how to create html table in php

Question

I have the following snippet of code that basically uses explode to split out these values:

<?php
$data=array();
$Inputfile = file("prod.txt");
foreach ($Inputfile as $line){
   $pieces = explode(";", $line);
   echo $pieces[0];
   echo $pieces[1];
   echo $pieces[2];
   echo $pieces[3];
//print_r($line);
}
?>

Data: (prod.txt)

PREFIX=abc;PART=null;FILE=/myprojects/school/out/data/feed_abc_2010120810.gz2
PREFIX=efg;PART=sdsu;FILE=mail_efg.dat.2010120810.gz2

Can someone show me how to put this in an HTML table dynamically, like this?? Is there an easy way to do this? Thanks.

PREFIX  PART   FILE
abc     null   /myprojects/school/out/data/feed_abc_2010120810.gz2
efg     sdsu   mail_efg.dat.2010120810.gz2

The Clean Way

<?php
$inputfile = file("prod.txt");

$data_lines = array();
foreach ($inputfile as $line)
{
    $data_lines[] = explode(";", $line);
}

//Get column headers.
$first_line = array();
foreach ($data_lines[0] as $dl)
{
    $first_line[] = explode("=", $dl);
}
$headers = array();
foreach ($first_line as $fl)
{
    $headers[] = $fl[0];
}

// Get row content.
$data_cells = array();
for ($i = 0; $i < count($data_lines); $i++)
{
    $data_cell = array();
    for ($j = 0; $j < count($headers); $j++)
    {
        $data_cell[$j] = substr($data_lines[$i][$j], strpos($data_lines[$i][$j], "=")+1);
    }
    $data_cells[$i] = $data_cell;
    unset($data_cell);
}
?>

@cjd143SD, it should work perfectly now. It takes the presence of "PREFIX=" etc. into account and should work for any number of rows and columns.

This should be flexible enough and won't require any hard-coded pair names:

<?php

$lines = preg_split('~\s*[\r\n]+\s*~', file_get_contents('prod.txt'));

foreach($lines as $i => $line) {
    $pairs = explode(';', $line);
    foreach($pairs as $pair) {
        list($column, $value) = explode('=', $pair, 2);
        $columns[$column] = true;
        $rows[$i][$column] = $value;
    }
}

$columns = array_keys($columns);


echo '<table><thead><tr>';

foreach($columns as $column) {
    echo '<th>'.$column.'</th>';
}

echo '</tr></thead><tbody>';

foreach($rows as $row) {
    echo '<tr>';
    foreach($columns as $column) {
        echo '<td>'.$row[$column].'</td>';
    }
    echo '</tr>';
}
echo '</tbody></table>';

?>

thanks. works great. good example of using preg_split. new for me. ;-)

No problem. file() can take care of empty lines, too, but using this method has the added benefit of trimming whitespace.

echo '<table><tr><td>PREFIX</td><td>Part</td>File</td></tr>';
foreach ($Inputfile as $line){
   $pieces = explode(";", $line);
   $count=count($pieces);

   echo '<tr>';
   for ($counter=0; $counter <$count; $counter++)
   {
     echo '<td>'.$pieces[$counter].'<td>';
   } 
  echo '</tr>';
}

Not the prettiest solution, just an example:

echo '<table><tr><td>PREFIX</td><td>PART</td><td>FILE</td></tr>';
foreach ($Inputfile as $line)
{
    $pieces = explode(';', $line);
    echo sprintf(
        '<tr><td>%s</td><td>%s</td><td>%s</td></tr>',
        ltrim($pieces[0], 'PREFIX='),
        ltrim($pieces[1], 'PART='),
        ltrim($pieces[2], 'FILE=')
    );
}
echo '</table>';

You've really got two problems here:

1) Parsing the information in each line into a record / associative array

2) Representing the series of these records/arrays as an HTML table.

Good code will separate these concerns somewhat.

function line2record($line) {
   $recordAA = array();
   $keyValuePairs = explode(';',$line);
   foreach($keyValuePairs as $kvp) {
       $pieces = explode('=',$kvp);
       $recordAA[$pieces[0]] = $pieces[1];
   }
   return $recordAA;
}

function record2TR($recordAA) {
   $str = implode('</td><td>',$recordAA);
   return "<tr><td>$str</td></tr>";
}

After that, it's pretty much a matter of applying these two functions to each line of the file:

$Inputfile = file("prod.txt");
foreach ($Inputfile as $line)
    echo record2TR(line2record($line));

To get the header row, and the table/open close markup, you might do something like this:

function record2TH($recordAA) {
    $headers = array_keys($recordAA);
    $str = implode('</th><th>',$headers);
    return "<tr><th>$str</th></tr>";
}

and then:

$fp = fopen('prod.txt','r');
$line = fgets($fp,MAX_LINE_LENGTH);  // you'd set this constant
$firstRecord = line2record($line);
echo "<table>";
echo record2TH($firstRecord);
echo record2TR($firstRecord);
while($line = fgets($fp,MAX_LINE_LENGTH))
    echo record2TR(line2record($line));
echo "</table>";

This was my approach

echo '<table id="time-table" border="2"><thead><tr >';
echo '<th style="width:40%; padding: 7px;">Course Code</th>';
echo '<th style="width:30%">Course Name</th>';
echo '<th style="width:40%">Slot</th>';
for ($x = 0; $x < 5; $x++) {
   echo '<tr id=row'.$x.'>';
   echo '<th style="width:40%; padding: 15px;" >',$xml_data->children()[$x]->coursecode .'</th>';
   echo '<th style="width:30%">',$xml_data->children()[$x]->coursename .'</th>';
   echo '<th style="width:20%">',$xml_data->children()[$x]->slot .'</th>';
 }
echo '</tbody></table>';
