I have this array:
Array (
[0] => 1
[1] => 0
[2] => 0.32593699614063
[3] => -0.010875407736967
[4] => 0.32593699614063
[5] => 0.325936996140630.32593699614063
[6] => 0.1135301278
[7] => -0.028758634562
[8] => 0.044068247856859
[9] => -0.028758634562
[10] => 0
[11] => -0.01759558330449
[12] => 0
[13] => 0
[14] => 0
[15] => 0.05005732991382
[16] => 0.17093532486612
[17] => 0.098872325264
[18] => 0.346220929
[19] => 0.098872325264
[20] => 0.38405017865388
[21] => 0.098872325264
[22] => 0.64744282045057
[23] => 0.098872325264
[24] => 1
[25] => 0
)
I need to convert it to the following string:
1 0, 0.32593699614063 -0.010875407736967, 0.32593699614063 0.32593699614063, etc.
In other words, there should be a comma after every two elements.
Can you suggest the php code? Currently I have string without commas after every two elements.
Code:
$od = array_flatten($MultiDimensional)
$result = implode(" ",$od);
Output:
1 0 0.32593699614063 -0.010875407736967 0.32593699614063 -0.028758634562 0.1135301278 -0.028758634562 0.044068247856859
You can use array_chunk with implode
$arr = [1,2,3,4,5,6,7,8,9,10];
$res= '';
foreach(array_chunk($arr, 2) as $key => $value){
$res .= ($key < count(array_chunk($arr, 2))-1) ? (implode(' ',$value).",") : implode(' ',$value);
}
Live Demo
You can combine array_chunk, array_map and implode :
$od = array(1, 0, 0.32593699614063, -0.010875407736967, 0.32593699614063, -0.028758634562, 0.1135301278, -0.028758634562, 0.044068247856859);
echo implode(',' , // each pair is separated by a comma
array_map(function($pair){return implode(' ', $pair);}, // each element in pair separated by a space
array_chunk($od, 2) // cut original array in blocks of 2 items
)
);

I want all arrays data in one array not all arrays in one array only the data of all arrays in one array without any other array in php. I have tried to do too many things but still don't work for me.
I also tried
json_encode
with
preg_match
But still don't work for me.
Here is my code
function fetchHashtags($getData){
$body = $getData;
$hashtag_set = [];
$array = explode('#', $body);
foreach ($array as $key => $row) {
$hashtag = [];
if (!empty($row)) {
$hashtag = explode(' ', $row);
$hashtag_set[] = '#' . $hashtag[0];
}
}
print_r($hashtag_set);
}
Output
Array

[0] => #Residência
[1] => #architecture
[2] => #casanaserra
[3] => #mountainhouse
[4] => #interiores

