syntax question - eregi()

I'm having difficulty understanding what the array does or refers to in the eregi() function using php. Listing below are returned strings with [0] [1] [2] .............................................. <? $fp =fopen("C:\\TextFiles\\Test.htm","r"); $content = fread($fp,100000); eregi("<b>(.*)<hr width",$content,$match); $FinalLine=$match[2]; echo "$FinalLine"; ?> ........................... quick brown fox jumped over the lazy dog // output with $match[1] ................................. quick brown fox jumped over the lazy dog. <hr width // output with $match[0] .................................. file://output is nothing with $match[2] ................................... Description: int eregi ( string pattern, string string [, array regs]) ........................ Thank you. Tony Ritter
