Could you please explain me what the below code do?
if ($max<$delim{$&}++)
{
$destr=$&; # assign the delimiter string to a variable
$max=$delim{$&}; # reset the maximum number
}
I havenot used $& so far. And in the for loop you have given only $file[0] which means it reads only the first line of the file. Please correct me If i am wrong.

I have a file in which the following pattern is there
TAG001^A<value>^A
I want to find all such values(words) which comes right next to "TAG001^A" and before the next "^A".
^A is the delimiter here.

preg_quote
PREG_QUOTE(3) 1 PREG_QUOTE(3)preg_quote - Quote regular expression charactersSYNOPSIS
string preg_quote NULL (string $str, [string $delimiter])
DESCRIPTION preg_quote(3) takes $str and puts a backslash in front of every character that is part of the regular expression syntax. This is useful if
you have a run-time string that you need to match in some text and the string may contain special regex characters.
The special regular expression characters are: . + * ? [ ^ ] $ ( ) { } = ! < > | : -
PARAMETERS
o $str
- The input string.
o $delimiter
- If the optional $delimiter is specified, it will also be escaped. This is useful for escaping the delimiter that is required by
the PCRE functions. The / is the most commonly used delimiter.
RETURN VALUES
Returns the quoted (escaped) string.
