Count the duplicate value in the array list using php

Count the duplicate value in the array list using php - php

I have an array in which I need to count duplicate values.
Here's the original array...
array(
[0] => 23.07.2014
[1] => 23.07.2014
[2] => 23.07.2014
[3] => 22.07.2014
[4] => 22.07.2014
[5] => 21.07.2014
[6] => 21.07.2014
[7] => 21.07.2014
[8] => 20.07.2014
[9] => 20.07.2014
[10] => 19.07.2014
[11] => 19.07.2014
[12] => 18.07.2014
[13] => 18.07.2014
[14] => 18.07.2014
[15] => 17.07.2014
[16] => 17.07.2014
[17] => 17.07.2014
[18] => 16.07.2014
[19] => 15.07.2014
[20] => 14.07.2014
[21] => 13.07.2014
[22] => 13.07.2014
[23] => 12.07.2014
[24] => 12.07.2014
[25] => 11.07.2014
[26] => 11.07.2014
[27] => 10.07.2014
[28] => 09.07.2014
[29] => 09.07.2014
[30] => 08.07.2014
)
and I want to get a count of every value in the array, for example:
23.07.2014 Count=3
24.07.2014 Count=2
25 07.2014 Count=1
29.07.2014 Count=1
28.07.2014 Count=1

Use this :
print_r(array_count_values($array));

Try this...
$vals = array_count_values($array);
$key=array_keys($vals);
$value=array_values($vals);
$count=count($vals);
for($i=0;$i<$count;$i++)
{
echo $key[$i]."=>".$value[$i]."</br>";
}

Something likethis should work: (not tested)
unset($tempArr);
foreach ($arr as $elem => $content) {
if(isset($tempArr[$content]) $tempArr[$content]++;
else $tempArr[$content] = 0;
}
echo '<pre>'.print($tempArr).'</pre>';

You can try this by diffrent count of existing array count and unique array count...
`$duplicates = count($currentArray)-count(array_unique($currentArray));
echo $duplicates;

PHP Array not returning the correct columns

I have a query the returns columns from the INFORMATION_SCHEMA.
I then create an array, use the array in a foreach loop to create another array.
The issue I have is the final array starts at a position 0, producing column SeqID0 but the first column is SeqID1:
Array ( [0] => SeqID0 [1] => SeqID1 [2] => SeqID2 [3] => SeqID3 [4] => SeqID4 [5] => SeqID5 [6] => SeqID6 [7] => SeqID7 [8] => SeqID8 [9] => SeqID9 [10] => SeqID10 [11] => SeqID11 [12] => SeqID12 [13] => SeqID13 [14] => SeqID14 [15] => SeqID15 [16] => SeqID16 [17] => SeqID17 [18] => SeqID18 [19] => SeqID19 [20] => SeqID20 [21] => SeqID21 [22] => SeqID22 [23] => SeqID23 [24] => SeqID24 [25] => SeqID25 [26] => SeqID26 [27] => SeqID27 [28] => SeqID28 [29] => SeqID29 [30] => SeqID30 [31] => SeqID31 [32] => SeqID32 [33] => SeqID33 [34] => SeqID34 [35] => SeqID35 [36] => SeqID36 [37] => SeqID37 [38] => SeqID38 [39] => SeqID39 [40] => SeqID40 [41] => SeqID41 [42] => SeqID42 [43] => SeqID43 [44] => SeqID44 [45] => SeqID45 [46] => SeqID46 )
How can I make the array start at SeqID1.
This is my code;
$strSQLCol = "SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME= 'NXLHR_Active' AND COLUMN_NAME LIKE 'SeqID%'";
$rsCol = mysqli_query($link,$strSQLCol);
$SeqList = array();
do {
$SeqList[] = $row;
} while($row = $rsCol->fetch_assoc());
$SeqIDArray = array();
foreach($SeqList as $key => $value) {
$SeqIDArray[] = 'SeqID' . $key;
}
Many thanks in advance for your time.

