Graph not showing properly
<p>Hi All I have created a graph using php, though the script is workin correct when it is run seperately but when i put with other code instead of graph some strange characters show, the error is :   Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\samplesite\header.php:99) in C:\xampp\htdocs\samplesite\Pets\Dogs\Afgan Hound.php on line 161</p>

<p>header.php has been included at the start of page.</p>
