Export a mysql table into CSV using PHP code

Question

I have a my sql table called pvdata, I would like to export it to csv file.

But I\'m obtaining the following results instead of the normal looking table:

Answer 1

Before for loop initialize $header to empty string.

$header = '';//initialize header
for ( $i = 0; $i < $fields; $i++ )
{
    $header .= mysql_field_name( $export , $i ) . "\t";

    echo $header;//remove this line
}

EDIT

Also initialize $data outside while loop.

$data = '';
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";
}

Answer 2

Try this code -

<?php

    // Database Connection

    $host="localhost";
    $uname="root";
    $pass="";
    $database = "a2zwebhelp"; 

    $connection=mysql_connect($host,$uname,$pass); 

    echo mysql_error();

    //or die("Database Connection Failed");
    $selectdb=mysql_select_db($database) or 
    die("Database could not be selected"); 
    $result=mysql_select_db($database)
    or die("database cannot be selected <br>");

    // Fetch Record from Database

    $output = "";
    $table = ""; // Enter Your Table Name 
    $sql = mysql_query("select * from $table");
    $columns_total = mysql_num_fields($sql);

    // Get The Field Name

    for ($i = 0; $i < $columns_total; $i++) {
    $heading = mysql_field_name($sql, $i);
    $output .= '"'.$heading.'",';
    }
    $output .="\n";

    // Get Records from the table

    while ($row = mysql_fetch_array($sql)) {
    for ($i = 0; $i < $columns_total; $i++) {
    $output .='"'.$row["$i"].'",';
    }
    $output .="\n";
    }

    // Download the file

    $filename = time().'csv'; //For unique file name
    header('Content-type: application/csv');
    header('Content-Disposition: attachment; filename='.$filename);

    echo $output;
    exit;

    ?>

Answer 3

I don't know if it is a typo, but within your script are spaces before the

   <?php

this will result in an html document being delivered and your header-calls will fail. So remove the spaces and any other output before "header" calls.

You are getting error messages up there, for a quick solution try:

error_reporting(0);

Line 28: $header is not known, this makes

$header .=

appending to a unknown variable.

You can use fputcsv function for clear code.
