Hi I have an array just like below
$arr = array ( [0] => Array ( [allergy] => test ),[1] => Array ( [allergy] => test1 ) );
Here from that array I just want allergy value as comma separated string like test,test1
I tried implode but it's not working
$arr = array ( [0] => Array ( [allergy] => test ),[1] => Array ( [allergy] => test1 ) );
$str = implode (", ", $arr);
echo $str;
here is my sample
//array_column will work from php version 5.5,
$arr = array ( '0' => Array ( 'allergy' => 'test' ),'1' => Array ( 'allergy' => 'test1' ) );
$str = '';
foreach($arr as $row){
$str .=$row['allergy'].',';
}
$str = trim($str,',');
echo $str;
You can use array_column() for that, and then use implode() to comma separated string.
Your code might look something like this,
$arr = array (array ('allergy' => 'test'),array ('allergy' => 'test1') );
$arr=array_column($arr,"allergy");
$str = implode (",", $arr);
echo $str;
array_column() returns the values from a single column of the input, identified by the second parameter(column_key).
