PHP 的人類可讀正規表示式

regexpbuilderjs的 PHP 端口

RegExpBuilder 將正規表示式整合到程式語言中，從而使它們易於閱讀和維護。正規表示式是透過使用鍊式方法和變數（例如陣列或字串）來建立的。

安裝

composer req gherkins/regexpbuilderphp

或下載適當的版本並需要來自/src的RegExpBuilder.php和RegExp.php 。

範例

 use Gherkins  RegExpBuilderPHP ;
$ builder = new RegExpBuilder ();

驗證

 $ regExp = $ builder
    -> startOfInput ()
    -> exactly ( 4 )-> digits ()
    -> then ( " _ " )
    -> exactly ( 2 )-> digits ()
    -> then ( " _ " )
    -> min ( 3 )-> max ( 10 )-> letters ()
    -> then ( " . " )
    -> anyOf ( array ( " png " , " jpg " , " gif " ))
    -> endOfInput ()
    -> getRegExp ();

//true
$ regExp -> matches ( " 2020_10_hund.jpg " );
$ regExp -> matches ( " 2030_11_katze.png " );
$ regExp -> matches ( " 4000_99_maus.gif " );

//false
$ regExp -> matches ( " 123_00_nein.gif " );
$ regExp -> matches ( " 4000_0_nein.pdf " );
$ regExp -> matches ( " 201505_nein.jpg " );

搜尋

 $ regExp = $ builder
    -> multiLine ()
    -> globalMatch ()
    -> min ( 1 )-> max ( 10 )-> anythingBut ( " " )
    -> anyOf ( array ( " .pdf " , " .doc " ))
    -> getRegExp ();

$ text = ' Lorem ipsum dolor sit amet, consetetur sadipscing elitr,
sed diam nonumy SomeFile.pdf eirmod tempor invidunt ut labore et dolore
magna aliquyam erat, sed diam voluptua. At vero eos et accusam
et justo duo dolores et ea rebum. doc_04.pdf Stet clita kasd File.doc. '

$ matches = $ regExp -> findIn ( $ text );

//true
( $ matches [ 0 ] === " SomeFile.pdf " );
( $ matches [ 1 ] === " doc_04.pdf " );
( $ matches [ 2 ] === " File.doc " );

代替

 $ regExp = $ builder
    -> min ( 1 )
    -> max ( 10 )
    -> digits ()
    -> getRegExp ();

$ text = " 98 bottles of beer on the wall " ;

$ text = $ regExp -> replace (
    $ text ,
    function ( $ match ) {
        return ( int ) $ match + 1 ;
    }
);

//true
( " 99 bottles of beer on the wall " === $ text );

使用多種模式進行驗證

 $ a = $ builder
    -> startOfInput ()
    -> exactly ( 3 )-> digits ()
    -> anyOf ( array ( " .pdf " , " .doc " ))
    -> endOfInput ();

$ b = $ builder
    -> getNew ()
    -> startOfInput ()
    -> exactly ( 4 )-> letters ()
    -> then ( " .jpg " )
    -> endOfInput ();

$ regExp = $ builder
    -> getNew ()
    -> eitherFind ( $ a )
    -> orFind ( $ b )
    -> getRegExp ();

//true
$ regExp -> matches ( " 123.pdf " );
$ regExp -> matches ( " 456.doc " );
$ regExp -> matches ( " bbbb.jpg " );
$ regExp -> matches ( " aaaa.jpg " );

//false
$ regExp -> matches ( " 1234.pdf " );
$ regExp -> matches ( " 123.gif " );
$ regExp -> matches ( " aaaaa.jpg " );
$ regExp -> matches ( " 456.docx " );
