PHP loop over csv - start and end loop at Regex pattern - php

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
}
}
}

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);
}
Edit: Basically, it does the same as Dan Grossmans solution, but shorter ;-)

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;
}
