Implode a column of values from a two dimensional array [duplicate]
(3 answers)
Closed 7 months ago.
I have the following array:
Array
(
[id] => 1043847
[company] => Array
(
[businesstype] => Array
(
[0] => Array
(
[id] => 6
[name] => Business Service Provider
)
[1] => Array
(
[id] => 8
[name] => Retailer
)
)
)
)
I would like to be able to get the value of company -> businesstype -> name for all the arrays inside businesstype so it would display like this:
Business Type(s): Business Service Provider, Retailer
Right now if I do this:
<?php echo($chamber_member['company']['businesstype']['name']); ?>
Nothing happens, if I do this:
<?php echo($chamber_member['company']['businesstype'][0]['name']); ?>
I get only the one for array [0]. How can I get both values separated by a comma like on the example above? Any help is appreciated, thank you in advance!!
This should work for you:
First get the column into an array with array_column(), then you can simply implode() this array ,e.g.
echo implode(",", array_column($chamber_member["company"]["businesstype"], "name"));
foreach($chamber_member['company']['businesstype'] as $a)
$b[] = $a['name'];
$result = implode(", ", $b);
Take names by array_column and cobine by implode
<?php echo implode(',', array_column($chamber_member['company']['businesstype'], 'name')); ?>
Try to loop into the array position with the 'businesstype' values:
for($i = 0; $i < count($chamber_member['company']['businesstype']); $i++){
echo $chamber_member['company']['businesstype'][$i]['name'] . ', ';
}
I like array_column() but for completeness, just foreach():
foreach($chamber_member['company']['businesstype'] as $array) {
echo $array['name'];
}
Or add to an array and implode().
Another solution using array_map():-
$arr=array
(
'id' => 1043847,
'company' => array
(
'businesstype' => array
(
array
(
'id'=> 6 ,
'name' => 'Business Service Provider'
),
array
(
'id' => 8,
'name' => 'Retailer'
)
)
)
);
echo $names = implode(',',array_map( function($person) { return $person['name']; },$arr['company']['businesstype']));
Use this. best answer for this..
$result=$chamber_member['company']['businesstype'];
$last=end($result);
for($i=0;$i<count($result);$i++)
{
$b[$i] = $result[$i]['name']; echo $b[$i]; if($last!=$result[$i]['name']){ echo ","; }
}

How to implode array indexes?

Closed 3 years ago.
I have an array that I am trying to convert into two strings, one with dates and one with the data values. This is a sample array:
[$output Array below]
Array
(
[2019-03-19] => Array
(
[data_values] => 1566
)
[2019-03-18] => Array
(
[data_values] => 1542
)
[2019-03-17] => Array
(
[data_values] => 786
)
[2019-03-16] => Array
(
[data_values] => 756
)
)
A desired output would be something like:
$dates = '2019-03-19,2019-03-18,2019-03-17,2019-03-16';
$data_values = '1566,1542,786,756';
I've tried this, which will give me the data_values but I can't get the dates, I assume because its the array key?
function implode_r($g, $p) {
return is_array($p) ?
implode($g, array_map(__FUNCTION__, array_fill(0, count($p), $g), $p)) :
$p;
}
$data_values = implode_r(',', $output);
echo $data_values;
You can just use array_keys and array_column:
$dates = implode(',', array_keys($output));
$data_values = implode(',', array_column($output, 'data_values'));
Demo on 3v4l.org
This will give you the answer you expect:
<?php
// Build strings based on array
function implode_r($output) {
$dates = $data_values = "";
if(is_array($output)){
$dates=implode(',',array_keys($output));
$data_values=implode(',',array_column($output, 'data_values'));
}
return compact('dates', 'data_values');
}
// Example usage
$output = [
"2019-03-17" => ["data_values" => 1],
"2019-03-18" => ["data_values" => 2],
"2019-03-19" => ["data_values" => 3],
"2019-03-20" => ["data_values" => 4]
];
$result = implode_r($output);
echo $result['dates'];
echo $result['data_values'];
I need the array as (2) from a single query
can anyone help ?
1. Array
(
[0] => Array
(
[crop_id] => 3
[crop_name] => Barley
)
2. Array
(
[0] => Array
(
[Barley] => 3
)
)
Don't know about query but you can do that simply using array_map()
$array[] = array('crop_id' => 3, 'crop_name' => "Barley");
$result = array_map("myfunction",$array);
print_r($result);
function myfunction($v)
{
$data = [];
$data[$v['crop_name']] = $v['crop_id'];
return $data;
}
Let's suppose you have stored your data in array named as crop_data like
$crop_data[0][crop_id]=3;
$crop_data[0][crop_name]='Barley';
....
$crop_data[n][crop_id]=187;
$crop_data[n][crop_name]='Wheat'
Try this code:
$new_crop_result=array()
foreach($crop_data as $key=>$record)
{
$new_crop_result[$key][$record[crop_name]]=$record[crop_id];
}

