this language construct terminates parsing of the script. it does not return.
exit statuses should be in the range 1 to 254, the exit status 255 is reserved by php and shall not be used.

there are certain php.ini directives which are overriden by the cli sapi because they do not make sense in shell environments:

open text file for reading and writing. the file is created if it does not exist. the stream is positioned at the end of the file.
options affects how the path / url of the stream is interpreted, safe mode checks and actions taken if there is an error during opening of the stream.

extract() checks each key to see if it constitues a valid variable name, and if it does only then does it proceed to import it.
you can use this flag on its own or combine it with any other flag by or 'ing the extract_type.

open text file for reading and writing. the file is created if it does not exist, otherwise it is truncated. the stream is positioned at the beginning of the file.
the stream is positioned at the beginning of the file.

참고: if you need to seek and write to the stream, it does not make sense to use this function, because the stream it returns is not guaranteed to be bound to the same resource as the original stream.
an error occurred while attempting conversion that has left origstream in an indeterminate state. newstream is set to null and it is highly recommended that you close origstream.

this program is extremely simple and you really didn't need to use php to create a page like this. all it does is display: hello world using the php echo() statement.

an assertion is a test on the characters following or preceding the current matching point that does not actually consume any characters. the simple assertions coded as \b, \b, \a, \z, \z, ^ and $are described above. more complicated assertions are coded as subpatterns. there are two kinds: those that look ahead of the current position in the subject string, and those that look behind it. an assertion subpattern is matched in the normal way, except that it does not cause the current matching position to be changed. lookahead assertions start with (?= for positive assertions and (?! for negative assertions. for example, \w+(?=;) matches a word followed by a semicolon, but does not include the semicolon in the match, and foo(?!bar) matches any occurrence of "foo" that is not followed by "bar". note that the apparently similar pattern (?!foo)bar does not find an occurrence of "bar" that is preceded by something other than "foo"; it finds any occurrence of "bar" whatsoever, because the assertion (?!foo) is always true when the next three characters are "bar". a lookbehind assertion is needed to achieve this effect. lookbehind assertions start with (? = for positive assertions and (?! for negative assertions. for example, (? !foo)bar does find an occurrence of "bar" that is not preceded by "foo". the contents of a lookbehind assertion are restricted such that all the strings it matches must have a fixed length. however, if there are several alternatives, they do not all have to have the same fixed length. thus (? =bullock_bar_donkey) is permitted, but (? !dogs?_bar_cats?) causes an error at compile time. branches that match different length strings are permitted only at the top level of a lookbehind assertion. this is an extension compared with perl 5.005, which requires all branches to match the same length of string. an assertion such as (? =ab(c_bar_de)) is not permitted, because its single top-level branch can match two different lengths, but it is acceptable if rewritten to use two top-level branches: (? =abc_bar_abde) the implementation of lookbehind assertions is, for each alternative, to temporarily move the current position back by the fixed width and then try to match. if there are insufficient characters before the current position, the match is deemed to fail. lookbehinds in conjunction with once-only subpatterns can be particularly useful for matching at the ends of strings; an example is given at the end of the section on once-only subpatterns. several assertions (of any sort) may occur in succession. for example, (? =\d{3})(? !999)foo matches "foo" preceded by three digits that are not "999". notice that each of the assertions is applied independently at the same point in the subject string. first there is a check that the previous three characters are all digits, then there is a check that the same three characters are not "999". this pattern does not match "foo" preceded by six characters, the first of which are digits and the last three of which are not "999". for example, it doesn't match "123abcfoo". a pattern to do that is (? =\d{3}...)(? !999)foo this time the first assertion looks at the preceding six characters, checking that the first three are digits, and then the second assertion checks that the preceding three characters are not "999". assertions can be nested in any combination. for example, (? =(? !foo)bar)baz matches an occurrence of "baz" that is preceded by "bar" which in turn is not preceded by "foo", while (? =\d{3}(?!999)...)foo is another pattern which matches "foo" preceded by three digits and any three characters that are not "999". assertion subpatterns are not capturing subpatterns, and may not be repeated, because it makes no sense to assert the same thing several times. if any kind of assertion contains capturing subpatterns within it, these are counted for the purposes of numbering the capturing subpatterns in the whole pattern. however, substring capturing is carried out only for positive assertions, because it does not make sense for negative assertions. assertions count towards the maximum of 200 parenthesized subpatterns.
it is more efficient to use a character class like [aeiou] than a set of alternatives such as (a_bar_e_bar_i_bar_o_bar_u).
