PHP Code:
<?php
$semArray="<B>STUDENTS NAME (6aa05cs001) </B><br><br><br><br><hr><table><tr><td><b>Semester:</b></td><td><b>2</b></td><td></td><td> <b> Result: FIRST CLASS </b></td></tr></table><hr><table><tr><td width=250>Subject</td><td width=60 align=center>External </td><td width=60 align=center>Internal</td><td align=center width=60>Total</td><td align=center width=60>Result</td></tr><br><tr><td width=250><i>Engineering Maths - II (06MAT21)</i></td><td width=60 align=center>51</td><td width=60 align=center>16</td><td width=60 align=center>67</td><td width=60 align=center><b>P</b></td></tr><tr><td width=250><i>Engineering Chemistry (06CHE22)</i></td><td width=60 align=center>40</td><td width=60 align=center>17</td><td width=60 align=center>57</td><td width=60 align=center><b>P</b></td></tr><tr><td width=250><i>Computer Concepts and C Programming (06CCP23)</i></td><td width=60 align=center>70</td><td width=60 align=center>23</td><td width=60 align=center>93</td><td width=60 align=center><b>P</b></td></tr><tr><td width=250><i>Computer Aided Engineering Drawing (06CED24)</i></td><td width=60 align=center>50</td><td width=60 align=center>16</td><td width=60 align=center>66</td><td width=60 align=center><b>P</b></td></tr><tr><td width=250><i>Basic Electronics (06ELN25)</i></td><td width=60 align=center>42</td><td width=60 align=center>17</td><td width=60 align=center>59</td><td width=60 align=center><b>P</b></td></tr><tr><td width=250><i>Computer Programming Lab (06CPL26)</i></td><td width=60 align=center>46</td><td width=60 align=center>24</td><td width=60 align=center>70</td><td width=60 align=center><b>P</b></td></tr><tr><td width=250><i>Engg.

function get_result_for_this_sem($semArray)
{
preg_match("/Semester:<\/b><\/td><td><b>(.)<\/b>/",$semArray,$temp1);
$sem_no=$temp1[1];
preg_match("/Result: (.+)<\/b><\/td><\/tr><\/table><hr><table>/U",$semArray,$temp2);
$sem_final_result=$temp2[1];
preg_match_all("/<i>((.+?)\((.+?)\))<\/i><\/td><td width=60 align=center>([0-9]{1,3})<\/td><td width=60 align=center>([0-9]{1,2})<\/td><td width=60 align=center>([0-9]{1,3})<\/td><td width=60 align=center><b>(.)<\/b><\/td><\/tr>/",$semArray,$temp3,PREG_SET_ORDER);
print_r($temp3);
}
get_result_for_this_sem($semArray);
?>
Here is the output that i get:
Code:
Array ( [0] => Array ( [0] => Engineering Maths - II (06MAT21)511667P [1] => Engineering Maths - II (06MAT21) [2] => Engineering Maths - II [3] => 06MAT21 [4] => 51 [5] => 16 [6] => 67 [7] => P ) )