Here your improved code. Notice I have added a conditional in foreach:
foreach($SeqList as $key => $value) {
if (1 > $key) { continue; }
$SeqIDArray[] = 'SeqID' . $key;
}

Sort Images by Number in PHP

I am trying to get my image slides to display in order by number with the following:
$image=array();
$img_folder = $params->get('path');
mt_srand((double)microtime()*1000);
if(is_dir($img_folder)){
krsort($file);
$imgs = dir($img_folder);
while ($file = $imgs->read()) {
if ((eregi("gif", $file) || eregi("jpg", $file) || eregi("png", $file)))
$image[] = "$file";
} closedir($imgs->handle);
print_r($image);
return $image;
}
However, the array works but the order is off:
Array ( [0] => Slide1.png [1] => Slide10.png [2] => Slide11.png [3] => Slide12.png [4] => Slide13.png [5] => Slide14.png [6] => Slide15.png [7] => Slide16.png [8] => Slide17.png [9] => Slide18.png [10] => Slide19.png [11] => Slide2.png [12] => Slide20.png [13] => Slide21.png [14] => Slide22.png [15] => Slide23.png [16] => Slide24.png [17] => Slide25.png [18] => Slide26.png [19] => Slide27.png [20] => Slide28.png [21] => Slide29.png [22] => Slide3.png [23] => Slide30.png [24] => Slide31.png [25] => Slide4.png [26] => Slide5.png [27] => Slide6.png [28] => Slide7.png [29] => Slide8.png [30] => Slide9.png )
If I put natsort($image); after $image[] = "$file"; the order is correct but the array is off:
Array ( [0] => Slide1.png [11] => Slide2.png [22] => Slide3.png [25] => Slide4.png [26] => Slide5.png [27] => Slide6.png [28] => Slide7.png [29] => Slide8.png [30] => Slide9.png [1] => Slide10.png [2] => Slide11.png [3] => Slide12.png [4] => Slide13.png [5] => Slide14.png [6] => Slide15.png [7] => Slide16.png [8] => Slide17.png [9] => Slide18.png [10] => Slide19.png [12] => Slide20.png [13] => Slide21.png [14] => Slide22.png [15] => Slide23.png [16] => Slide24.png [17] => Slide25.png [18] => Slide26.png [19] => Slide27.png [20] => Slide28.png [21] => Slide29.png [23] => Slide30.png [24] => Slide31.png )
I need them to order Slide1 - Slide30, not like listed above. I could change the names from numeric (Slide1) to alphabetic (SlideA) but would like to keep this naming convention. Is there a way to do this without changing the image names?
This image slide is a "how to" slide show.

NatSort is what you are looking for.
just use natsort($image);
You can reference it at:
http://php.net/manual/es/function.natsort.php

I didn't know about natsort(), this should do it too though..
$imgs = scandir(dir($img_folder));
$sorted = array();
foreach($imgs as $img){
$index = intval(trim($img, "Slide.png"));
$sorted[$index] = $img;
}
ksort($sorted);
$sorted = array_values($sorted);

You can use natsort() function
natsort
e.g.
$array1 = array("img12.png", "img10.png", "img2.png", "img1.png");
natsort($array);
print_r($array);
This way you will get out put is :
Array ( [3] => img1.png [2] => img2.png [1] => img10.png [0] => img12.png )
You can also use natcasesort($image). It sort an array using a case insensitive "natural order" algorithm.

This did the trick!!!
Just after
$image[] = "$file";
I added
sort($image, SORT_NATURAL | SORT_FLAG_CASE);
This correctly orders the images in the array and the order:
Array ( [0] => Slide1.png [1] => Slide2.png [2] => Slide3.png [3] => Slide4.png [4] => Slide5.png [5] => Slide6.png [6] => Slide7.png [7] => Slide8.png [8] => Slide9.png [9] => Slide10.png [10] => Slide11.png [11] => Slide12.png [12] => Slide13.png [13] => Slide14.png [14] => Slide15.png [15] => Slide16.png [16] => Slide17.png [17] => Slide18.png [18] => Slide19.png [19] => Slide20.png [20] => Slide21.png [21] => Slide22.png [22] => Slide23.png [23] => Slide24.png [24] => Slide25.png [25] => Slide26.png [26] => Slide27.png [27] => Slide28.png [28] => Slide29.png [29] => Slide30.png [30] => Slide31.png )

