I have a string which contains numbers separated by commas. It may or may not have a space in between the numbers and a comma in the end. I want to convert it into an array, that I can do using following code:
$string = '1, 2,3,';
$array = explode(',', $string);
However the additional irregular spaces gets in the array values and the last comma causes an empty index (see image below).
How can I remove that so that I get only clean values without spaces and last empty index in the array?
