PHP convert from MySql to Excel auto-negotiation table columns

Question

I am currently exporting tenant data from my MySql database to an Excel spreadsheet using the code below.

<?php
    require_once('../../../includes/config.inc.php'); 

    require_once(MYSQL);

    $query = "SELECT * FROM tenant";        //Define the SQL query

    if ($result = $dbc->query($query))
    {
        $file_type = "vnd.ms-excel";
        $file_ending = "xls";

        header("Content-Type: application/$file_type");
        header("Content-Disposition: attachment; filename=tenant_data.$file_ending");
        header("Pragma: no-cache");
        header("Expires: 0");

        $seperator = "\t";  //define separator (defines columns in excel)

        $field_count = $result->field_count;

        for ($for_count = 1; $for_count < $field_count; $for_count++)   //start of printing column names as names of MySQL fields
        {
            $result->field_seek($for_count);

            $field_info = $result->fetch_field();

            $field_name = $field_info->name;

            $field_name_title = str_replace("_", " ", "$field_name");

            $field_array[] = $field_name;

            echo $field_name_title . $seperator; 
        }

        $result->field_seek(0);

        print("\n");        //end of printing column names

        while($row = $result->fetch_assoc())    //start while loop to get data
        {
            $schema_insert = "";

            for ($col_count = 0; $col_count < $field_count - 1; $col_count++)
            {
                $current_field = $field_array[$col_count];

                if ($row[$current_field] != "")
                {
                    $schema_insert .= "$row[$current_field]" . $seperator;
                }
                else
                {
                    $schema_insert .= "" . $seperator;
                } 
            }

            $schema_insert = str_replace($seperator . "$", "", $schema_insert);

            $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert);            //Replaces \n or \r with a space

            $schema_insert .= "\t";

            print(trim($schema_insert));

            print "\n";
        }
    }
?>

The code is currently working, however I have two problems:

1) I want the columns in the spreadsheet to automate the size of the content upon creation.

2) In the data there is a field “Phone”, where numbers tend to start with 0. As a result, 0 is omitted in the database, and I think that the column should be indicated as a string.

Does anyone know how to do this? I don't want to use PHPExcel, as this seems like massive over-complication when that's all I want to do.
