Question

在那里我使用文本文件作为数据库，我的文本文件的内容如下....

SRC ---> M ---> 11/22/1995 ---> myPassword ---> 11/29/2013

我想要做的是编写一个php代码，搜索src并返回我使用以下代码搜索文本文件的密码..

<?php
$file = 'Database.txt';
$searchfor = 'src';

// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');

// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
// escape special characters in the query
$pattern = preg_quote($searchfor, '/');
// finalise the regular expression, matching the whole line
$pattern = "/^.*$pattern.*\$/m";
// search, and store all matching occurences in $matches
if(preg_match_all($pattern, $contents, $matches)){
   echo implode("\n", $matches[0]);
}
else{
   echo "No matches found";
}
?>

我怎么能让它回应密码....任何帮助将不胜感激...提前感谢... :)我知道使用文本文件作为数据库是不安全但仍然...

我刚才输入了这段代码：

$strArray = explode(' ---> ',implode($matches[0]));
$name = $strArray[3];
echo "\n" . $name;

后：

if(preg_match_all($pattern, $contents, $matches)){

我从PHP - get certain word from string

获得了一些帮助

php - 文本文件，来自文本文件的echo密码