)
And one more thing i also want to remove some data that don't look like hashtags.
for example:
Array
(
[0] => #Residência
[1] => architecture // This should be removed
[2] => #casanaserra
[3] => mountainhouse // This also should be removed
[4] => #interiores
)
As you can see from my code you can use array_merge for merge arrays then use array_filter for filter value without # or other rules you need:
$array = [['1', '#2', '3', '#4'], ['5', '#6']];
$flatArray = array_merge(...$array);
$filteredArray = array_filter($flatArray, function($a) {
if (str_contains($a, '#')) {
return $a;
}
});
print_r($filteredArray);
Result:
Array (
[1] => #2
[3] => #4
[5] => #6 )
Reference:
array_merge
array_filter
str_contains
After seeing your code and the context of the situation I changed things:
Instead of use explode i used preg_split for split \n and space;
Delete array_map because you don't need it.
$array = ["
My name is Faraz shaikh i am a php developer and this my #instagram profile.Check out my #merge and my #packages with new #hashtags
#chinese #art #colors #home #harmory #peace #handmade #paintings #etsy
", "
My name is Hunain shaikh i am a php developer and this my #Facebook profile.Check out my #Berge and my #Hackages with new #tags
#english #Kite #colours #me #memory #pee #made #paints #etsafsy
"];
function fetchHashtags($getData) { // This Functions takes out the hashtags from the string and put it in to arrays.
$body = $getData;
$hashtag_set = [];
$array = preg_split('/[\s]+/', $body);
$mapArray = array_map(function($a) {
return str_replace(' ', '', $a);
}, $array);
$filteredArray = array_filter($mapArray, function($a) {
if (str_contains($a, '#')) {
return $a;
}
});
return $filteredArray;
}
$recentNumberOfPosts = 1;
$zeroPost = 0; //Get Post from 0 to recentNumberOfPosts | NOTE: default = 4
$finalArr = [];
while ($zeroPost <= $recentNumberOfPosts) {
// fetchHashtags($hashtagRecent['data'][$zeroPost]['caption']);
$finalArr[] = fetchHashtags($array[$zeroPost]);
$zeroPost++;
}
print_r(array_merge(...$finalArr));
Fiddle
Using cURL:
$url = $some_site;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
where the '$output' variable contains the following 7 columns (# of rows will vary):
1,a,6045,6168,6731,6847,522800
2,b,7847,8124,7645,7716,614400
3,c,7288,7633,7150,7442,801800
4,d,5546,5791,5460,5581,554200
5,e,4579,4679,4359,4572,557400
etc ...
As you can see, in the 4th column, the numbers are:
6168
8124
7633
5791
4679
And the highest number is: 8124
I am trying to figure out how to parse the '$output' variable so I can evaluate all the numbers in the 4th column to determine the high.
I have tried:
$csv = array_map('str_getcsv', $output);
echo max($csv[4]);
But nothing is returned
If you output your $csv value you will see that it is array with structure like:
...
[2] => Array
(
[0] => 3
[1] => c
[2] => 7288
[3] => 7633
[4] => 7150
[5] => 7442
[6] => 801800
)
[3] => Array
(
[0] => 4
[1] => d
[2] => 5546
[3] => 5791
[4] => 5460
[5] => 5581
[6] => 554200
)
[4] => Array
(
[0] => 5
[1] => e
[2] => 4579
[3] => 4679
[4] => 4359
[5] => 4572
[6] => 557400
)
....
So your $csv[4] is not a list of values from column 4. It's the 5th element of your array. So you need to go further, either with a simple foreach:
$max = 0;
foreach ($csv as $row) {
// use index `3` because numeration starts with `0`
if ($max < $row[3]) {
$max = $row[3];
}
}
Or with array_column (since php5.5):
// take all values witn index `3` and find max
echo max(array_column($csv, 3));
In both cases it is 8124
It's because str_getcsv not following standards, and from output You have a "broken array"... I suppose that it may look like this:
Array
(
[0] => 1
[1] => a
[2] => 6045
[3] => 6168
[4] => 6731
[5] => 6847
[6] => 522800
2
[7] => b
[8] => 7847
[9] => 8124
[10] => 7645
[11] => 7716
[12] => 614400
3
[13] => c
[14] => 7288
[15] => 7633
[16] => 7150
[17] => 7442
[18] => 801800
4
[19] => d
[20] => 5546
[21] => 5791
[22] => 5460

[25] => e
[26] => 4579
[27] => 4679
[28] => 4359
[29] => 4572
[30] => 557400
)

You can do it like this:
<?php
// $csv is just a string ... output from Your curl will be same I think
$csv = <<<EOT

EOT;

