I have an array like the example below (from var_dump($tagged);:
array (size=1)
0 =>
array (size=7)
0 => string '#raining' (length=8)
1 => string '#raining' (length=8)
2 => string '#driving' (length=8)
3 => string '#hungrySoon' (length=11)
4 => string '#strangeworld' (length=13)
5 => string '#fruitweekFunky' (length=15)
6 => string '#kevins_rainbow_disco' (length=21)
7 => string '#raining' (length=8)
8 => string '#fruitweekFunky' (length=15)
I am simply after displaying the array as follows (From the most frequent first):
#raining
#fruitweekFunky
#driving ...etc
To achieve exactly what you've asked for (a descending ordered array of the highest occurences to the lowest) step by step:
Count the number of occurences:
$occurences = array_count_values($tagged[0]);
Sort the array (by value, because the number of occurrences is the current array value and the tag is the key - arsort() maintains the original keys):
arsort($occurences);
Get array of the keys for output (because the tags are currently keys):
var_dump(array_keys($occurences));
Fact is, $tagged is an array of arrays. So you need to take its first element.
Try :
$result = array_count_values(array_values($tagged[0]));
var_dump($result);

I am trying to array_merge id’s from one array into another, it’s merging but putting the new values on a new array line:
IDs to be added: $attachment_ids
array (size=2)
0 => string '2620' (length=4)
1 => string '2621' (length=4)
IDs which already exist and will be added to: $existing_data
array (size=1)
0 => string '2589,2561,2432,2422' (length=19)
result of my array_merge:
$merged_data = array_merge($attachment_ids, $existing_data);
is
array (size=3)
0 => string '2620' (length=4)
1 => string '2621' (length=4)
2 => string '2589,2561,2432,2422' (length=19)
My expected result is:
array (size=1)
0 => string '2620,2621,2589,2561,2432,2422'
If you just need the 1 string with all of the values, you could use implode() with the result you have so far...
$merged_data = [ implode(",", $merged_data) ];
Shortly array merge with array_map
$result=array_map(null,$array1,$array2);
array_merge() requires 2 arrays. The existing data is all in a string. With explode, this data can be converted into an array. With implode() a list is created after array_merge().
$attachment_ids = ['2620','2621'];
$existing_data = ['2589,2561,2432,2422'];
$existing_data = explode(',',$existing_data[0]);
$result = [implode(',',array_merge($attachment_ids,$existing_data))];
//$result: array(1) { [0]=> string(29) "2620,2621,2589,2561,2432,2422" }
Update
Alternatively, strings can be chained manually.
$result = [implode(',',$attachment_ids).','.$existing_data[0]];

How to Sort a Multi-dimensional Array by Value
(16 answers)
Closed 3 years ago.
I have an array whith the following content:
array (size=5)
0 =>
array (size=3)
0 => string '1' (length=1)
1 => string 'https://www.facebook.com' (length=24)
2 => string '4' (length=1) // order number
1 =>
array (size=3)
0 => string '1' (length=1)
1 => string 'https://www.twiiter.com' (length=23)
2 => string '7' (length=1) // order number
2 =>
array (size=3)
0 => string '1' (length=1)
1 => string 'https://www.instagram.com' (length=25)
2 => string '9' (length=1) // order number
3 =>
array (size=3)
0 => string '1' (length=1)
1 => string 'https://www.linkedin.com' (length=24)
2 => string '2' (length=1) // order number
4 =>
array (size=3)
0 => string '1' (length=1)
1 => string 'https://www.pinterest.com' (length=25)
2 => string '1' (length=1) // order number
I want to sort this array based on the number in the above code. (where is a written comment).
How can I do this?
So far I have written the following code but I do not know how to make it properly.
