Getting Warning: split(): REG_BADRPT when using the split PHP function

Getting Warning: split(): REG_BADRPT when using the split PHP function when I try to split a string after each question mark (?).

E.g.

$string = "ABC?DEF?BGT";
list($a,$b) = split('?',$string);

Answer:

• The reason why this is failing is split gives you the power to use regular expressions
• Use the explode() function instead
• If you really need to use the split() function try escaping the character eg. ‘/\?/’
