Subject: [PHP] Searching arrayed file... Suggestions?
Greetings.
I have made a try to write a search engine for a site I run. This search
iterates through all links which are made up like so:
"|BY|EMAIL|CATEGORY|FOLDER/BAND|LINKNAME|LINKURL|". Now, I use the code:
if ($txtLinkname=="") return;
$logfile="entries.txt";
$file_line = file($logfile);
$total_lines = count($file_line);
// Start printing the header of the table. The rest is completed, nested
// course.. in the incrementation-loop.
echo"<table width=60% cellpadding=0 border=0 cellspacing=0
align=center>";
echo"<tr><td width=100% valign=top align=left>";
for($i=($total_lines-1); 0 <= $i; $i--) { $line[] = $file_line[$i]; }
echo "<p><b>Searching for links containing $txtLinkname...<br>";
echo "<hr noshade>";
echo "</b>";
for ($i=0; $i < $total_lines; $i++){
$line_array = explode("|",$line[$i]);
$swhere=strtolower($line_array[5]);
$swhat=strtolower($txtLinkname);
$pos = strpos ($swhere, $swhat);
if ($pos<0) {
// not found
}else if (($pos>1) && (!empty($pos))) {
$found++;
echo"<b>Name:</b> $line_array[1]<br>\n";
echo"<b>Email:</b> <a
href=\"mailto:$line_array[2]\">$line_array[2]</a><br>\n";
echo"<b>Category:</b> $line_array[3]<br>\n";
echo"<b>Band/Folder:</b> $line_array[4]<br>\n";
echo"<b>Link Name:</b> $line_array[5]<br>\n";
echo"<b>Link URL:</b> <a href=\"$line_array[6]\"
target=\"_blank\">$line_array[6]</a><br>\n";
echo "<hr noshade>";
}
}
echo "<h3>";
if ($found==0) {
echo "No links found containing '$txtLinkname'!<br>";
}else{
echo "<br>Found: $found links containing $txtLinkname<br>";
}
echo "</h3><h4>";
echo "[ <a href=\"post3.htm\">POST LINK</a> | <a
href=\"index.php?action=view\">VIEW LINKS</a> ]";
$found=0;
echo "</h4>";
?>
And that is all the code I use. Where have I done wrong? You see, the
problem is that I found only some links, but not all. And if I have a link
called "Necrolust - Tribute to MayheM", it cannot find the "Necro" nor
"necRO". And as you can see, I HAVE used uppercase methods to find portions
and so forth. Any help is suggested!!
