Parsing data into HTML tables and categories - php

Question

I am to import a file, say june.txt that would have data such as the following data:
Sandy,820,384,133,18,408
Wanda,120,437,128,807,595
Jane,631,415,142,687,600
Andrea,179,339,349,594,986
Wanda,803,191,6,807,322
Jane,741,975,34,15,832
Jane,239,714,250,94,497
Andrea,219,188,411,584,713
And then the PHP would parse it into 2 difference ways:
The first way being all the names bundled together with totals, such as:
Sandy 820 384 133 18 408
Total 820 384 133 18 408
Jane 631 415 142 687 600
Jane 741 975 34 15 832
Jane 239 714 250 94 497
Total 1611 2104 426 796 497
Andrea 179 339 349 594 986
Andrea 219 188 411 584 713
Total 398 527 760 1178 1699
Wanda 120 437 128 807 595
Wanda 803 191 6 807 322
Total 923 628 134 1614 917
The second way would total and add the names together in a big list, such as
Sandy 820 384 133 18 408
Jane 1611 2104 426 796 497
Andrea 398 527 760 1178 1699
Wanda 923 628 134 1614 917
Any logic or suggestions would be helpful, I am new to PHP and not sure how this could even be done. My plan is to eventually display the results in HTML tables and have them sortable, but I can tackle that at a later date, Unless someone feels obligated to just add the and such for me in the parsing.

Answer 1

I think something useful for you would be the explode function.
As far as creating these views I'd start by loading all this data into an associative array of arrays based on the name, then iterate as necessary:
$datafile = file("filename.txt");
// reads lines into an associative array (key is the name) of arrays
// where each sub-array is a list of the records for each name
$arr = array();
foreach($datafile as $line){
$temp = explode(',', $line);
$arr[$temp[0]][] = $temp;
}
// iterate over each person
foreach($arr as $person_set){
// create an array to hold the sum of each column
// (and the name in the first column)
$totals = array();
$totals[0] = $person_set[0][0];
for($i = 1; $i < length($record); $i++){
$totals[$i] = 0;
}
// now iterate over each record for this person
foreach($person_set as $record){
// print a particular record
echo implode(' ', $record) . '<br>';
// add each column (1..end) to the totals array
for($i = 1; $i < length($record); $i++){
$totals[$i] += $record[$i];
}
}
// print out the totals line
echo implode(' ', $totals) . '<br><br>';
}
I'll leave formatting this data into a table as an exercise.

Answer 2

Well, to start, I'd real a file like that with PHP's fgetcsv(). Docs.

Answer 3

You could try a script like this:
<?php
echo "<table>";
$data = file("june.txt");
foreach($data as $month) {
$line = explode(',', $data);
echo '<tr><td>', implode('</td><td>', $line), '</td></tr>';
}
echo "</table>";
Edit:
My bad, didn't notice that you were sorting/grouping/totaling. This should set you on the right track, though. The key is to use $line as your source of information. Just compile it into an array and output later (instead of right in the loop).
