Try this to return the value before the 2nd "ABCXYZ":
Code:
csv (.*)ABCXYZ

Match the characters "csv " literally
Match the regular expression below and capture its match into backreference number 1
   Match any single character that is not a line break character
      Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
Match the characters "ABCXYZ" literally


$result = preg_replace('/csv (.*)ABCXYZ/im', '$1', $subject);

eregi - Case insensitive regular expression match

SYNOPSIS
int eregi (string $pattern, string $string, [array &$regs]) DESCRIPTION
This function is identical to ereg(3) except that it 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. o $string - The input string. o $regs - If matches are found for parenthesized substrings of $pattern and the function is called with the third argument $regs, the matches will be stored in the elements of the array $regs. $regs[1] will contain the substring which starts at the first left parenthesis; $regs[2] will contain the substring starting at the second, and so on. $regs[0] will contain a copy of the complete string matched. RETURN VALUES
Returns the length of the matched string if a match for $pattern was found in $string, or FALSE if no matches were found or an error occurred. If the optional parameter $regs was not passed or the length of the matched string is 0, this function returns 1. EXAMPLES
Example #1 eregi(3) example <?php $string = 'XYZ'; if (eregi('z', $string)) { echo "'$string' contains a 'z' or 'Z'!"; } ?> 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 eregi(3) is deprecated as of PHP 5.3.0. preg_match(3) with the i ( PCRE_CASELESS) modifier is the suggested alternative. SEE ALSO
ereg(3), ereg_replace(3), eregi_replace(3), preg_match(3), stripos(3), stristr(3), quotemeta(3). PHP Documentation Group EREGI(3)
