Question

I need to print out csv file into html or put a numeric data into database:
But I need to start a loop at specific position and break it at another specific position (regex).
So I need to reprint only rows with numerical data and all columns from them.
Following is pseudo-code – not working properly:

<?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); ?>

So csv goes like this:

/--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 ---

Any info how to properly addrres this issue is appreciated, I can now do so many loops and regex but with this I need some more time and help. Thanks.

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
    }
  }
