svg apache php configeration

i am trying to implement the following simple code using the server apache and php script
but the result is an xml nodeset not the svg graph
how can i configer the system to be abe to comunicate with each other

thanks

<?php
header&#40;"Content-type&#58; image/svg+xml"&#41;;
echo '<?xml version="1.0" encoding="iso-8859-1" ?>';
?>
<svg viewBox="0 0 500 500" >
<rect x="0" y="0" width="50" height="50" >
<text x="12" y="20" style="font-size&#58;10px;"> My Text</text>
</rect>
</svg>

Try this

<?php
header("Content-type: image/svg+xml");
print('<?xml version="1.0" encoding="iso-8859-1" ?>');
print('<svg viewBox="0 0 500 500" >');
print('<rect x="0" y="0" width="50" height="50" >');
print('<text x="12" y="20" style="font-size:10px;"> My Text</text>' );
