從log.txt文件

Question

繼續從Getting the file name from a text file after string matching - PHP 我有格式的log.txt文件讀取錯誤和文件名：

================================================ 
Header of entry with date and time 
================================================ 
Loaded options from XML file: '/path/to/the/file/some_file.xml 
extendedPrintPDF started 
Postfix '4.4' was append from file 'some-other_file.xml' for file: /path/to/the/file/some-other_file.indd 
printPDF started 
PDF Export Preset: Some preset 
PDF file created: '/path/to/the/file/some_filey_namex_lo_4.4.pdf'.

postprocessingDocument started 
INDD file removed: /path/to/the/file/some_file1_name_lo.indd 
Error opening document: /path/to/the/file/some_file_name_lo.indd: Error: Either the file does not exist, you do not have permission, or the file may be in use by another application; line: 190 
================================================ 
Header of entry with date and time 
================================================ 
Loaded options from XML file: '/path/to/she/file/some_options.xml 
extendedPrintPDF started 
extendedPrintPDF: Error: Unsaved documents have no full name.; line: 332 

我想捕字「錯誤」（如果存在）的日誌條目，然後檢測錯誤消息（如「未保存的文件都沒有全名」），或者只是「錯誤打開文件」，並獲得所有和ONLY正在創建的PDF文件的名稱。

我是一個新手，真的不知道應該怎麼去這樣做。

我想我已經提供了完整的信息，這是我沒在我以前的帖子做。

更改： 我還想從/path/to/the/file/filename.something獲取'the'。 我不是在尋找一個確切的答案（儘管這將是巨大的）。但是，一些幫助或指導將不勝感激。

注： 有沒有辦法做到這一點，不許使用正則表達式（我是一個新手，也，我不是在正則表達式都好） 感謝

Answer 1

這確實只匹配有限的日誌的語法片斷你給了我們，但它應該一開始做的。它通過日誌文件運行線由行和會盡力跟蹤哪些過時的部分的它在

<?php 
$logfile = '/path/to/the/file.log'; 
$fh = fopen($logfile, 'r') or die("can't open file."); 

$r_delim = '/^=*$/';   // matches lines of only = 
$r_time = '/^\[(.*)\] - .*$/'; // matches lines that start with [, captures contents between [ and ] 
$r_error = '/ Error: /';  // matches lines that contain the string ' Error: ' 

$skip_delim = FALSE; 
$last_timestamp = 'no stamp'; 
$matches = array(); 

while($line = fgets($fh)) { 
     if(preg_match($r_delim, $line) && ! $skip_delim) { 
       $line = fgets($fh); 
       preg_match($r_time, $line, $matches); 
       $last_timestamp = $matches[1]; 
       $skip_delim = TRUE; 
     } else if(preg_match($r_delim, $line) && $skip_delim) { 
       $skip_delim = FALSE; 
     } else if(preg_match($r_error, $line)) { 
       printf('%s :: %s', $last_timestamp, $line); 
     } 
} 

輸出：

Answer 2

正則表達式

如何獲得文件名：

#(/.*/\w+\.\w{3})# 

如何得到錯誤：

/Error: (.*)/m 

PHP

<?php 

$file_data = __your__file__data__; 

preg_match_all("#(/.*/\w+\.\w{3})#", $file_data, $filenames); 
var_dump($filenames); 

preg_match_all("/Error: (.*)/m", $file_data, $errors); 
var_dump($errors); 

?>
