How can I generate output from a PHP script in a tabular format
Her开发者_如何学Pythone is an example with columns and values:
+----------------------------------------------------------------+ | rate | conn/s | req/s | replies/s avg | errors | net io (KB/s) | +----------------------------------------------------------------+ | 100 | 99.9 | 99.9 | 99.7 | 0 | 45.4 | | 120 | 119.7 | 119.7 | 120.0 | 0 | 54.4 | | 140 | 139.3 | 139.3 | 138.0 | 0 | 63.6 | |> 160 | 151.9 | 151.9 | 147.0 | 0 | 69.3 | | 180 | 132.2 | 129.8 | 137.4 | 27 | 59.6 | | 200 | 119.8 | 117.6 | 139.9 | 31 | 53.9 | +----------------------------------------------------------------+
Assuming that you want to display it in a browser and fetching data from MySQL. Use this code, replace your dbname and tablename with correct values:
<html>
<head><title>Result as Table</title></head>
<body>
<?php
$db_host = 'localhost';
$db_user = 'root';
$db_pwd = '';
$database = 'dbname';
$table = 'tablename';
if (!mysql_connect($db_host, $db_user, $db_pwd))
die("Can't connect to database");
if (!mysql_select_db($database))
die("Can't select database");
// sending query
$result = mysql_query("SELECT * FROM {$table}");
if (!$result) {
die("Query to show fields from table failed");
}
$fields_num = mysql_num_fields($result);
echo "<h1>Table: {$table}</h1>";
echo "<table border='1'><tr>";
// printing table headers
for($i=0; $i<$fields_num; $i++)
{
$field = mysql_fetch_field($result);
echo "<td>{$field->name}</td>";
}
echo "</tr>\n";
// printing table rows
while($row = mysql_fetch_row($result))
{
echo "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</td>";
echo "</tr>\n";
}
mysql_free_result($result);
?>
</body></html>
Look into printf/sprintf:
printf('| %3s | %-5.1f | …', $rate, $conns, …);
printf() is your friend here.
<?php
function printRows($rows){
$br = "+----------------------------------------------------------------+";
$he = "| rate | conn/s | req/s | replies/s avg | errors | net io (KB/s) |";
//Print out the header
print "$br\n$he\n$br\n";
//Iterate through the rows
foreach($rows as $row){
printf("|[%-5s] | [%-7s] | [%-5s] | [%-13s] | [%-6s] | [%-13s] |",
$row[0],$row[1],$row[2],$row[3],$row[4],$row[5]
);
}
//Print the end ascii-art
print "$br\n";
}
?>
