I have two array as following
Array
(
[0] => 641
[1] => 622
[2] => 100
[3] => 6431
)
Array
(
[0] => 64.1
[1] => 62.2
[2] => 10
[3] => 643.1
)
How can I make it as following
Array
(
[0] => 641
[1] => 64.1
[2] => 622
[3] => 62.2
[4] => 100
[5] => 10
[6] => 6431
[7] => 643.1
)
It's as simple as
$result=array_merge($array1,$array2);
Note: Your values wont be in the order you presented though. If that is important then you need to loop through your arrays to build a new array accordingly.
Ummm ok here is that version as well
if(count($array1)==count($array2))
{
for($i=0;$i<count($array1);$i++)
{
$result[]=$array1[$i];
$result[]=$array2[$i];
}
}
print_r($result);
Fiddle
Manual
you can use array_merge() function merges one or more arrays into one array.
example:
array_merge(array1,array2,array3...)

So this is how my Array ($dataArray) looks oks like:
Array
(
[0] => Array
(
[0] => Date
[1] => Time
[2] => Duration
[3] => Info
[4] => Client
)
[1] => Array
(
[0] => 2021-12-01
[1] => 10:45:43
[2] => 237
[3] => Some text from
[4] => Client 1
)
[2] => Array
(
[0] => 2021-12-01
[1] => 11:29:13
[2] => 77
[3] => Nothing important
[4] => Client 2
)
[3] => Array
(
[0] => 2021-12-01
[1] => 11:53:03
[2] => 44
[3] => anonymous
[4] => Client 1
)
I need to Loop trough it to search the Client Names, and if i find the matching name in the Element 4 then delete the entire Array.
$ExportKDname = "Client 1"
foreach($dataArray as $key => $sub_array) {
if($sub_array[4] == $ExportKDname) {
unset($dataArray[$key]);
break;
}
}
print_r($dataArray);
But with this code none of the arrays will be deleted. And I just can not find the right way to do it.
The Final array what I need to look like if we find the "Client 1" in the array would be like this:
Array
(
[0] => Array
(
[0] => Date
[1] => Time
[2] => Duration
[3] => Info
[4] => Client
)
[1] => Array
(
[0] => 2021-12-01
[1] => 11:29:13
[2] => 77
[3] => Nothing important
[4] => Client 2
)
In the if condition you are saying "if u match with $sub_arr[4] == $ExportKDname unset it and stop the loop". the machine doing that. when it matched first time it removes and stoping. If u wanna delete all match do not write break; let it continue. So delete or make it comment break; line.
You can array_filter your variable and check if value is in_array.
With PHP 7.4+ syntax it should look like this:
$result = array_filter($dataArray, fn ($innerArray) => !in_array('Client 1', $innerArray));
I have an arbitrary number of arrays all containing the same format of data. There are 2 separate for loops looping through two separate SQL query results and adding them to 2 separate arrays.
Once I have all the information in both arrays, I am walking through them and joining them together to make a longer array.
However, as I am writing this array to a csv file, The information needs to be in order in the array so it writes it in order to the csv file. How can I do this?
Array 1
[1] => Array
(
[0] => 2017-07-21 00:00:00
[1] => Foo
[2] => Bar
[3] => 32.63
[4] => 18.36
[5] => 98.46
)
[2] => Array
(
[0] => 2017-07-21 00:00:00
[1] => Foo
[2] => Bar
[3] => 29.74
[4] => 148.68
[5] => 178.42
)
//etc
Array 2
[1] => Array
(
[0] => RTGH707321222
[1] => THIS
[2] => IS
[3] => TEXT
)
[2] => Array
(
[0] => RTGH707321220
[1] => SOME
[2] => WORDS
[3] => HERE
)
//etc
Joining the arrays together
array_walk($array2, function($values, $key) use (&$array1) {
$array1[$key] = array_merge($array1[$key], $values);
} );
After The array Merge - print_r($array1)
[1] => Array
(
[0] => 2017-07-21 00:00:00
[1] => Foo
[2] => Bar
[3] => 32.63
[4] => 18.36
[5] => 98.46
[6] => RTGH707321222
[7] => THIS
[8] => IS
[9] => TEXT
)
[2] => Array
(
[0] => 2017-07-21 00:00:00
[1] => Foo
[2] => Bar
[3] => 29.74
[4] => 148.68
[5] => 178.42
[6] => RTGH707321220
[7] => SOME
[8] => WORDS
[9] => HERE
)
//etc
So this is working fine. However, I would like to move some of these indexes around so that they are in a different order. I have looked into array_splice() but I am not sure if this is the correct method to use.
