PHP Array into mysql select Statement - php

Question

I have an issue where i have a textarea in a form where users can enter names on seperate lines. On submit I explode the "\n".
I then want to pass the values from the array into an Select statement, but when i run the script it only returns one result (the last one) from the array..
here is the code below.
echo "<h1> You searched for the following names </h1>";
include 'conn.php';
mysql_select_db("email_finder", $con);
$Email = $_POST['EmailBox'];
$str = $Email;
$lines = explode("\n", $str);
//$in = implode(',', $lines);
//$userStr = implode(',', $lines);
echo "<table border='0'>
<tr>
<th style='color:White' width='180px'; bgcolor=#999999>Name</th>
<th style='color:White' width='250px'; bgcolor=#999999>Email</th>
</tr>";
echo "<pre>";
print_r($lines);
echo "</pre>";
foreach($lines as $array_element) {
$result = mysql_query("SELECT * FROM `emails` WHERE `Name` IN('$array_element') ORDER BY `LastName`");
echo "<pre>";
print_r($array_element);
echo "</pre>";
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
echo "<tr>";
echo "<td style='padding-left:5px'><b> ".$row['Name']."</b>&nbsp:&nbsp</td>";
printf("<td style='padding-left:5px'>" .$row['Email']. "</td>");
echo "</tr>";
echo "<pre>";
print_r($row);
echo "</pre>";
}
}
echo "</table><br />";
echo "Email <b>ALL</b> these Students: <a href=mailto:".$row['Email']." >Click Here</a> <br />";
mysql_close($con);
echo '<br />';
If you can help i would be greatful

Answer 1

Try using equals instead of IN:
$result = mysql_query("SELECT * FROM emails WHERE Name='$array_element' ORDER BY LastName");
Otherwise my advise to debug it would be to put an exit(); statement on your first pass of the while loop to check your array value and/or if you get a result of the first entry. something like:
foreach($lines as $array_element) {
$result = mysql_query("SELECT * FROM `emails` WHERE `Name`='$array_element' ORDER BY `LastName`");
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
print_r($row);
exit;

Guessing you've got OS specific line endings tripping you up. Try preg_split
$lines = preg_split("/\\n|\\r|\\r\\n/", $str);
