicate record.

I can't for the life of me understand how to perform this so I need some professional help here. I have a large array that contains some garbage every Nth and Nth + 1 element that needs to go away. array_filter doesn't work with keys but anyhow, i wouldn't know how to design the function. My keys are numeric, starting from 0. The keys I want to remove are part of this sequence: 8, 9, 18, 19, 28, 29 ... Can someone help me design a generic function to remove these keys? function filter_keys($array, $n, $offset) {} $new_array = filter_keys($array, 10, 8 ); I would maybe have to run this function twice, once for 8 offset and once for 9 offset. Hello guys, need some help. Let us say i have an array = 2011 ipad 2011 ipad review 2011 ipad price 2011 ipad design 2011 ipad reviews review 2011 ipad 2011 ipad feature I would like to review all the array elements that contain "review"...So the final array should look like 2011 ipad 2011 ipad price 2011 ipad design 2011 ipad feature Thanks So, I am making a system that shows if there are new posts or not. How I have it done is a singular array called "Read" will have all of the IDs of the read posts. It is entered in the database like so: $ID2= $_SESSION['UserID']; $ID2 = mysql_real_escape_string($ID2); $Readornot=mysql_query("SELECT * FROM forum_read WHERE Reader_ID='$ID2'"); $Readornot2=mysql_fetch_array($Readornot); if($ID2==0) { } else { if(empty($Readornot2)) { $Read1= array("Read" => $Get_TopicID); $Read2 = implode('-',$Read1); mysql_query("INSERT INTO forum_read (Reader_ID,`Read`) values ('$ID2','$Read2')") or die(mysql_error()); } else { $cr_topicid=$Readornot2['Read']; if(strpos($cr_topicid,'-')) { $cr_topicid=explode('-',$cr_topicid); if(!in_array($Get_TopicID,$cr_topicid,true)) { $Read0=implode('-',$cr_topicid); $Read1= array("Read" => $Read0, $Get_TopicID); $Read2= implode('-',$Read1); mysql_query("UPDATE forum_read SET`Read`='$Read2' WHERE Reader_ID='$ID2'") or die(mysql_error()); } } else { if($cr_topicid==$Get_TopicID) { } else { $Read1= array("Read" => $cr_topicid, $Get_TopicID); $Read2= implode('-',$Read1); mysql_query("UPDATE forum_read SET`Read`='$Read2' WHERE Reader_ID='$ID2'") or die(mysql_error()); } } } } It all works fine and dandy to the point where if it's in the database an icon will be black and white, and if its not it wont, signifying read or unread. What I need to do, however, is make it so when there is a new post, it takes all of the entries in the database with the topic ID out of the database, and strips the one part. What I thought of at first was to use str_replace to replace "-" . $TopicID . "-" with "-" But of course, that won't work, because the very first entry could be the topic ID, so it would just be $TopicID- and not -$TopicID- in the database. So, how would I go about doing this? Just a quick one, new area for me. I have an array which is looped against another array, if the two values from each ever match then an event occurs, if not then something else. If a match does occur i then want to remove the said value from one of the arrays... is this really all i need to do, seems too simple: unset($saved_dont_use[$j]); Is there a built in function to remove empty array values for example: change Array ( [0] => Bob [1] => [2] => Ryan [3] => Jane ) to Array ( [0] => Bob [1] => Ryan [2] => Jane ) Thanks I dont know how to word this really. what I want to do is Code: [Select] $Var[] = 3; $Var[] = 6; $Var[] = 2; $Var[] = 17; for($i=0; $i!=count($Var); $i++) { echo "#$i: ".$Var[$i]."\n"; } I know I might be able to use rand() but I need it to echo ALL of the variables in the array in a random order, I know if I use count to find out how many variables there are that it would echo them 4 times randomly but might echo the same variable 2 times making it to where it only echos 3 different varables, if I am being confusing please let me know, I just want to get this resolved, thanks! Hi, I have an array filled with values like this: Code: [Select] string(1) "Acer 1" string(2) "Acer 2" string(3) "Dell 1" string(4) "Dell 2" string(5) "Dell 3" string(6) "Dell 4" string(7) "Acer 3" string(8) "Acer 4" Is there a way to successfully remove all array strings that starts with a given value like "Acer"? I tried with this snippet, does not work: Code: [Select] foreach($array as &$value) { if(preg_match("/^Acer/", $value)) { unset($value); } } Any ideas will be appreciated! Hey guys does anyone know how i would go about generating a random word from an array? For example: $words = array("[apple]","[banana]","[kiwi]"); how would i have php choose one of these words and then spit it out? Thanks!!! |
