- Pattern Modifiers
- Describes possible modifiers in regex
- patterns
-
-
- Description
-
- The current possible PCRE modifiers are listed below. The names
- in parentheses refer to internal PCRE names for these modifiers.
-
-
-
-
-
- i (PCRE_CASELESS)
-
-
- If this modifier is set, letters in the pattern match both
- upper and lower case letters.
-
-
-
-
- m (PCRE_MULTILINE)
-
-
- By default, PCRE treats the subject string as consisting of a
- single "line" of characters (even if it actually contains
- several newlines). The "start of line" metacharacter (^)
- matches only at the start of the string, while the "end of
- line" metacharacter ($) matches only at the end of the
- string, or before a terminating newline (unless
- D modifier is set). This is the same as
- Perl.
-
-
- When this modifier is set, the "start of line" and "end of
- line" constructs match immediately following or immediately
- before any newline in the subject string, respectively, as
- well as at the very start and end. This is equivalent to
- Perl's /m modifier. If there are no "\n" characters in a
- subject string, or no occurrences of ^ or $ in a pattern,
- setting this modifier has no effect.
-
-
-
-
- s (PCRE_DOTALL)
-
-
- If this modifier is set, a dot metacharacter in the pattern
- matches all characters, including newlines. Without it,
- newlines are excluded. This modifier is equivalent to Perl's
- /s modifier. A negative class such as [^a] always matches a
- newline character, independent of the setting of this
- modifier.
-
-
-
-
- x (PCRE_EXTENDED)
-
-
- If this modifier is set, whitespace data characters in the
- pattern are totally ignored except when escaped or inside a
- character class, and characters between an unescaped #
- outside a character class and the next newline character,
- inclusive, are also ignored. This is equivalent to Perl's /x
- modifier, and makes it possible to include comments inside
- complicated patterns. Note, however, that this applies only
- to data characters. Whitespace characters may never appear
- within special character sequences in a pattern, for example
- within the sequence (?( which introduces a conditional
- subpattern.
-
-
-
-
- e
-
-
- If this modifier is set, preg_replace
- does normal substitution of backreferences in the
- replacement string, evaluates it as PHP code, and uses the
- result for replacing the search string.
- Single and double quotes are escaped by backslashes in substituted
- backreferences.
-
-
- Only preg_replace uses this modifier;
- it is ignored by other PCRE functions.

+
+
+
+
+ i (PCRE_CASELESS)
+
- This modifier was not available in PHP 3.
+ If this modifier is set, letters in the pattern match both
+ upper and lower case letters.
-
-
-
-
-
- A (PCRE_ANCHORED)
-
-
- If this modifier is set, the pattern is forced to be
- "anchored", that is, it is constrained to match only at the
- start of the string which is being searched (the "subject
- string"). This effect can also be achieved by appropriate
- constructs in the pattern itself, which is the only way to
- do it in Perl.
-
-
-
-
- D (PCRE_DOLLAR_ENDONLY)
-
-
- If this modifier is set, a dollar metacharacter in the pattern
- matches only at the end of the subject string. Without this
- modifier, a dollar also matches immediately before the final
- character if it is a newline (but not before any other
- newlines). This modifier is ignored if m
- modifier is set. There is no equivalent to this modifier in
- Perl.
-
-
-
-
- S
-
-
- When a pattern is going to be used several times, it is
- worth spending more time analyzing it in order to speed up
- the time taken for matching. If this modifier is set, then
- this extra analysis is performed. At present, studying a
- pattern is useful only for non-anchored patterns that do not
- have a single fixed starting character.
-
-
-
-
- U (PCRE_UNGREEDY)
-
-
- This modifier inverts the "greediness" of the quantifiers so
- that they are not greedy by default, but become greedy if
- followed by "?". It is not compatible with Perl. It can also
- be set by a (?U)
- modifier setting within
- the pattern or
-
-
-
-
- X (PCRE_EXTRA)
-
-
- This modifier turns on additional functionality of PCRE that
- is incompatible with Perl. Any backslash in a pattern that
- is followed by a letter that has no special meaning causes
- an error, thus reserving these combinations for future
- expansion. By default, as in Perl, a backslash followed by a
- letter with no special meaning is treated as a literal.
- There are at present no other features controlled by this
- modifier.
-
-
-
-
- u (PCRE_UTF8)
-
-
- This modifier turns on additional functionality of PCRE that
- is incompatible with Perl. Pattern strings are treated as
- UTF-8. This modifier is available from PHP 4.1.0 or greater
- on Unix and from PHP 4.2.3 on win32.
