In wordpress wp_options table, option_values are(some values) saved as serialized.So directly we can’t get those values.
Now i’ll tell you easy method to get meta data from wp_options table.

I want to get option name – ” tax_meta_25 “, values.
Values like this.(i want to get values corresponding to ba_pm3 )

a:13:{s:16:"ba_text_field_id";s:4:"0.75";s:6:"ba_fc1";s:4:"1.95";s:6:"ba_fc2";s:4:"1.75";s:6:"ba_fc3";s:4:"1.00";s:6:"ba_pm1";s:4:"2.50";s:6:"ba_pm2";s:4:"2.25";s:6:"ba_pm3";s:4:"2.00";s:6:"ba_se1";s:4:"1.50";s:6:"ba_se2";s:4:"1.00";s:6:"ba_se3";s:4:"0.50";s:5:"ba_i1";s:4:"3.00";s:5:"ba_i2";s:4:"2.50";s:5:"ba_i3";s:4:"2.00";}

First get data like this .

<?php
$val=tax_meta_25; //desired values to be fetched
$opt = $wpdb->get_row("SELECT * FROM $wpdb->options WHERE option_name = '$val'");
$opts=$opt->option_value;
?>
[php]
Now unserialize those data like this.

[php]
<?php
$array = unserialize($opts);
echo $array["ba_pm3 "];
?>

And you have the values

Hope this will help you to get meta data from wp_options table.
