Re: How MySQL Query and Fetch work?

Hi, Suppose you have a table students: student_id / student_name / GPA here is the code: $sql = "select * from students"; $result = mysql_query($sql); while(list($student_id, $student_name,$gpa)=mysql_fetch_array($result) { echo $student_name." has a GPA of".$gpa."<BR>"; } btw, this is something really basic, you should be able to go to the php.net and read the documentation. there are great examples. --- Alex Shi <chpshi@eol.ca> wrote: > Yesterday I posted a question yet got response.
