PHP的易读正则表达式

release release phpunit release release

regexpbuilderjs的PHP端口

RegExpBuilder将正则表达式集成到编程语言中,因此使它们易于阅读和维护。正则表达式通过使用链式方法和变量(如数组或字符串)创建。

安装

composer req gherkins/regexpbuilderphp

或下载适当的版本,并从/src中require RegExpBuilder.phpRegExp.php

示例

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

验证

$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");

搜索

$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");

替换

$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);

使用多个模式的验证

$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");