I'm trying to loop through an array that I got from preg_match_all result in order to create one string from all results.
Array looks like this:
print_r($matches[0]);
Array
(
[0] => Array
(
[0] => 8147
[1] => 3
)
[1] => Array
(
[0] => 8204
[1] => 20
)
)
And my code:
$found = count($matches[0]);
for ($i = 0; $i <= $found; $i++) {
$string = $matches[0][$i];
}
I would like to get result of $string like this: 8147, 8204.
How I can append $matches[0][0] to $matches[0][1] etc. in string variable using loop?
You can do this some ting like that
$string = "";
foreach($matches[0] as $value) {
$string .= $value[0].", ";
}
$string = rtrim(", ",$string);
With php5.5 and more you can use array_column + implode:
echo implode(', ', array_column($matches, 0));
Try following code. Loop through array and get values
$arr =Array
(
0 => Array
(
0 => 8147,
1 => 3
),
1 => Array
(
0 => 8204,
1 => 20
)
);
$match_array = array();
foreach($arr as $key=>$value)
{
$match_array[] = $value[0];
}
$str = implode(",",$match_array);
echo $str;
DEMO
OR simply use array_column to get specific column as array then use implode
$arr =Array
(
0 => Array
(
0 => 8147,
1 => 3
),
1 => Array
(
0 => 8204,
1 => 20
)
);
$match_array = array_column($arr,0);
$str = implode(",",$match_array);
echo $str;
DEMO
You can use array_column, no need to loop over the array
$result = join(',', array_column($arr, 0));

Is there a function to extract a 'column' from an array in PHP?

I have an array that looks like this:
Array (
[0] => Array ([order_variable_key] => surname [order_variable_value] => Hudsons )
[1] => Array ( [order_variable_key] => number [order_variable_value] => 13 )
[2] => Array ( [order_variable_key] => firstname [order_variable_value] => Dave )
)
I want to convert it to an array that looks like this:
Array(
'surname' => Hudsons,
'number' => 13,
'firstname' => Dave);
I managed to isolate the values but was not able to pair them with eachother.
I want to pair the values of the nested array with eachother.
$new_array= array();
foreach($array_name1 as $key=>$val){
$new_array[$val['order_variable_key']] = $val['order_variable_value'];
}
you can use
$newArray = array();
foreach($array as $obj)
{
$newArray[$obj['order_variable_key']] = $obj['order_variable_value']
}
Try this:
$arr = // your array;
$data = array();
foreach($arr as $val)
{
$arr[$val['order_variable_key']] = $val['order_variable_value'];
}
print_r($arr);
will give your desired format.

Here's a section my multidimensional array:
Array (
[0] => Array ( [0] => Height [1] => 40 )
[1] => Array ( [0] => Weight [1] => 15 )
[2] => Array ( [0] => Ctr_Percent [1] => 15 )
)
What would the syntax be for just printing height, weight, and ctr_percent? I don't mean echoing it like:
echo $array[0][0];
echo $array[1][0];
Is there a way to iterate through the entire multidimensional array and echo out the first value of each child array?
Supposing you use php 5.3:
$first_elements = array_map(function($i) {
return $i[0];
}, $data);
Otherwise you need to implement a callback function or just use plain old foreach
Here is a one-liner:
array_map('array_shift', $array);
Will return:
Array
(
[0] => Height
[1] => Weight
[2] => Ctr_Percent
)
And here is another one:
array_combine(array_map('array_shift', $temp), array_map('array_pop', $temp))
Will return:
Array
(
[Height] => 40
[Weight] => 15
[Ctr_Percent] => 15
)
Use array_column:
$result = array_column($array, 0);
foreach ($main_array as $inner_array){
echo $inner_array[0] . "\n";
}
foreach($array as $x) {
echo $x[0]."\n";
}
I think the function your looking for is reset() e.g.
array_map('reset', $array);
or
foreach ($array as $subarray)
echo reset($subarray)."\n";
Note that this works even if 0 is not the first index of the array. E.g. $a = [1=>5,0=>3]; echo reset($a); would still echo 5;.
The easiest way to do it using array_walk
function getFirstElement(&$val){
$val = $val[0];
}
array_walk($data,'getFirstElement');
Now if you print $data like print_r($data); you will get result as below
Array
(
[0] => Height
[1] => Weight
[2] => Ctr_Percent
)
