Array to comma separated string? - php

Question

My php code is
public function getAllAttributes()
{
$this->dao->select('b_title');
$this->dao->from($this->getTable_buttonsAttr());
$result = $this->dao->get();
if( !$result ) {
return array() ;
}
return $result->result();
}
$details = Modelbuttons::newInstance()->getAllAttributes();
$string = implode(', ', $details);
var_dump ($string) ; ?>
I get this an array that looks like this:
array (size=6)
0 =>
array (size=1)
'b_title' => string 'test 10' (length=12)
1 =>
array (size=1)
'b_title' => string 'test 11' (length=12)
2 =>
array (size=1)
'b_title' => string 'test 12' (length=13)
3 =>
array (size=1)
'b_title' => string 'test 13' (length=8)
4 =>
array (size=1)
'b_title' => string 'test 14' (length=14)
5 =>
array (size=1)
'b_title' => string 'test 15' (length=32)
How can I transform this array to a string like this with PHP?
$out = '10, 11, 12, 13, 14,15';

Answer 1

You can try this code.
$array = [['b_title' => 'test 10'],['b_title' => 'test 11']];
foreach($array as $a) {
$values[] = explode(' ', $a['b_title'])[1];
}
echo implode(', ', $values);

Answer 2

Basic Example:
<?php
// your array
$array = array(
array('b_title'=>'test 10'),
array('b_title'=>'test 11'),
array('b_title'=>'test 12'),
array('b_title'=>'test 13')
);
$newArr = array();
foreach ($array as $key => $value) {
$newVal = explode(" ", $value['b_title']);
$newArr[] = $newVal[1];
}
echo implode(',', $newArr); // 10,11,12,13
?>
Explanation:
First of all use explode() for your string value which help you to Split a string as required:
$newVal = explode(" ", $value['b_title']);
Than you can store index 1 in an array as:
$newArr[] = $newVal[1]; // array(10,11,12,13)
In last, you just need to use implode() function which help you to get comma separated data.
echo implode(',', $newArr); // 10,11,12,13

Answer 3

An alternative way to do.
$details = Modelbuttons::newInstance()->getAllAttributes(); /*[['b_title' => 'test 10'],['b_title' => 'test 11']];*/
$token = "";
foreach($details as $row1){
$token = $token.$row1['b_title'].", ";
}
echo rtrim(trim($token),",");
Output: test 10, test 11
Explanation
Through foreach, all array values are now comma separated.
As of now, output will be test 10, test 11,. So, remove extra comma which trail in the end through rtrim().

Answer 4

There are many ways to skin this cat -- Here's one:
<?php
$out = '';
foreach ($array as $arrayItem) {
$out .= $arrayItem['b_title'] . ', ';
}
// Remove the extraneous ", " from the $out string.
$out = substr($out, 0, -2);
?>
Or if you were also wanting to remove the "test " portion of the 'b_title' key's value; then you could accomplish it like so:
<?php
$out = '';
foreach ($array as $arrayItem) {
$out .= str_replace('test ', '', $arrayItem['b_title']) . ', ';
}
// Remove the extraneous ", " from the $out string.
$out = substr($out, 0, -2);
?>

Answer 5

// Construct a new array of the stripped numbers
$flattenedArray = array_map(function($item) {
list(, $number) = explode(' ', $item['b_title']);
return $number;
}, $yourArray);
// Concatenate the numbers into a string joined by ,
$out = implode(', ', $flattenedArray);
This gives the result you want. It could do with a few conditions in there though to check arrays are in the correct format before manipulation etc.

Answer 6

You can try this also
$check = array(array ('b_title' => array('test 10'))
,array('b_title' => array('test 11'))
,array('b_title' => array('test 12'))
,array('b_title' => array('test 13'))
,array('b_title' => array('test 14'))
,array('b_title' => array('test 15')));
$srt = "";
foreach($check as $kye => $val)
{
$title = $val['b_title'][0];
$var = explode(' ',$title);
$srt .= trim($var[1]).', ';
}
$srt = substr(trim($srt),0,-1);

Answer 7

$test_array = array(
0 => array('b_title' => 'test 10'),
1 => array('b_title' => 'test 11'),
2 => array('b_title' => 'test 12'),
3 => array('b_title' => 'test 13'),
4 => array('b_title' => 'test 14'),
5 => array('b_title' => 'test 15'),
);
$result = "";
$result1 = array_walk($test_array, function ($value, $key) use(&$result) {
$result .= ",".array_pop(explode(" ", reset($value))).",";
$result = trim($result, ",");
});
Output: $out = '10, 11, 12, 13, 14,15';
Explanation
Iterate over array by using PHP's native array_walk() which will reduce forloops and then prepare array by using explode(),array_pop() and trim() which is likely required to prepare your required string.

Answer 8

Try this,
foreach($test_array as $val)
{
$new_array[] = preg_replace('/\D/', '', $val['b_title']);
}
$out = implode(',', $new_array);
echo $out;
OUTPUT
10,11,12,13,14,15

Answer 9

You can use on mentioned URL solution Click here
foreach ($arr as $k=>$val) {
$v = explode (' ', $val['b_title']);
$out .= $v[1].',';
}
$out = rtrim ($out, ',');
echo '<pre>'; print_r($out); die;
