中文提供PHP preg_match_all

Question

我有一箇中文提供導出的文本文件。 該文本文件具有以下模式的許多條目。

@article{ls_leimeister, 
    added-at = {2013-01-18T11:14:11.000+0100}, 
    author = {Wegener, R. and Leimeister, J. M.}, 
    biburl = {http://www.bibsonomy.org/bibtex/27bb26b4b4858439f81aa0ec777944ac5/ls_leimeister}, 
    journal = {International Journal of Technology Enhanced Learning (to appear)}, 
    keywords = {Challenges Communities: Factors Learning Success VirtualCommunity and itegpub pub_jml pub_rwe}, 
    note = {JML_390}, 
    title = {Virtual Learning Communities: Success Factors and Challenges}, 
    year = 2013 
} 

我想使用PHP和preg_match_all

考慮下面沒得到我的任何地方：

preg_match_all('/@^.*}$/', file_get_contents($file_path),$results); 

我想開始簡單的，但真正地沒有工作。 我有點新的PHP RegEx。

完美的最終輸出將是：

Array 
    (
     [0] => Array 
      (
       ['type'] => article 
       ['unique_name'] => ls_leimeister 
       ['added-at'] => 2013-01-18T11:14:11.000+0100 
       ['author'] => Wegener, R. and Leimeister, J. M. 
       ['biburl'] => http://www.bibsonomy.org/bibtex/27bb26b4b4858439f81aa0ec777944ac5/ls_leimeister 
       ['journal'] => International Journal of Technology Enhanced Learning (to appear) 
       ['keywords'] => Challenges Communities: Factors Learning Success VirtualCommunity and itegpub pub_jml pub_rwe 
       ['note'] => JML_390 
       ['title'] => Virtual Learning Communities: Success Factors and Challenges 
       ['year'] => 2013 
      ) 

     [1] => Array 
      (
       [...] => … 
      ) 

    ) 

Answer 1

試試這個：這裏我只進賬和typeunique_name，通過觀察它，你可以獲取所有其他人。

$str = '@article{ls_leimeister, 
    added-at = {2013-01-18T11:14:11.000+0100}, 
    author = {Wegener, R. and Leimeister, J. M.}, 
    biburl = {http://www.bibsonomy.org/bibtex/27bb26b4b4858439f81aa0ec777944ac5/ls_leimeister}, 
    journal = {International Journal of Technology Enhanced Learning (to appear)}, 
    keywords = {Challenges Communities: Factors Learning Success VirtualCommunity and itegpub pub_jml pub_rwe}, 
    note = {JML_390}, 
    title = {Virtual Learning Communities: Success Factors and Challenges}, 
    year = 2013 
}'; 

preg_match_all('/@(?P<type>\w+){(?P<unique_name>\w+),(.*)/',$str,$matches); 

echo $matches['type'][0]; 
echo "<br>"; 
echo $matches['unique_name'][0]; 
echo "<br>"; 

echo "<pre>"; 
print_r($matches); 

輸出數組格式與您的輸出數組格式稍有不同，但您可以將此格式更改爲您的格式。

Answer 2

圖樣：/^@([^{]+)\{([^,]+),\s*$|^\s*([^\R@=]+) = \{(.*?)}/ms（Demo）

這種模式有兩個替代方案;每個包含兩個捕獲組。

• type和unique_name被捕獲並存儲在元件[1]和[2]。
• 所有其他鍵 - 值對存儲在元素[3]和[4]。

此分離的陣列存儲允許可靠的加工構建所期望的輸出陣列結構時。

輸入：

$bibtex='@BOOK{ko, 
    title = {Wissenschaftlich schreiben leicht gemacht}, 
    publisher = {Haupt}, 
    year = {2011}, 
    author = {Kornmeier, M.}, 
    number = {3154}, 
    series = {UTB}, 
    address = {Bern}, 
    edition = {4}, 
    subtitle = {für Bachelor, Master und Dissertation} 
} 

@BOOK{nial, 
    title = {Wissenschaftliche Arbeiten schreiben mit Word 2010}, 
    publisher = {Addison Wesley}, 
    year = {2011}, 
    author = {Nicol, N. and Albrecht, R.}, 
    address = {München}, 
    edition = {7} 
} 

@ARTICLE{shome, 
    author = {Scholz, S. and Menzl, S.}, 
    title = {Alle Wege führen nach Rom}, 
    journal = {Medizin Produkte Journal}, 
    year = {2011}, 
    volume = {18}, 
    pages = {243-254}, 
    subtitle = {ein Vergleich der regulatorischen Anforderungen und Medizinprodukte 
    in Europa und den USA}, 
    issue = {4} 
} 

@INBOOK{shu, 
    author = {Schulz, C.}, 
    title = {Corporate Finance für den Mittelstand}, 
    booktitle = {Praxishandbuch Firmenkundengeschäft}, 
    year = {2010}, 
    editor = {Hilse, J. and Netzel, W and Simmert, D.B.}, 
    booksubtitle = {Geschäftsfelder Risikomanagement Marketing}, 
    publisher = {Gabler}, 
    pages = {97-107}, 
    location = {Wiesbaden} 
}'; 

方法：（Demo）

$pattern='/^@([^{]+)\{([^,]+),\s*$|^\s*([^\R@=]+) = \{(.*?)}/ms'; 
if(preg_match_all($pattern,$bibtex,$out,PREG_SET_ORDER)){ 
    foreach($out as $line){ 
     if(isset($line[1])){ 
      if(!isset($line[3])){ // this is the starting line of a new set 
       if(isset($temp)){ 
        $result[]=$temp; // send $temp data to permanent storage 
       } 
       $temp=['type'=>$line[1],'unique_name'=>$line[2]]; // declare fresh new $temp 
      }else{ 
       $temp[$line[3]]=$line[4]; // continue to store the $temp data 
      } 
     } 
    } 
    $result[]=$temp; // store the final $temp data 
} 
var_export($result); 

輸出：

    'type' => 'BOOK', 
    'unique_name' => 'ko', 
    'title' => 'Wissenschaftlich schreiben leicht gemacht',

這裏是the site我提取新的採樣輸入的字符串從。
