Exportieren Sie eine MySQL-Tabelle mit PHP-Code in CSV
Ich habe eine SQL-Tabelle namens pvdata, die ich in eine CSV-Datei exportieren möchte.
Aber ich erhalte die folgenden Ergebnisse anstelle der normal aussehenden Tabelle:
<br />
<font size='1'><table class='xdebug-error xe-notice' dir='ltr' border='1'cellspacing='0' cellpadding='1'>

Mein PHP-Code ist:
<?php
$username = "root";
$password = "";
$hostname = "localhost";
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
$selected = mysql_select_db("user data smart grid",$dbhandle)
or die("Could not select Data Base");
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=pvdata.csv");
header("Pragma: no-cache");
header("Expires: 0");
$query = "SELECT * FROM pvdata";
$export = mysql_query ($query ) or die ( "Sql error : " . mysql_error( ) );
$fields = mysql_num_fields ( $export );
for ( $i = 0; $i < $fields; $i++ )
{
$header .= mysql_field_name( $export , $i ) . "\t";
echo $header;
}
while( $row = mysql_fetch_row( $export ) )
{
$line = '';
foreach( $row as $value )
{
if ( ( !isset( $value ) ) || ( $value == "" ) )
{
$value = "\t";
}
else
{
$value = str_replace( '"' , '""' , $value );
$value = '"' . $value . '"' . "\t";
}
$line .= $value;
}
$data .= trim( $line ) . "\n";
}
$data = str_replace( "\r" , "" , $data );
if ( $data == "" )
{
$data = "\n(0) Records Found!\n";
}
print "$header\n$data";
exit();
?>
Also, was läuft falsch? Wenn ich die Tabelle manuell aus dem phpmyadmin exportiere, funktioniert es einwandfrei. Ich möchte auch die Namen der Spalten in der Tabelle erhalten, wenn möglich.
