[PHP] Newbie: Site search, more than one directory

[Steve Wright]

Hey,

I have just developed a simple site search.. .and am after learning how to
get it to search all directories... at present, it only searches the one it
is in!!


Here's the code:

<?
include("include/common.inc");
$title = "Search";
include("include/header.inc");
?>
    <P>
        <FORM ACTION="<? echo "$PHP_SELF"; ?>" METHOD="POST">
        <INPUT TYPE="text" NAME="searchstr" value="<? echo "$searchstr"; ?>"
               SIZE="20" MAXLENGTH="30">
        <INPUT TYPE="submit" VALUE="Search!">
        </FORM>
    </P>
        <?
        if ( ! empty($searchstr) ) {
            // empty() is used to check if we've any search string
            // if we do, call grep and display the results.
            echo "<HR>\n";
            // call grep with case-insensitive search mode on all files
            $cmdstr = "grep -i $searchstr *";
            $fp = popen( $cmdstr, "r" ); file://open the output of command
as a  pipe
            $myresult = array(); // to hold my search results
            while( $buffer = fgetss ($fp, 4096 )) {
                // grep returns in the format
                // filename: line
                // So, we use split() to split the data
                list($fname, $fline) = split(":",$buffer, 2);
                // we take only the first hit per file
                if ( !defined($myresult[$fname]))
                    $myresult[$fname] = $fline;
                }
                // we have results in a hash. lets walk through it and print
it
                if ( count($myresult) ){
                    echo "<OL>\n";
                    while(list($fname,$fline) = each($myresult))
                    echo "<LI>
                   <A HREF=\"$fname\">$fname</A> : $fline </LI>\n";
                    echo "</OL>\n";
                } else {
                    // no hits
                    echo "Sorry. Search on <B>$searchstr</B>
                          returned no results.<BR>\n";
                }
                pclose($fp);
            }
        ?>
<?
include("include/footer.inc");
?>



I think it centers around the line whcich contains but am not definate:
while( $buffer = fgetss ($fp, 4096 )) {


Any help much appreciated..