I am trying to figure a way to get this to work. But I have a hard time thinking out the logics.
I have this array:
Array
(
[0] => Array
(
[0] => news
[1] => {section}
[2] => {slug}
[3] => {*}
)
[1] => Array
(
[0] => {id}
[1] => {*}
)
[2] => Array
(
[0] => {date}
[1] => 25-07-1982
[2] => {section}
[3] => {slug}
[4] => {*}
)
)
That I need to convert to this result:
0 news/{id}/{date}
1 news/{id}/25-07-1982
2 news/{id}/{section}
3 news/{id}/{slug}
4 news/{id}/{*}
5 news/{*}/{date}
6 news/{*}/25-07-1982
7 news/{*}/{section}
8 news/{*}/{slug}
9 news/{*}/{*}
10 {section}/{id}/{date}
11 {section}/{id}/25-07-1982
12 {section}/{id}/{section}
13 {section}/{id}/{slug}
14 {section}/{id}/{*}
15 {section}/{*}/{date}
16 {section}/{*}/25-07-1982
17 {section}/{*}/{section}
18 {section}/{*}/{slug}
19 {section}/{*}/{*}
20 {slug}/{id}/{date}
21 {slug}/{id}/25-07-1982
22 {slug}/{id}/{section}
23 {slug}/{id}/{slug}
24 {slug}/{id}/{*}
25 {slug}/{*}/{date}
26 {slug}/{*}/25-07-1982
27 {slug}/{*}/{section}
28 {slug}/{*}/{slug}
29 {slug}/{*}/{*}
30 {*}/{id}/{date}
31 {*}/{id}/25-07-1982
32 {*}/{id}/{section}
33 {*}/{id}/{slug}
34 {*}/{id}/{*}
35 {*}/{*}/{date}
36 {*}/{*}/25-07-1982
37 {*}/{*}/{section}
38 {*}/{*}/{slug}
39 {*}/{*}/{*}
The input array could contain more than three keys, so the solution I'm looking for should be dynamic. And the result should have the same order as the result shown above.
Does someone know how to do this in a efficient way? Can someone give me a push in the right direction? Thanks a lot! :)
Sth like this
foreach ($array[0] as $val0 )
foreach ($array[1] as $val1 )
foreach ($array[2] as $val2 )
$newArray[] = "$val0/$val1/$val2";
EDIT: for variable array length
function recursive($array , $length = 0){
$retval =array();
if($length < count($array) -1){
foreach ($array[$length] as $val0 )
foreach (recursive($array, $length+1) as $val1)
$retval[] = "$val0/$val1";
}
else
{
foreach ($array[$length] as $val0 )
$retval[] = "$val0";
}
return $retval;
}
print_r(recursive($array));
Just because I like writing functions that mis/manage PHP arrays, I put this together, mainly because I was pretty sure you could avoid recursion — because the structure itself isn't recursive. (My head seems to think that is a rule, I'm sure someone somewhere can prove it wrong).
foreach ( array_reverse($array) as $sub ) {
if ( isset($rem) ) {
$ret = array();
foreach ( $sub as $itm ) {
foreach ( $rem as $val ) { $ret[] = "$itm/$val"; }
}
$rem = $ret;
}
else {
$rem = $sub;
}
}
The output found in $rem is as follows:
Array (
[0] => news/{id}/{date}
[1] => news/{id}/25-07-1982
[2] => news/{id}/{section}
[3] => news/{id}/{slug}
[4] => news/{id}/{*}
[5] => news/{*}/{date}
[6] => news/{*}/25-07-1982
[7] => news/{*}/{section}
[8] => news/{*}/{slug}
[9] => news/{*}/{*}
[10] => {section}/{id}/{date}
[11] => {section}/{id}/25-07-1982
[12] => {section}/{id}/{section}
[13] => {section}/{id}/{slug}
[14] => {section}/{id}/{*}
[15] => {section}/{*}/{date}
[16] => {section}/{*}/25-07-1982
[17] => {section}/{*}/{section}
[18] => {section}/{*}/{slug}
[19] => {section}/{*}/{*}
[20] => {slug}/{id}/{date}
[21] => {slug}/{id}/25-07-1982
[22] => {slug}/{id}/{section}
[23] => {slug}/{id}/{slug}
[24] => {slug}/{id}/{*}
[25] => {slug}/{*}/{date}
[26] => {slug}/{*}/25-07-1982
[27] => {slug}/{*}/{section}
[28] => {slug}/{*}/{slug}
[29] => {slug}/{*}/{*}
[30] => {*}/{id}/{date}
[31] => {*}/{id}/25-07-1982
[32] => {*}/{id}/{section}
[33] => {*}/{id}/{slug}
[34] => {*}/{id}/{*}
[35] => {*}/{*}/{date}
[36] => {*}/{*}/25-07-1982
[37] => {*}/{*}/{section}
[38] => {*}/{*}/{slug}
[39] => {*}/{*}/{*}
)
Also, for those that like their arrays multidimensional, this might come in handy (although I'd hate to think what the overheads are for such a code golfed version). Just to be clear, this second example doesn't create the string list as requested by the OP, but a hierarchical array structure instead.
foreach ( array_reverse($array) as $sub ) {
$rem = isset($rem)
? array_combine($sub, array_fill(0, count($sub), $rem))
: $sub
;
}
This generates (again in $rem):
Array (
[news] => Array (
[{id}] => Array (
[0] => {date}
[1] => 25-07-1982
[2] => {section}
[3] => {slug}
[4] => {*}
)
[{*}] => Array (
[0] => {date}
[1] => 25-07-1982
[2] => {section}
[3] => {slug}
[4] => {*}
)
)
[{section}] => Array (
[{id}] => Array (
[0] => {date}
[1] => 25-07-1982
[2] => {section}
[3] => {slug}
[4] => {*}
)
... and so on
Now if only PHP had a join_recursive that included keys.
(it would be almost pointless, save for helping with the above).
I have two arrays built from different directories that contain file names stripped of extensions. I want to find the ones that don't make a pair thus I merged the array to obtain the array below. How can I find the only non duplicate item in an array?

