PHP遍歷CSV - 啓動和正則表達式的結束循環

Question

我需要打印出csv文件轉換成HTML或者把數字數據存入數據庫：
但我需要在特定位置，開始一個循環，並在另一個特定打破它位置（正則表達式）。
所以我需要重印只有行數字數據和他們的所有列。
以下是僞碼 - 不能正常工作：

<?php 
$row = 1; 
$handle = fopen("test.csv", "r"); 
while ($data = fgetcsv($handle, 1000, ",")) 
{ 
    if (preg_match('/[Morning]/', $data[0]) === 1 // start at this rwo plus two lines down) 
    { 
    $num = count($data); 
    $row++; 
     for ($c=0; $c < $num; $c++) 
     { 
      for ($c=0; $c < $num; $c++) 
      { 
       echo $data[$c] . " "; 
      } 
     if (preg_match('/[Total Cash:]/', $data[0]) === 1) 
     { break; row -1 }    
     } 
     echo "<br>"; 
    } 
} 
fclose($handle); ?> 

因此CSV是這樣的：

 
/--some lines--/
 

Date: 3/3/11, 
Morning, 
--blank line--- 
Customer No,Time,CheckNo,Total, 
1234,12-45,01,20.00, 
1236,1-00,03,30.00, 
1240,2-00,06,30.00, 
--more numerical rows of data at variable length that I need to loop over-- 
1500,4-00,07,22.00, 
----,----,---,----, 
Total Cash, , , ,120.00,
 

/--some other lines--and it goes/
 

Lunch Time, 
---similar like Morning above --- 

任何信息如何正確addrres這一問題表示讚賞，我現在可以做這麼多的循環和正則表達式但有了這個，我需要更多的時間和幫助。謝謝。

Answer 1

$lines = file('test.csv'); //read file into an array, one entry per line 

$active = false; //keep track of what rows to parse 

//loop one line at a time 
for ($i = 0; $i < count($lines); $i++) { 
    $line = $lines[$i]; 

    if (strpos($line, 'Morning') !== false) { //start parsing on the next row 
    $active = true; 
    $i += 2; //skip the blank line and header 
    continue; 
    } 
    if (strpos($line, '----,') !== false) { //stop parsing rows 
    $active = false; 
    } 

    if ($active) { //if parsing enabled, split the line on commas and do something with the values 
    $values = str_getcsv(trim($line)); 
    foreach ($values as $value) { 
     echo $value . " "; //these are the numbers 
    } 
    } 

} 

Answer 2

$lines = file('test.csv'); 
$parsing = false; 
foreach ($lines as $line) 
{ 
    $parsing = ((strpos($line, 'Morning') !== false) || $parsing) 
     && ((strpos($line, 'Total Cash') === false); 

    if (!$parsing) 
     continue; 

    $values = strgetcsv($line); 
    echo implode(' ', $values); 
} 

編輯：基本上，它同樣丹Grossmans的解決方案，但較短的;-)

Answer 3

$lines = file('test.csv'); 

// Skip the unwanted lines 
// Means: Every line until the line containing "Morning," 
do { 
    $line = array_shift($lines); 
} while(trim($line) !== 'Morning,'); 
$lines = array_slice($lines, 2); // Mentioned something about "2 lines below" or such" ^^ 

// Do something with the remaining lines, until 
// Line _begins_ with "Total Cash" 
while(strncmp('Total Cash', trim($line = array_shift($lines)), 10) !== 0) { 
    echo implode(' ', str_getcsv($line)) . PHP_EOL; 
}
