Filter url based on parameters
<p>i want to filter the url based on some parameters in it, separated by a plus (+).</p>

<p>This is a sample url:</p>

<p><strong>http://localhost/a.php?f1=a+b+1&amp;f2=c+d+2&amp;f3=e+f+3&amp;.............</strong></p>

<p>Now i want to get each of the parameters in f1, f2, f3....... like i want to fetch the values of a, b, and 1 from parameter f1.</p>

<p>How can i go ahead with this...</p>
