hola, tengo este script con el que quiero exportar una tabla de mi base de datos, a un archivo CSV.
Código PHP:
<?php
include("db.php"); // archivo de conexión a base de datos
require 'exportcsv.inc.php';
$table="Mi_TABLA"; // this is the tablename that you want to export to csv from mysql.
exportMysqlToCsv($table);
?>
Y este es el archvo exportcsv.inc.php
Código PHP:
<?php
function exportMysqlToCsv($table,$filename = "photo_order_report.csv")
{
$csv_terminated = "\n";
$csv_separator = ",";
$csv_enclosed = '"';
$csv_escaped = "\\";
$sql_query = "select * from $table";
// Gets the data from the database
$result = mysql_query($sql_query);
$fields_cnt = mysql_num_fields($result);
$schema_insert = '';
for ($i = 0; $i < $fields_cnt; $i++)
{
$l = $csv_enclosed . str_replace($csv_enclosed, $csv_escaped . $csv_enclosed,
stripslashes(mysql_field_name($result, $i))) . $csv_enclosed;
$schema_insert .= $l;
$schema_insert .= $csv_separator;
} // end for
$out = trim(substr($schema_insert, 0, -1));
$out .= $csv_terminated;
// Format the data
while ($row = mysql_fetch_array($result))
{
$schema_insert = '';
for ($j = 0; $j < $fields_cnt; $j++)
{
if ($row[$j] == '0' || $row[$j] != '')
{
if ($csv_enclosed == '')
{
$schema_insert .= $row[$j];
} else
{
$schema_insert .= $csv_enclosed .
str_replace($csv_enclosed, $csv_escaped . $csv_enclosed, $row[$j]) . $csv_enclosed;
}
} else
{
$schema_insert .= '';
}
if ($j < $fields_cnt - 1)
{
$schema_insert .= $csv_separator;
}
} // end for
$out .= $schema_insert;
$out .= $csv_terminated;
} // end while
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Length: " . strlen($out));
// Output to browser with appropriate mime type, you choose ;)
header("Content-type: text/x-csv");
//header("Content-type: text/csv");
//header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=$filename");
echo $out;
exit;
}
?>
pero al ejecutarlo me salen los siguientes errores