Get common values from a single multidimensional array in php

I have a array called $array which is multidimensional array. It consits of keys like brandname, productsubcategory (Keys are not static they can be anything and even number of keys are not fixed). I want all the common values from the array
Current array:
$array = array
(
[brandname] => Array
(
[0] => Array
(
[0] => sony_brandname
[1] => touch screen_type
[3] => 2.8_size
[4] => gsm + gsm_sim_support
[5] => 2_primary_camera
[6] => 64 mb_internal_memory
[7] => 32_expandable_memory
[8] => 1200_standard_battery_type
[9] => 3_size
[10] => 1000_standard_battery_type
[11] => touch and type_type
)
)
[productsubcategory] => Array
(
[1] => Array
(
[0] => karbonn_brandname
[1] => touch and type_type
[2] => micromax_brandname
[3] => 2.8_size
[4] => gsm_sim_support
[5] => 3.15_primary_camera
[6] => 52 mb_internal_memory
[7] => 8_expandable_memory
[8] => 1000_standard_battery_type
[9] => nokia_brandname
[10] => symbian s40_os_clean
[11] => 5_primary_camera
[12] => 128 mb_ram
[13] => 256 mb_internal_memory
[14] => 32_expandable_memory
[15] => 1110_standard_battery_type
[16] => gsm + gsm_sim_support
[17] => 2_primary_camera
[18] => 32 mb_ram
[19] => 10 mb_internal_memory
[20] => no_expandable_memory
[21] => 1020_standard_battery_type
[22] => 680 mhz_processor
[23] => 64 mb_ram
[24] => 128 mb_internal_memory
[25] => 860_standard_battery_type
[26] => blackberry_brandname
[27] => 2.45_size
[28] => 1 ghz_processor
)
)
);
Desired array :
$array = array
(
[0] => sony_brandname
[1] => touch and type_type
[2] => 2.8_size
[8] => 1000_standard_battery_type
[16] => gsm + gsm_sim_support
[17] => 2_primary_camera
)

Use array_intersect():
$result = array_intersect($array["brandname"][0], $array["productsubcategory"][1]);
print_r($result);

How can I insert an associative array into sql?

This is my array:
[abominado] => Array
(
[0] => r├⌐probo
[1] => r├⌐probo
[2] => abominado
[3] => banido
[4] => condenado
[5] => detestado
[6] => odiado
[7] => precito
[8] => renegado
[9] => repudiado
)
[abominar] => Array
(
[0] => repelir
[1] => repelir
[2] => abominar
[3] => afastar
[4] => afugentar
[5] => arredar
[6] => desalojar
[7] => desviar
[8] => detestar
[9] => empuxar
[10] => escorra├ºar
[11] => espinafrar
[12] => execrar
[13] => exercer
[14] => expulsar
[15] => grimpar
[16] => impugnar
[17] => odiar
[18] => rebater
[19] => recha├ºar
[20] => recusar
[21] => rejeitar
[22] => relegar
[23] => repudiar
)
how can I insert it into sql ?

foreach ($abominado as $key=>$str)
{
$string .= "$key:$str\n";
}
mysql_query("INSERT INTO strings VALUES ('".mysql_real_escape_string($string)."')");

You can use serialize to cast it to string and unserialize when you get it

First, these arrays happen to be sequential.
Second, in a SQL table, any column can be used as a search criteria, so just insert the data directly and set up an index on any searchable column.

Count the duplicate value in the array list using php - php

Use this : print_r(array_count_values($array));

Try this... $vals = array_count_values($array); $key=array_keys($vals); $value=array_values($vals); $count=count($vals); for($i=0;$i<$count;$i++) { echo $key[$i]."=>".$value[$i]."</br>"; }

Something likethis should work: (not tested) unset($tempArr); foreach ($arr as $elem => $content) { if(isset($tempArr[$content]) $tempArr[$content]++; else $tempArr[$content] = 0; } echo '<pre>'.print($tempArr).'</pre>';

You can try this by diffrent count of existing array count and unique array count... `$duplicates = count($currentArray)-count(array_unique($currentArray)); echo $duplicates;
