I have a string variable that has multiple values in the following format:

123, xyz, abc

It may even have a single value only (in that case there wont be any comma after it)

How do I parse through these values in a for loop, going over each value at a time?

$input="123, xyz, abc"; 
foreach (explode(",",$input) as $value) { 
    var_dump(trim($value)); 
}

the code does not work when the variable has just a single value without any comma after it- what do I do in that case? (I ran your code and checked). –  Arvind Jun 15 '13 at 14:05

It works fine here: $input="123"; foreach (explode(",",$input) as $value) { var_dump(trim($value)); } string(3) "123" –  faffaffaff Jun 15 '13 at 14:06

Try to explode with comma ',' like

$your_arr = "123,xyz,....";
$my_arr = explode(",",$your_arr);
foreach($my_arr as $arr) {
      echo $arr;
      //Do the stuff HERE
}
