Bug description:preg_match return false for using (\$)
Description:
------------
I using worksheet de pear(library parse.php, found problem for preg_match)
$token='=sum($a1:$a1);
if
(preg_match("/^(\$)?[A-Ia-i]?[A-Za-z](\$)?[0-9]+:(\$)?[A-Ia-i]?[A-Za-z](\$)?[0-9]+$/",$token))
{
...
}
no true
$token='=sum(a1:a1);
if
(preg_match("/^(\$)?[A-Ia-i]?[A-Za-z](\$)?[0-9]+:(\$)?[A-Ia-i]?[A-Za-z](\$)?[0-9]+$/",$token))
{
...
}
is true
Test script:
---------------
$ change another different character and no problem sample @
$token='=sum(@a1:@a1);
if
(preg_match("/^(\@)?[A-Ia-i]?[A-Za-z](\@)?[0-9]+:(\@)?[A-Ia-i]?[A-Za-z](\@)?[0-9]+$/",$token))
{
...
}
After trying other caracters I found that the problem is that the $ replace
internal a point (.) character 46
$token='=sum($a1:$a1);
if
(preg_match("/^(.)?[A-Ia-i]?[A-Za-z](.)?[0-9]+:(.)?[A-Ia-i]?[A-Za-z](.)?[0-9]+$/",$token))
{
...
}
here if there was affirmative result for dollar ($) and point (.)
Expected result:
----------------
true for (\$) for preg_match
Actual result:
--------------
false for (\$) for preg_match
