==============

PHP 包，允许您将字符串解析为序列。

安装

使用 Composer 需求此包

composer require fuitad/string-sequencer

使用方法

在您的 PHP 文件中导入类

use \Fuitad\StringSequencer;

static from() 方法

use \Fuitad\StringSequencer;

$str = "http://www.google.com/page[:1:1:5:].html";
$result = StringSequencer::from($str);

将返回。

array:5 [
  0 => "http://www.google.com/page1.html"
  1 => "http://www.google.com/page2.html"
  2 => "http://www.google.com/page3.html"
  3 => "http://www.google.com/page4.html"
  4 => "http://www.google.com/page5.html"
]

static multi() 方法

$str = "http://www.google.com/page[:1:1:5:]-[:20:5:40:].html";
$result = StringSequencer::multi($str);

将返回。

array:25 [
  0 => "http://www.google.com/page1-20.html"
  1 => "http://www.google.com/page1-25.html"
  2 => "http://www.google.com/page1-30.html"
  3 => "http://www.google.com/page1-35.html"
  4 => "http://www.google.com/page1-40.html"
  5 => "http://www.google.com/page2-20.html"
  6 => "http://www.google.com/page2-25.html"
  7 => "http://www.google.com/page2-30.html"
  8 => "http://www.google.com/page2-35.html"
  9 => "http://www.google.com/page2-40.html"
  10 => "http://www.google.com/page3-20.html"
  11 => "http://www.google.com/page3-25.html"
  12 => "http://www.google.com/page3-30.html"
  13 => "http://www.google.com/page3-35.html"
  14 => "http://www.google.com/page3-40.html"
  15 => "http://www.google.com/page4-20.html"
  16 => "http://www.google.com/page4-25.html"
  17 => "http://www.google.com/page4-30.html"
  18 => "http://www.google.com/page4-35.html"
  19 => "http://www.google.com/page4-40.html"
  20 => "http://www.google.com/page5-20.html"
  21 => "http://www.google.com/page5-25.html"
  22 => "http://www.google.com/page5-30.html"
  23 => "http://www.google.com/page5-35.html"
  24 => "http://www.google.com/page5-40.html"

格式化

您还可以添加一个与 sprintf 兼容的模式来格式化输出。

$str = "http://www.google.com/page[:1:1:5:%02d:].html";
$result = StringSequencer::from($str);

将返回

array:5 [
  0 => "http://www.google.com/page01.html"
  1 => "http://www.google.com/page02.html"
  2 => "http://www.google.com/page03.html"
  3 => "http://www.google.com/page04.html"
  4 => "http://www.google.com/page05.html"
]

反向引用

如果您需要在字符串中多次执行相同的迭代（而不是在字符串上执行不同的迭代），您可以使用反向引用。请注意，虽然语法看起来有点像正则表达式的反向引用，但实际上不是。

$str = "http://www.google.com/page[:1:1:5:%02d:]/[\\1].html";
$result = StringSequencer::from($str);

将返回。

array:5 [
  0 => "http://www.google.com/page1/1.html"
  1 => "http://www.google.com/page2/2.html"
  2 => "http://www.google.com/page3/3.html"
  3 => "http://www.google.com/page4/4.html"
  4 => "http://www.google.com/page5/5.html"