[17] => dbbackup_2014.09.03_08_41_36
[18] => dbbackup_2014.09.03_08_43_38
)
Note: it is [9]
$a = array_flip(array_filter(array_count_values($a),function($item){
return $item == 1 ? true : false;
}));
print_r($a);
Output
Array

[1] => dbbackup_2014.09.04_04_59_08

Ideone
foreach($array as $data)
{
$values=explode("_",$data);
$output[$values[1]]++;
}
foreach($output as $date=>$number)
{
if($number==1)
echo $date;
}
Output:

and i want to replace 'empty' with 0 without change the array structure and elements position. I stuck how to do..
You can use array_walk_recursive function:
function replace_empty(&$item, $key) {
$item = str_replace('empty', '0', $item);
}
array_walk_recursive($your_array, 'replace_empty');
You could use the array_walk_recursive function, with a callback function that would replace empty by 0.
For example, considering your array is declared this way :
$myArray[0] = array(23, empty, 43, 12);
$myArray[1] = array(empty, empty, 53, 19);
Note : I supposed you made a typo, and your arrays are not containing only a string, but several sub-elements.
You could use this kind of code :
array_walk_recursive($myArray, 'replacer');
var_dump($myArray);
With the following callback functon :
function replacer(& $item, $key) {
if ($item === empty) {
$item = 0;
}
}
Note that :
the first parameter is passed by reference !
which means modifying it will modify the corresponding value in your array
I'm using the === operator for the comparison
And you'd get the following output :
array(
0 =>
array
0 => int 23
1 => int 0
2 => int 43
3 => int 12
1 =>
array
0 => int 0
1 => int 0
2 => int 53
3 => int 19)
I would foreach in both indices (not tested):
foreach($array as $country){
foreach($country as &$field){
if($field[1] == 'empty'){
$field[1] = 0;
}
}
}
(I assume empty is a string)
EDIT:
If this [1990,0.00] is not an array but a string, you could use str_replace instead
foreach($array as $country){
foreach($country as &$field){
$field = str_replace('empty', '0.00', $field);
}
}
}
