Convert comma separated string to array and test for entries
Ensure no trailing comma that will produce a blank final array entry
$MyCommaSeperatedString = rtrim(trim("abc,def,ghi,"), ","); //Ensure there is no trailing comma
$MyArray = explode(',', $MyCommaSeperatedString); //Convert to array (No commas will result in the text in the string being in an array of length 1)
print_r($MyArray);
//Will output: Array ( [0] => abc [1] => def [2] => ghi )Examples
$MyCommaSeperatedString = "abc,def,ghi";
$MyArray = explode(',', $MyCommaSeperatedString); //Convert to array (No commas will result in the text in the string being in an array of length 1)
print_r($MyArray);
//Will output: Array ( [0] => abc [1] => def [2] => ghi )
$MyCommaSeperatedString = "abc,def,ghi,";
$MyArray = explode(',', $MyCommaSeperatedString); //Convert to array (No commas will result in the text in the string being in an array of length 1)
print_r($MyArray);
//Will output: Array ( [0] => abc [1] => def [2] => ghi [3] => )
$MyCommaSeperatedString = rtrim(trim("abc,def,ghi,"), ","); //Ensure there is no trailing comma
$MyArray = explode(',', $MyCommaSeperatedString); //Convert to array (No commas will result in the text in the string being in an array of length 1)
print_r($MyArray);
//Will output: Array ( [0] => abc [1] => def [2] => ghi )Convert array into comma separated string
$MyArray = array();
$MyArray[] = 'abc';
$MyArray[] = 'def';
$MyArray[] = 'ghi';
$MyCommaSeperatedString = implode(',', $MyArray); //Convert array to comma seperated string
echo $MyCommaSeperatedString . "<br>";
//Will output: abc,def,ghi
