How can i invoke a jquery script multiple times by using a php foreach loop.The jquery script draws a pie chart based on data present in the session for every iteration of the loop.

PHP is server side, JavaScript (jQuery) is client side. You cannot use PHP to invoke a JavaScript function.
You can write a new script tag or jQuery function in the foreach loop
echo '<script>';
foreach(....){
echo 'drawPieFunction();';
}
echo '</script>';
highly recommend against this though since it has next to no good uses

This would call jsFunction() 10 times with params from 0 to 10
<script type="text/javascript">
$(document).ready(function(){
<?php
for($i=0; $i <= 10; $i++;){
echo 'jsFunction(' + $i + ')';
}
?>
});
</script>
Which is equivalent to simply writing (and will output this to page):
<script type="text/javascript">
$(document).ready(function(){
jsFunction(0);
jsFunction(1);
jsFunction(2);
jsFunction(3);
jsFunction(4);
jsFunction(5);
jsFunction(6);
jsFunction(7);
jsFunction(8);
jsFunction(9);
});
</script>
You can also adapt your javascript function to accept arrays as parameter.
If so you can via PHP set values of an array and then call the function only one time:
<script type="text/javascript">
<?php
echo "var arrayPies = [";
for($i=0; $i <= 10; $i++){
echo ($i<10) ? "$i," : "$i";
}
echo "];\n";
echo "callPieFunction(arrayPies);";
?>
</script>
The above code will output something like this:
var arrayPies = [0,1,2,3,4,5,6,7,8,9,10];
callPieFunction(arrayPies);
