## 説明

This function is identical to ereg() 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.

## 戻り値

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.
