ANSI is a PHP based library which provides a sequential increment in an alpha numeric string order like this:
Old String - ZZZ
New String - 1000
Old String - DASD231DASDA12Z
New String - DASD231DASDA130
Old String - 000000000000000
New String - 000000000000001
Old String - zzzzzzzzzzzzzzzz
New String - 10000000000000000
Old String - edwaeqweq31321eae2131ea19
New String - edwaeqweq31321eae2131ea1a
If a string or a part of string contains uppercase, lowercase or both. It will going to increment last character of string in the same case as it is provided in the input string & it will not effect rest of the string case. This following string contains both upper & lower cases. String has been increment in the same order, case(upper & lower case of string remains as it is provided) & last character 'G' has been successfully increment into the expected character 'H' without losing the character case had been provided in input string like this:
Old String - rweQW324eq321CDG
New String - rweQW324eq321CDH
If string contains special characters or any other characters then return output will an invalid string:
Old String - fdsad3!###
New String - Invalid String

require_once('ansi.php');
Create an object of class ANSI. Then call method StringSequence::increment($string) & display sequential incremented string like this:
$string = 'asdaW31RG2B3q';
echo 'Output - ' .StringSequence::increment($string); // Output - asdaW31RG2B3r
