The RegexIterator class

(PHP 5 >= 5.2.0, PHP 7)

简介

This iterator can be used to filter another iterator based on a regular expression.

RegexIterator extends FilterIterator {

/* 常量 */

const int MATCH = 0 ;

const int GET_MATCH = 1 ;

const int ALL_MATCHES = 2 ;

const int SPLIT = 3 ;

const int REPLACE = 4 ;

const int USE_KEY = 1 ;

/* 方法 */

public __construct ( Iterator $iterator , string $regex , int $mode = self::MATCH , int $flags = 0 , int $preg_flags = 0 )

public accept ( ) : bool

public getFlags ( ) : int

public getMode ( ) : int

public getPregFlags ( ) : int

public getRegex ( ) : string

public setFlags ( int $flags ) : void

public setMode ( int $mode ) : void

public setPregFlags ( int $preg_flags ) : void

/* 继承的方法 */

public abstract FilterIterator::accept ( ) : bool

public FilterIterator::__construct ( Iterator $iterator )

public FilterIterator::key ( ) : mixed

public FilterIterator::next ( ) : void

public FilterIterator::rewind ( ) : void

public FilterIterator::valid ( ) : bool

}

RegexIterator::ALL_MATCHES: Return all matches for the current entry (see preg_match_all()).
RegexIterator::GET_MATCH: Return the first match for the current entry (see preg_match()).
RegexIterator::MATCH: Only execute match (filter) for the current entry (see preg_match()).
RegexIterator::REPLACE: Replace the current entry (see preg_replace(); Not fully implemented yet)
RegexIterator::SPLIT: Returns the split values for the current entry (see preg_split()).

RegexIterator::USE_KEY: Special flag: Match the entry key instead of the entry value.
