Thanks..Actually i tried with substr and it was working..
Later i encountered an error and thought that is related to to the substr function. But looks like it caused by something else.
Thanks for the response !!

Similar to that I am also trying an awk array and wanted to check if the array value match string "{5:{" , replace with 5: and assign it back to same array and print it.
But below code is not working its not able to replace the array value , instead its assigning whole command to msg_arr[i] and printing it
any solution for this?
as soon as i use "`" its giving me syntax error

preg_filter
PREG_FILTER(3) 1 PREG_FILTER(3)preg_filter - Perform a regular expression search and replaceSYNOPSIS
mixed preg_filter (mixed $pattern, mixed $replacement, mixed $subject, [int $limit = -1], [int &$count])
DESCRIPTION preg_filter(3) is identical to preg_replace(3) except it only returns the (possibly transformed) subjects where there was a match. For
details about how this function works, read the preg_replace(3) documentation.
RETURN VALUES
Returns an array if the $subject parameter is an array, or a string otherwise.
If no matches are found or an error occurred, an empty array is returned when $subject is an array or NULL otherwise.
EXAMPLES
Example #1
Example comparing preg_filter(3) with preg_replace(3)
<?php
$subject = array('1', 'a', '2', 'b', '3', 'A', 'B', '4');
$pattern = array('/d/', '/[a-z]/', '/[1a]/');
$replace = array('A:$0', 'B:$0', 'C:$0');
echo "preg_filter returns
";
print_r(preg_filter($pattern, $replace, $subject));
echo "preg_replace returns
";
print_r(preg_replace($pattern, $replace, $subject));
?>
The above example will output:
preg_filter returns
Array
(
[0] => A:C:1
[1] => B:C:a
[2] => A:2
[3] => B:b
[4] => A:3
[7] => A:4
)
preg_replace returns
Array
(
[0] => A:C:1
[1] => B:C:a
[2] => A:2
[3] => B:b
[4] => A:3
[5] => A
[6] => B
[7] => A:4
)
