任何类型字符的php正则表达式 [英] php regexp for any kind of character

问题描述

我使用这种模式:

'/({for) (\d+) (times})([\w+\d+{}]{0,})({endfor})/i'

转换

{for 3 times}App2{endfor}

在

App2  App2  App2 

但这不适用于:

{for 7 times}
    App2
{endfor}

<小时>

这是我很小的模板引擎的一小部分.

只是为了好玩

$mactos = Array(
    '/({for) (\d+) (times})([\w+\d+{}]{0,})({endfor})/i' => '<?php for($i=0;$i<${2};$i++) : ?> ${4} <?php endfor; ?' . '>',
    '/({{)(\w+)(}})/i' => '<?php echo $${2}; ?' . '>'
);
$php = file_get_contents('teamplate.php');
foreach ($this->getPatternAndReplacement() as $pattern => $replacement) {
    $php = preg_replace($pattern, $replacement, $php);
}

<小时>

我读过 (...) 捕捉任何东西，但与

---

I've read that (...) catch anything but with

'/({for) (\d+) (times})(...)({endfor})/i'

不起作用 =(.

推荐答案

如果您的字面意思是 (...)，那就是正好匹配三个字符的组.(.+) 将匹配一个或多个任何字符，除了...

If you literally mean (...), that is a group that matches exactly three characters. (.+) would match one or more of any characters, except...

默认情况下，. 匹配任何除了换行符.

By default, . matches anything except newlines.

s (PCRE_DOTALL)
如果设置了此修饰符，则模式中的点元字符将匹配所有字符，包括换行符.没有它，将排除换行符.

s (PCRE_DOTALL)
If this modifier is set, a dot metacharacter in the pattern matches all characters, including newlines. Without it, newlines are excluded.

使用 s 修饰符 允许 . 匹配换行符.

Use the s modifier to allow . to match newline characters.

/your pattern/s

示例(还有此处):

$str = <<<STR
{for 7 times}
    App2
{endfor}
STR;

preg_match('/({for) (\d+) (times})(.+)({endfor})/s', $str, $matchParts);

print_r($matchParts);

OUTPUT:

Array
(
    [0] => {for 7 times}
    App2
{endfor}
    [1] => {for
    [2] => 7
    [3] => times}
    [4] => 
    App2

    [5] => {endfor}
)
