hi
Here is my code written to identify the particular position which is after a string (chr*). my input file looks some thing like this
i wanted to get the @pos as the immediate occurance after chr* as there are 2 such occurances in each line the first occrance has to be stored in pos[0] and second in pos[1] for pos[0] pattern search has to be made wih in pos[0]+6 characters and same vs for pos[1] but backwards

strripos
STRRIPOS(3) 1 STRRIPOS(3)strripos - Find the position of the last occurrence of a case-insensitive substring in a stringSYNOPSIS
int strripos (string $haystack, string $needle, [int $offset])
DESCRIPTION
Find the numeric position of the last occurrence of $needle in the $haystack string.
Unlike the strrpos(3), strripos(3) is case-insensitive.
PARAMETERS
o $haystack
- The string to search in.
o $needle
- If $needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
o $offset
- If specified, search will start this number of characters counted from the beginning of the string. If the value is negative,
search will instead start from that many characters from the end of the string, searching backwards.
RETURN VALUES
Returns the position where the needle exists relative to the beginnning of the $haystack string (independent of search direction or off-
set). Also note that string positions start at 0, and not 1.
Returns FALSE if the needle was not found.
Warning
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
Booleans for more information. Use the === operator for testing the return value of this function.
EXAMPLES
Example #1
A simple strripos(3) example
<?php
$haystack = 'ababcd';
$needle = 'aB';
$pos = strripos($haystack, $needle);
if ($pos === false) {
echo "Sorry, we did not find ($needle) in ($haystack)";
} else {
echo "Congratulations!
";
echo "We found the last ($needle) in ($haystack) at position ($pos)";
}
?>
The above example will output:
Congratulations!
We found the last (aB) in (ababcd) at position (2)