What I want it to look like
[1] => Array
(
[0] => 2017-07-21 00:00:00
[1] => RTGH707321222
[2] => TEXT
[3] => THIS
[4] => 18.36
[5] => 98.46
[6] => Foo
[7] => 32.63
[8] => IS
[9] => Bar
)
//etc
As you can see, all the information is still the same. The values have just been moved to different indexes. How can I sort the array so that it looks like the above. Can anyone point me in the right direction? Thanks.
This is a simpler method using array_replace() and an ordering array.
No extra loop, no temporary swapping variables.
Code: (Demo)
$array1=[
1=>['2017-07-21 00:00:00','Foo','Bar',32.63,18.36,98.46],
2=>['2017-07-21 00:00:00','Foo','Bar',29.74,148.68,178.42]
];
$array2=[
1=>['RTGH707321222','THIS','IS','TEXT'],
2=>['RTGH707321220','SOME','WORDS','HERE']
];
$order=[0=>'',6=>'',9=>'',7=>'',4=>'',5=>'',1=>'',3=>'',8=>'',2=>''];
array_walk($array2, function($values, $key) use (&$array1,$order) {
$array1[$key] = array_replace($order,array_merge($array1[$key], $values));
});
var_export($array1);
we can use swap technice here like,
<?php
foreach ($arr as $key => $value) {
$swap = $value[1];
$arr[$key][1] = $value[6];
$arr[$key][6] = $swap;
$swap = $value[9];
$arr[$key][9] = $value[2];
$arr[$key][2] = $swap;
$swap = $value[7];
$arr[$key][7] = $value[3];
$arr[$key][3] = $swap;
}
print_r($arr);
?>
$arr is your array.
This is my array () ...not much English'm using google translator.
I'm printing this array with print_r (). but what I deceo is sort of form this down
Array
(
[0] => Array
(
[0] => 606125999550609
[1] => Patricia
[2] => Michelle
)
[1] => Array
(
[0] => 724417787635260
[1] => Nasshy
[2] => Green
)
[2] => Array
(
[0] => 1121064174618668
[1] => Luisanna
[2] => Rodriguez
)
[3] => Array
(
[0] => 1057585894278115
[1] => Libane
[2] => Heredia
)
)
Basically what I need is to sort this array as follows......
So I do not know how to sort follows in PHP...
Array
(
[0] => 606125999550609
[1] => 724417787635260
[2] => 1121064174618668
[3] => 1057585894278115
[4] => Patricia
[5] => Nasshy
[6] => Luisanna
[7] => Libane
[8] => Michelle
[9] => Green
[10] => Rodriguez
[11] => Heredia
)
This isn't so much "sorting", its' more of a manipulation/restructure. Using a loop to regenerate your array would be the option, but if you can modify the data from where it comes from, then that's always recommended.
$new = array();
array_map(function($obj) use(&$new) {
foreach($obj as $i => $elem) {
$new[$i][] = $elem;
}
}, $array);
In the example above, we're using array_map() to apply our function() {... that runs the loop of each element, applying it to our $new array.
All you need to do is pass your $array in as you see above.
Example/Demo
Given this array:
Array
(
[0] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[1] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[2] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
[3] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
)
The ssm_featured_post_id value corresponds to the value of the array items in the second array.
