Php - Array to string conversion - php

Question

I want to output all records in my database. So far so good, but when I loop through it, php gives me an error " Array to string conversion ".
I added an index to the array but then it does just output obviously the first or secound ( etc. ) column.
$conn = new PDO("mysql:host=localhost;dbname=database","root","");
$stmt = $conn->prepare('SELECT * FROM de');
$stmt ->execute();
$result = $stmt ->fetchAll();
if (is_array($result) || is_object($result))
{
foreach ($result[0] as $value)
{
echo "<table><tr><td>'$value'</td></tr></table>";
}
}
So, with the index, it does work. But I need all records, not just one.
I appreciate every comment and help!

Answer 1

I would start with a nested loop. I also wonder if you want a table for every value
$conn = new PDO("mysql:host=localhost;dbname=database","root","");
$stmt = $conn->prepare('SELECT * FROM de');
$stmt ->execute();
$result = $stmt ->fetchAll();
if (is_array($result) || is_object($result))
{
foreach ($result as $row){ //Go through every row in the result
echo('<table>');
foreach ($row as $value){ //Go through every value in the row
echo "<tr><td>'$value'</td></tr>";
}
echo('</table>');
}
}
This will print every row as a new table, but you can search out the variation you want.

Answer 2

A nested foreach loop should work.
foreach ($result as $values)
{
foreach ($values as $value) {
echo "<table><tr><td>'$value'</td></tr></table>";
}
}

Answer 3

An alternative to nested loops, if you know the number of fields and said number is constant for each execution; A state that's found in most situations; You can use vsprintf () to print out the rows.
Quick example:
$result = {{'John', 'Doe'}, {'Sarah', 'Jane'}};
$output = '<table>';
foreach ($result as $row) {
$output .= vsprintf ("<tr><td>%s</td><td>%s</td></tr>\n", $row);
}
echo $output."</table>";
Cuts down a bit on the code, and quite a bit on the code complexity. The template for the rows themselves can also be extracted to a variable (or template view), outside of the loop, to make the code even cleaner.
