This function is identical to ereg() except that it ignores case distinction when matching alphabetic characters.
Case insensitive regular expression.
The input string.
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.
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.