I want to order the first array items in the same order as the items in the second array
Array
(
[1] => 63
[0] => 70
[3] => 1
[2] => 49
)
so the result after sorting would be
Array
(
[0] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[1] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[2] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
[3] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
)
The simpler way would be to use usort and write a function that uses the second table to compare two values from first table.
You may want to check out array_multisort, particularly the third example given. The idea is that you create arrays based on the "columns" of the multidimensional array, then sort them simultaneously, and put the result back in the original array.
EDIT: For anyone who might come across this post with a similar problem, It was solved by taking konforce's supplied answer and tweaking around a bit with the custom sorting function:
function cmp($a, $b) {
if ($a[5] == $b[5]) {
return ($a[3] < $b[3]) ? -1 :1;
}
return ($a[5] > $b[5]) ? -1 : 1;
}
Notice $a[5] == $b[5] does not return zero. It was changed to check who has the most losses and then sort it in ASC order. I'm sure you can even keep going and add another if-statement in there in-case they have the same losses.
Lastly, all you do is usort($ARRAY, "cmp"); and finito!!!
Original Post
My apologies for coming up with yet another MD Array sorting question but I'm just not getting it. I've searched aplenty
for a solution and although many sites have provided what seemed like a logical answer I still have not been able to figure it out.
My problem is since I'm still learning its been rather difficult for me to grasp the concept of using usort with a custom comparing
function. Atleast, thats what I have seen the most when others have tried to sort MD Arrays.
I'm working on a small project to sharpen up on my php skills. Its a very basic tournament standings script that holds a team's information within an array. I would like to sort the array by most points($array[X][X][5]).
So the array looks something like this:
Array (
[0] => Array (
[0] => Array (
[0] => cooller
[1] => 6
[2] => 6
[3] => 0
[4] => 0
[5] => 18
)
)
[1] => Array (
[0] => Array (
[0] => strenx
[1] => 9
[2] => 5
[3] => 1
[4] => 3
[5] => 18
)
)
[2] => Array (
[0] => Array (
[0] => rapha
[1] => 10
[2] => 8
[3] => 1
[4] => 1
[5] => 25
)
) [3] => Array (
[0] => Array (
[0] => ronald reagan
[1] => 5
[2] => 4
[3] => 0
[4] => 1
[5] => 13
)
)
)
I would like to sort it by most points(cell #5), so it would look like this after sorting:
Array (
[0] => Array (
[0] => Array (
[0] => rapha
[1] => 10
[2] => 8
[3] => 1
[4] => 1
[5] => 25
)
)
[1] => Array (
[0] => Array (
[0] => cooller
[1] => 6
[2] => 6
[3] => 0
[4] => 0
[5] => 18
)
)
[2] => Array (
[0] => Array (
[0] => strenx
[1] => 9
[2] => 5
[3] => 1
[4] => 3
[5] => 18
)
)
[3] => Array (
[0] => Array (
[0] => ronald reagan
[1] => 5
[2] => 4
[3] => 0
[4] => 1
[5] => 13
)
)
)
The player with 25 points would be at the top, followed by 18, 18, and lastly 13. Sorry for my earlier post, was having difficulty wording my question correctly. Thanks in advanced!
I think you want something like this:
usort($standings, function($a, $b) { return $b[0][5] - $a[0][5]; });
Or prior to PHP 5.3:
function cmp($a, $b) { return $b[0][5] - $a[0][5]; }
usort($standings, 'cmp');
When using usort, the $a and $b parameters will be one "layer" into the supplied array. So in your case, an example of $a or $b will be:
[0] => Array (
[0] => cooller
[1] => 6
[2] => 6
[3] => 0
[4] => 0
[5] => 18
)
I'm not sure why you have an extra containing array there, but as you can see, you want to sort based on the [0][5] position.
usort($standings[0][0][5], 'cmp') won't work because the first parameter isn't an array to sort, it's just a single number, the points.
