用PHP和preg_replace拆分并替换事物，而不是爆炸? [英] Split and replace things with PHP and preg_replace instead of explode?
问题描述
我有一个PHP + HTML代码作为包含函数的字符串.我希望将某些函数调用替换为包含的内容.将许多文件放在一起.
I have a PHP + HTML code as a string containing functions. I want some function calls to be replaced with included content. Put together many files to one.
简短示例-之前
<html>
<?php myclass->my_function('one', 'two', 'three'); ?>
<h1>Content in between</h1>
<?php myclass->my_function('1', '2'); ?>
</html>
简短示例-替换内容
<html>
<?php run('one', 'two', 'three'); /* Run does include a file */ ?>
<h1>Content in between</h1>
<?php run('1', '2'); /* Run does include a file */ ?>
</html>`
简短示例-之后
<html>
<?php
/* Start my_function */
echo 'This is the result of my_function one two three';
/* End my_function
?>
<h1>Content in between</h1>
<?php
/* Start my_function */
<?php myclass->my_function('four', 'five', 'six'); ?>
/* End my_function
?>
</html>
请注意，在包含的内容中找到了myclass.结果需要再次解析.
Notice that myclass is found in the included content. The result needs to be parsed again.
简短示例-之后
整个过程再次被解析，并用包含的内容替换了myclass.
The whole this is parsed again and it replaced the myclass with included content.
<html>
<?php
/* Start my_function */
echo 'This is the result of my_function one two three';
/* End my_function */
?>
<h1>Content in between</h1>
<?php
/* Start my_function */
echo 'four five six';
/* End my_function */
?>
</html>
我试图用爆炸来做到这一点，但是事情变得复杂了.替换内容"和之后"这两个步骤可能需要一步完成.
I tried to do this with explode but it went to complex. The two steps "Replacing content" and "After" might need to be done in one move.
将其视为字符串.preg_replace可以解决这个问题吗?怎么样?
Look at it as a string. Can preg_replace solve this? How?
推荐答案
$str = '<html>
<?php myclass->my_function(\'styles\', \'home.css\'); ?>
<p>Some other content</p>
<?php myclass->my_function(1, 2, 3); ?>
</html>';
function jens($matches)
{
$path = '';
$parts = explode(',', $matches[1]);
foreach($parts as $match)
$path .= '/' . str_replace('\'', '', trim($match));
return $path;
}
$replaced = preg_replace_callback('/<\?php myclass->my_function\((.*?)\); \?>/', 'jens', $str);
echo $replaced;
应该做你想做的事.
