Currently, I have this code:
<?php
if (isset($_GET['s'])) {
$itemid = $_GET['s'];
$search = "$itemid";
$query = ucwords($search);
echo "<title>Results for $query</title>";
$string = file_get_contents('http://clubpenguincheatsnow.com/tools/newitemdatabase/items.php');
if ($itemid == "") {
echo "Please fill out the form.";
} else {
echo '<div id="content">';
$string = explode('<br>', $string);
foreach ($string as $row) {
preg_match('/^(.+)\s=\s(\d+)\s=\s(\D+)\s=\s(\d+)/', trim($row), $matches);
if (preg_match("/$query/i", "$matches[1]")) {
echo "<a href='http://clubpenguincheatsnow.com/tools/newitemdatabase/info.php?id=$matches[2]'>";
echo $matches[1];
echo "</a><br>";
}
}
echo '</div>';
}
} else {
echo "Item does not exist!";
}
?>
If "$matches[1]" has nothing in it, I want my code it to echo "Item does not exist!" How do I do this though? Please help!
I've tried something like if ($matches[1]=="") { echo "Item does not exist!"; }
before, but it didn't work. This is what I got:

See works fine right? Look what happens if $matches[1] DOES exist:

It still comes up! How can I make my code so it only echos the error if there is nothing for $matches[1]? PLEASE HELP ME!
If you are wondering, this is my code when I added the if ($matches[1]=="") { echo "Item does not exist!"; }
in:
<?php
if (isset($_GET['s'])) {
$itemid = $_GET['s'];
$search = "$itemid";
$query = ucwords($search);
echo "<title>Results for $query</title>";
$string = file_get_contents('http://clubpenguincheatsnow.com/tools/newitemdatabase/items.php');
if ($itemid == "") {
echo "Please fill out the form.";
} else {
echo '<div id="content">';
$string = explode('<br>', $string);
foreach ($string as $row) {
preg_match('/^(.+)\s=\s(\d+)\s=\s(\D+)\s=\s(\d+)/', trim($row), $matches);
if (preg_match("/$query/i", "$matches[1]")) {
echo "<a href='http://clubpenguincheatsnow.com/tools/newitemdatabase/info.php?id=$matches[2]'>";
echo $matches[1];
echo "</a><br>";
}
}
echo '</div>';
if ($matches[1] == "") {
echo "Item does not exist!";
}
}
} else {
echo "Item does not exist!";
}
?>
Any help to my question would be VERY HIGHLY APPRECIATED!
