PHP简单模板引擎/函数
我需要创建一个简单的模板引擎；我不能使用Twig或Smarty等，因为项目中的设计师需要能够将她的HTML复制/粘贴到模板中，而无需任何配置、混乱或混乱。这一定很容易 因此，我创建了一些东西，通过将她的内容放在PHP简单模板引擎/函数,php,templates,preg-replace,Php,Templates,Preg Replace,我需要创建一个简单的模板引擎；我不能使用Twig或Smarty等，因为项目中的设计师需要能够将她的HTML复制/粘贴到模板中，而无需任何配置、混乱或混乱。这一定很容易 因此，我创建了一些东西，通过将她的内容放在{{{content}}{{content}}标记之间，让她能够做到这一点 我唯一的问题是，我想确保如果她在标签中使用了多个空格——或者没有空格——它不会中断；i、 e.{{CONTENT}或{{{CONTENT}} 我在下面所做的就是实现这一点，但我担心这可能是矫枉过正。有人知道简化这个
{{{content}}{{content}}{{CONTENT}{{{CONTENT}}function defineContent($tag, $string) {
$offset = strlen($tag) + 6;
// add a space to our tags if none exist
$string = str_replace('{{'.$tag, '{{ '.$tag, $string);
$string = str_replace($tag.'}}', $tag.' }}', $string);
// strip consecutive spaces
$string = preg_replace('/\s+/', ' ', $string);
// now that extra spaces have been stripped, we're left with this
// {{ CONTENT }} My content goes here {{ !CONTENT }}
// remove the template tags
$return = substr($string, strpos($string, '{{ '.$tag.' }}') + $offset);
$return = substr($return, 0, strpos($return, '{{ !'.$tag.' }}'));
return $return;
}
// here's the string
$string = '{{ CONTENT }} My content goes here {{ !CONTENT }}';
// run it through the function
$content = defineContent('CONTENT', $string);
echo $content;
// gives us this...
My content goes here
我建议查看模板范围内的变量提取。 与替换方法相比，它更易于维护，开销更小，而且通常更易于设计者使用。在它的基本形式中，它只是PHP变量和短标记 它取决于您生成的哪一侧，例如表及其行（或完整的内容块）-它可能只是
src/Templates/Article.php<html>
<body>
<h1><?=$title?></h1>
<div><?=$content?></div>
</body>
</html>
...
// initalize
$view = new View;
// assign
$view->data['title'] = 'The title';
$view->data['content'] = 'The body';
// render
$view->render(dirname(__DIR__) . '/Templates/Article.php');
class View
{
/**

public $data = [];

function render($template)
{
if (!is_file($template)) {
throw new \RuntimeException('Template not found: ' . $template);
}
// define a closure with a scope for the variable extraction
$result = function($file, array $data = array()) {

具体回答您的问题： 我唯一的问题是，我想确保如果她在标记中使用多个空格，或者没有空格，它不会中断 我在下面所做的就是实现这一点，但我担心这可能是矫枉过正。有人知道简化这个函数的方法吗
function defineContent($tag, $string) {
$offset = strlen($tag) + 6;
// add a space to our tags if none exist
$string = str_replace('{{'.$tag, '{{ '.$tag, $string);
$string = str_replace($tag.'}}', $tag.' }}', $string);
// strip consecutive spaces
$string = preg_replace('/\s+/', ' ', $string);
// now that extra spaces have been stripped, we're left with this
// {{ CONTENT }} My content goes here {{ !CONTENT }}
// remove the template tags
$return = substr($string, strpos($string, '{{ '.$tag.' }}') + $offset);
$return = substr($return, 0, strpos($return, '{{ !'.$tag.' }}'));
return $return;
}
// here's the string
$string = '{{ CONTENT }} My content goes here {{ !CONTENT }}';
// run it through the function
$content = defineContent('CONTENT', $string);
echo $content;
// gives us this...
My content goes here
。。。功能中唯一“慢”的部分是
preg\u replacefunction defineContent($tag, $string) {
$offset = strlen($tag) + 6;
// add a space to our tags if none exist
$string = str_replace('{{'.$tag, '{{ '.$tag, $string);
$string = str_replace($tag.'}}', $tag.' }}', $string);
// strip consecutive spaces
