如何使用PHP取消for循环中的元素范围？ [英] How to uncapture the range of elements in for loop using PHP?

问题描述

示例：



@article {boonzaier2009development，

author =Boonzaier，A。和Schubach，K。和Troup，K和Pollard，A。和Aranda，S。和Schofield，P。，

title =心理教育干预的发展，

journal =心理社会杂志肿瘤科，

体积=27，

数=1，

pages =136-153，
year = 2009

}



@book {bottoff2008women，

author =Bottoff ，JL和Oliffe，JL和Halpin，M。和Phillips，M。和McLean，G。和Mroz，L。，

title =妇女和前列腺癌支持团体：{The}性别connect？{Social} {Science}& {Medicine}，

publisher =66，

pages =1217-1227，

年= 2008

}



@article {bottorff2012gender，

author =Bottorff，JL和Oliffe，JL和Kelly，M。，

title =r中的性别oom，

journal =定性健康研究，

volume =22，

number =4，
pages =435-440，

year = 2012

}

我想捕获双引号之间的字符串仅@article部分。我得到@article的数量和@article字段的范围来获取@article元素的值。使用for循环获取@article的值（对于循环值：@article到next @article的范围等等）问题是，例如第一个字符串@article在第10行，第二个在第18行，am在这个范围和获取值之间进行循环，但是，介于@book之间也是如此，以便如何消除for循环中的@book范围。因为它捕获了@book元素，因为它位于@article的范围内。



php代码：

 <？php  
 $ file = file（  master.bib）; 
 $ typeart = array（）; 
 $ cont = array（）; 
 
  //  文章数量 
  $ key  = '  @ article'; 
  foreach （$ file  as   $ l  => $ line）{
  if （strpos（$ line，$ key）！== false）{
 $ l ++ ; 
 $ typeart [] =  $ l ; 
 
} 
}  //  文章的最终数量 
 
 $ counttypeart = count（$ typeart）; 
 
 for（$ j = 0; $ j< $ counttypeart; $ j ++）{
 
 for（$ i = $ typeart [$ j]; $ i< $ typeart [$ j + 1]; $ i ++）{
 if（strpos（$ file [$ i]，' 作者'））{
 preg_match（'  / \（。*？） \/，$文件[$ i]于，$续）; 
 $ author = $ cont [1]; 
  echo   $ author ; 
  echo ; 
} 
 if（strpos（$ file [$ i]，'  title'））{
 preg_match（'  / \（。*？）\/'< /跨度>，$文件[$ i]于，$续）; 
 $ title = $ cont [1]; 
  echo   $ title ; 
  echo ; 
} 
 if（strpos（$ file [$ i]，'  journal'））{
 preg_match（'  / \（。*？）\/'< /跨度>，$文件[$ i]于，$续）; 
 $ journal = $ cont [1]; 
  echo   $ journal ; 
  echo ; 
} 
 
 if（strpos（$ file [$ i]，'  volume '））{
 preg_match（'  / \（。*？）\ /，$文件[$ i]于，$续）; 
 $ volume = $ cont [1]; 
  echo   $ volume ; 
  echo ; 
} 
 
 if（strpos（$ file [$ i]，'  number '））{
 preg_match（'  / \（。*？）\ /，$文件[$ i]于，$续）; 
 $ number = $ cont [1]; 
  echo   $ number ; 
  echo ; 
} 
 
 if（strpos（$ file [$ i]，'  pages '））{
 preg_match（'  / \（。*？）\ /，$文件[$ i]于，$续）; 
 $ pages = $ cont [1]; 
  echo   $ pages ; 
  echo ; 
  echo ; 
} 
} 
}

file = file（ master.bib）;

typeart = array（）;

CONT =阵列（）;

// 文章数量

Example:

@article{boonzaier2009development,
author = "Boonzaier, A. and Schubach, K. and Troup, K. and Pollard, A. and Aranda, S. and Schofield, P.",
title = "Development of a psychoeducational intervention ",
journal = "Journal of Psychosocial Oncology",
volume = "27",
number = "1",
pages = "136-153",

@book{bottoff2008women,

title = "Women and prostate cancer support groups: {The} gender connect? {Social} {Science} & {Medicine}",

I want to capture the string between double quotes of @article part only. Am getting the count of @article and range of @article fields to get the values of @article elements. Using for loop am getting values of @article (for loop values: range of @article to next @article and so on) The problem is, for example first string @article is in 10th line and second one is in 18 th line, am doing for loop between this range and getting the value but, inbetween @book also is there so how to eliminate that @book range of lines in for loop. Because it captures @book elements also as it is inside in the range of @article.

php code:

<?php
$file=file("master.bib");
$typeart=array();
$cont=array();

//count of article
$key = '@article';
foreach ($file as $l => $line) {
    if (strpos($line,$key) !== false) {
       $l++;
       $typeart[]= $l;

          }
}//end-count of article

$counttypeart=count($typeart);

for($j=0;$j<$counttypeart;$j++){

    for($i=$typeart[$j];$i<$typeart[$j+1];$i++){
if(strpos($file[$i],'author')){
preg_match('/\"(.*?)\"/',$file[$i],$cont);
$author= $cont[1];
echo $author;
echo ;
}
if(strpos($file[$i],'title')){
preg_match('/\"(.*?)\"/',$file[$i],$cont);
$title= $cont[1];
echo $title;
echo ;
}
if(strpos($file[$i],'journal')){
preg_match('/\"(.*?)\"/',$file[$i],$cont);
$journal= $cont[1];
echo $journal;
echo ;
}

if(strpos($file[$i],'volume')){
preg_match('/\"(.*?)\"/',$file[$i],$cont);
$volume= $cont[1];
echo $volume;
echo ;
}

if(strpos($file[$i],'number')){
preg_match('/\"(.*?)\"/',$file[$i],$cont);
$number= $cont[1];
echo $number;
echo ;
}

if(strpos($file[$i],'pages')){
preg_match('/\"(.*?)\"/',$file[$i],$cont);
$pages= $cont[1];
echo $pages;
echo ;
echo ;
}
}
}

?>

Expected output (From above mentioned example):

Boonzaier, A. and Schubach, K. and Troup, K. and Pollard, A. and Aranda, S. and Schofield P.

解决方案

file=file("master.bib");

typeart=array();

cont=array(); //count of article
