PREG_PATTERN_ORDER
(int)
|
Orders results so that $matches[0] is an array of full pattern
matches, $matches[1] is an array of strings matched by the first
parenthesized subpattern, and so on. This flag is only used with
preg_match_all.
|
|
PREG_SET_ORDER
(int)
|
Orders results so that $matches[0] is an array of first set of
matches, $matches[1] is an array of second set of matches, and so
on. This flag is only used with preg_match_all.
|
|
PREG_OFFSET_CAPTURE
(int)
|
See the description of
PREG_SPLIT_OFFSET_CAPTURE.
|
|
PREG_SPLIT_NO_EMPTY
(int)
|
This flag tells preg_split to return only non-empty
pieces.
|
|
PREG_SPLIT_DELIM_CAPTURE
(int)
|
This flag tells preg_split to capture
parenthesized expression in the delimiter pattern as well.
|
|
PREG_SPLIT_OFFSET_CAPTURE
(int)
|
If this flag is set, for every occurring match the appendant string
offset will also be returned. Note that this changes the return
values in an array where every element is an array consisting of the
matched string at offset 0 and its string offset within subject at
offset 1. This flag is only used for preg_split.
|
|
PREG_UNMATCHED_AS_NULL
(int)
|
This flag tells preg_match and
preg_match_all to include unmatched subpatterns in
$matches as null values. Without this flag, unmatched
subpatterns are reported as empty strings, as if they were empty matches.
Setting this flag allows to distinguish between these two cases.
