[php-maint] Bug#349978: php4: Regression bug in ctype_digit() function

[Andrew Rolfe]

Package: php4
Version: 4:4.4.2-1
Severity: normal


php4 version 4:4.4.2-1 will return false if ctype_digit() is passed an
empty string. However 4:4.4.0-4 will return true. This causes unexpected
results in existing programs.

Example on 4:4.4.0-4:
<?php var_dump(ctype_digit('')); ?>
returns: bool(true)

Example on 4:4.4.2-1:
<?php var_dump(ctype_digit('')); ?>
Returns: bool(false)
