I'm unfamiliar with the asterix as comment convention, however if you wish to skip from any occurrence of an asterix to the end of the line, you could capture the comment (or indeed ignore it, as follows:

Hey everyone,
Basically, all I'm looking for is a way to regex for not a certain string. The regex I'm looking to avoid matching is:
D222
i.e. an equivalent of:
awk '!/D222/'
The problem is that I use this in the following command in a Bash script:

Hi,
I find it really strange while writing a simple regex to match and print the matched string,

Hi,
I'm trying to match the front and back of a sequence. It works when there is an exact match (obviously), but I need the regex to be more flexible. When we get strings of nucleotides sometimes their prefixes and suffixes aren't exact matches. Sometimes there will be an extra letter and... (2 Replies)

spliti
SPLITI(3) 1 SPLITI(3)spliti - Split string into array by regular expression case insensitiveSYNOPSIS
array spliti (string $pattern, string $string, [int $limit = -1])
DESCRIPTION
Splits a $string into array by regular expression.
This function is identical to split(3) except that this ignores case distinction when matching alphabetic characters.
Warning
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
PARAMETERS
o $pattern
- Case insensitive regular expression. If you want to split on any of the characters which are considered special by regular
expressions, you'll need to escape them first. If you think spliti(3) (or any other regex function, for that matter) is doing
something weird, please read the file regex.7, included in the regex/ subdirectory of the PHP distribution. It's in manpage for-
mat, so you'll want to do something along the lines of man /usr/local/src/regex/regex.7 in order to read it.
o $string
- The input string.
o $limit
- If $limit is set, the returned array will contain a maximum of $limit elements with the last element containing the whole rest
of $string.
RETURN VALUES
Returns an array of strings, each of which is a substring of $string formed by splitting it on boundaries formed by the case insensitive
regular expression $pattern.
If there are n occurrences of $pattern, the returned array will contain n+1 items. For example, if there is no occurrence of $pattern, an
array with only one element will be returned. Of course, this is also true if $string is empty. If an error occurs, spliti(3) returns
FALSE.
EXAMPLES
This example splits a string using 'a' as the separator :
Example #1
spliti(3) example
<?php
$string = "aBBBaCCCADDDaEEEaGGGA";
$chunks = spliti ("a", $string, 5);
print_r($chunks);
?>
The above example will output:
Array
(
[0] =>
[1] => BBB
[2] => CCC
[3] => DDD
[4] => EEEaGGGA
)
NOTES
Note
As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED
notice. See the list of differences for help on converting to PCRE.
Tip
spliti(3) is deprecated as of PHP 5.3.0. preg_split(3) with the i ( PCRE_CASELESS) modifier is the suggested alternative.
SEE ALSO preg_split(3), split(3), explode(3), implode(3).
