PHP在多个自定义标签之间获取文本

Question

I need to parse a custom template file.

Lets say my template file looks like this.

@section('section1')
    some content
@endsection

@section('section2')
    some more content
@endsection

As a result of the parsing i need the following result:

array(
    'section1' => 'some content',
    'section2' => 'some more content'
);

I tried to get the section names first with this code:

$sectionPattern = '/(?<=\@section\().*?(?=\))/';
preg_match_all($sectionPattern, $this->fileContents, $sections);

which works as expected. The result looks like:

$sections = array(
    array(
        0 => 'section1',
        1 => 'section2'
    )
);

If i try to get the content for each section with this code:

foreach($sections[0] as $section) {
    $contentPattern = '/(?<=\@section\(' . $section . '\)).*?(?=@endsection)/';
    preg_match_all($contentPattern, $this->fileContents, $content);
    echo '<pre>';
    print_r($content);
}

i only get empty arrays and i cant figure out why.

Also, if you anyone sees a more elegant way to get the desired result. I'm open for suggestions.

Thanks in advance.

You can get both matches in one pattern and then combine them. You don't show the content being multi-line but this will handle it. The array_map('trim', $sections[2]) gets rid on the whitespace/newlines at either end of the content:

preg_match_all("/@section\('([^']+)'\)([^@]+)/", $this->fileContents, $sections);
$sections = array_combine($sections[1], array_map('trim', $sections[2]));