$arrMerge = array_merge($facebookURL, $twitterURL, $instagramURL, $linkedinURL, $pinterestURL);
$splitArr = array_chunk($arrMerge, 3);
You can use array_multisort with array_column
array_multisort(array_column($arr, 2), SORT_ASC,$arr)
You can use SORT_ASC OR SORT_DESC as you required
Live DEMO
You can use usort.
usort($data, function($a, $b) {
return $a[2] - $b[2];
});
You might also want to type-cast the result to an integer before-hand as it looks like your data is treated as a string.
usort($data, function($a, $b) {
return (int)$a[2] - (int)$b[2];
});
This is also a possible duplicate of this question.
I'm using preg_match_all() to get matches of the parameters of my url. Problem is matches function send me back an array of array. So it became difficult to explore it with a foreach function (to replace parameters by default parameters for example).
Is there a way to explore straight an array of array and send back the value of the second array, not the first, without passing by the first ?
I put you a simple example of my problem:
$var = "abababa";
preg_match_all("#(a)#", $var, $matches);
$args = array_slice ($matches, 1);
var_dump($args)
arg return me :
array (size=1)
0 =>
array (size=5)
0 => string 'a' (length=1)
1 => string 'a' (length=1)
2 => string 'a' (length=1)
3 => string 'a' (length=1)
And I wish it could return just
array (size=5)
0 => string 'a' (length=1)
1 => string 'a' (length=1)
2 => string 'a' (length=1)
3 => string 'a' (length=1)
Therefore to be able to replace args elements by othes (default elements for example).
Thanks if you can help me.
You can simply do this:
$var = "abababa";
preg_match_all("#(a)#", $var, $matches);
$args = array_slice ($matches[0], 1); // notice we are accessing the first element of $matches
var_dump($args);
This should produce your desired output.
I have a multidimensional array like so:
array (size=4)
0 =>
array (size=2)
'term' => string 'news-article' (length=12)
'count' => int 139
1 =>
array (size=2)
'term' => string 'industry-resource' (length=17)
'count' => int 37
2 =>
array (size=2)
'term' => string 'editorial' (length=9)
'count' => int 33
3 =>
array (size=2)
'term' => string 'bulletin' (length=8)
'count' => int 12
and I'm trying create a function that searches for a term and returns it's neighboring value, count.
My inclination was to use array_search(), however using this returns false, I'm guessin because it's only searching the first layer of the array (0,1,2,3).
I'm not so much looking for an exact answer but a nudge in the right direction. I'm guessing it will require looping through the array, but I do not know how to approach getting the neighboring count value once the term value is located. Any help is appreciated!
You can just loop through the array and access them directly.
$search_term = "news-article";
$count = 0;
foreach($array as $element) {
if($element['term'] == $search_term) {
$count = $element['count'];
break;
}
}
I have a string
$style = "font-color:#000;font-weight:bold;background-color:#fff";
I need only
font-color
font-weight
background-color
I have tried
preg_match_all('/(?<names>[a-z\-]+:)/', $style, $matches);
var_dump($matches);
it gives me following output
array
0 =>
array
0 => string 'font-color:' (length=11)
1 => string 'font-weight:' (length=12)
2 => string 'background-color:' (length=17)
'names' =>
array
0 => string 'font-color:' (length=11)
1 => string 'font-weight:' (length=12)
2 => string 'background-color:' (length=17)
1 =>
array
0 => string 'font-color:' (length=11)
1 => string 'font-weight:' (length=12)
2 => string 'background-color:' (length=17)
There are three problems with this output
1. It is two or three dimensional array, I need one dimensional array.
2. It is repeating the information
3. It is appending ":" at the end of each element.
I need a single array like this
array
0 => 'font-color'
1 => 'font-weight'
2 => 'background-color'
Take out the colon:
$style = "font-color:#000;font-weight:bold;background-color:#fff";
preg_match_all('/(?<names>[a-z\-]+):/', $style, $matches);
var_dump($matches['names']);
Then use $matches['names'], since you named it, so you dont have redundant informations
