$db_string = "|1||3||1||5||1||3||8||1||10||2|2||13||2||15|";
$array = array_filter(explode("|", $db_string));
if(in_array("1", $array)){
echo"<li>
Honeymoon Packages
</li>";
}
RESULT is Coming
* Honeymoon Packages
* Honeymoon Packages
* Honeymoon Packages
* Honeymoon Packages
because in array 1 is there 4 times, how do I group this in array and print result one time without duplicate?
I do prefer splitting with a regex, so no empty values will ever occur.
$db_string = "|1||3||1||5||1||3||8||1||10||2|2||13||2||15|";
$array = preg_split('/\|/', $db_string, 0, PREG_SPLIT_NO_EMPTY);
Now the array has an element for each number in the listed order. With the help of array map we use the empty $data array and build a key for unique element. So we know how many entries are there per item.
$data = [];
array_map(function($e) use (&$data) { isset($data[$e]) ? $data[$e]++ : $data[$e] = 1; }, $array);
Array
(
[1] => 4
[3] => 2
[5] => 1
[8] => 1
[10] => 1
[2] => 3
[13] => 1
[15] => 1
)
You can use the keys to have each item uniquely.
print_r(array_unique(array_keys($data)));
Array
(
[0] => 1
[1] => 3
[2] => 5
[3] => 8
[4] => 10
[5] => 2
[6] => 13
[7] => 15
)

I have a table with locations stored in the format:
30°28'25"
68°28'43"
In the process of converting from DMS to DEC, I'd need a function to convert the string 68°28'43" (no spaces among values-symbols) into
$deg = 68
$min = 28
$sec = 43
Or something similar. Thanks
Simply use preg_match_all :)
the following regex simply captures every digits (\d) which are contains exactly 2 numbers ({2}) and group them (the braces around the expression)
<?php
$value = "68°28'43\"";
preg_match_all('/(\d{2})/', $value, $matches);
print_r($matches);
$matches would be an array with the captured results (the digits)
Array
(
[0] => Array
(
[0] => 68
[1] => 28
[2] => 43
)
[1] => Array
(
[0] => 68
[1] => 28
[2] => 43
)
)
And then you can simply assign it to your variables with the list() function as follow:
list($deg, $min, $sec) = $matches[0];
echo $deg; // 68
echo $min; // 28
echo $sec; // 43

I need to write a product basket for my website, but I can't remove an index from array. I wrote an array index below:
Array
(
[0] => Array
(
[urun_id] => 174
[urun_adi] => ANT-5527N - Dual Polarity Parabolic Dish Anten 4.8-6.1Ghz 27Dbi
[urun_fiyati] => 672
[urun_fiyati_kur] => TL
[urun_adeti] => 1
)
[1] => Array
(
[urun_id] => 149
[urun_adi] => Cloud Router Switch 16x SFP+(10G ) 1Gbit Eth
[urun_fiyati] => 1683
[urun_fiyati_kur] => TL
[urun_adeti] => 1
)
[2] => Array
(
[urun_id] => 175
[urun_adi] => ANT-5531N - Dual Polarity Parabolic Dish Anten 4.8-6.1Ghz 31Dbi
[urun_fiyati] => 694
[urun_fiyati_kur] => TL
[urun_adeti] => 1
)
)
You can use unset for this:
unset($array[2]); removes the element with index 2

I have an array, I can print it with
print_r($show_arr);
it gives me this output(html source)
Array
(
[0] => Marvel's Daredevil.S01E01 - Into the Ring.mp4
[1] => Marvel's Daredevil.S01E02 - Cut Man.mp4
[2] => Marvel's Daredevil.S02E05 - Kinbaku.mp4
[3] => Marvel's Daredevil.S02E06 - Regrets Only.mp4
)
how would I go about getting the array to look like this?
Array
(
Season[1] => Array
(
Array(
episode => "01 - Into the Ring",
file => "Marvel's Daredevil.S01E01 - Into the Ring.mp4",
)
Array(
episode => "02 - Cut Man",
file => "Marvel's Daredevil.S01E02 - Cut Man.mp4",
)
)
Season[2] => Array
(
Array(
episode => "05 - Kinbaku",
file => "Marvel's Daredevil.S02E05 - Kinbaku.mp4",
)
Array(
episode => "06 - Regrets Only",
file => "Marvel's Daredevil.S02E06 - Regrets Only.mp4",
)
)
I was bored. Just loop your array and use preg_match() to build the array using the matched groups:
foreach($show_arr as $val) {
preg_match('/[^.]+\.S([\d]+)E([0-9]+[^.]+).*/', $val, $m);
$result['Season'][(int)$m[1]][(int)$m[2]] = array('episode' => $m[2],
'file' => $m[0]);
}
[^.]+ is 1 or more NOT dot . characters
\.S([\d]+) is a dot . then S followed by 1 or more digits (capture as group 1)
E([0-9]+[^.]+) is E followed by 1 or more digits followed by 1 or more NOT dot . characters (capture as group 2)
Additionally, this indexes the subarray by the episode. If you don't want that, remove the [(int)$m[2]] and just use [].

I have a array with 2500 elements..I want simple algorithm to get the following.
If the input is 1 , then it should return 1st 50 elements.
If the input is 2 it should return 51 to 100th element.
if input is 3 it should return 101 to 150th element.
I am too much confused with this algorithm and my mind is not giving any idea,Some one please help me.
Note: i am coding my own pagination for 2500 url..And i need just algorithm idea..not coding
<?php
$ar = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30];
function return_frame($arr, $multiplier, $frame_size=50, $preserve_keys = false) {
return array_slice($arr, ($multiplier - 1)*$frame_size, $frame_size, $preserve_keys);
}
print_r(return_frame($ar, 2, 15, false));
?>
Array

Take a look at: http://php.net/manual/en/function.array-slice.php
i think you just can add position and range on your sql code like this :
"select * from blabla order by post desc limit $position,$range"
You have indexes from 0 to 2499 right.
you want a $count of 50.
Let me show you the thinking process.
so if you get 1 as a $paramter you want $start to be 0 and $end to be 49.
lets see:
1-$parameter is $start right. and 50-$paramter is $end . ok
for 2 you want $start to be 50 and $end to be 99;
the above does not work here. lets play with the $count
$parameter*count; is almost $end.. we have to play for the 0 indexing. so:
$end will be $parameter*$count-1. we can see that this is true for 1,2 and also 3 as $parameters.
$start will be ($parameter-1)*$count . just quickly in the head that gives 0,50,100. just what we want.
as #cars10 suggested we do not need the $end. with array_slice($arr,($parameter-1)*$count,$count);
