Error received from database was #1064 - PHP & MySQL - php

Question

I have a simple MySQL query that I use in PHP but it gives me this error;
Database query failed. Error received from database was #1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'NULL' at line 3 for the query: SELECT *
FROM mantis_user_table
WHERE email LIKE '%me%'.
$t_user_table = db_get_table( 'mantis_user_table' );
$temp_mail = '%' . $p_email . '%';
$query = "SELECT * FROM $t_user_table WHERE email LIKE '{$temp_mail}'";
$result = db_query_bound( $query, Array( $p_realname ) );
The thing I can not understand is, when I run it in phpmyadmin, it gives me the correct values.
So can you please help me with this situation ?
Thank you
EDIT :
This is the code that I use while editing :
$File = "c:/YourFile.txt";
$Handle = fopen($File, 'w');
$Data = $query;
fwrite($Handle, $Data);
fclose($Handle);
Here you can see the query that I get when I write :
SELECT * FROM mantis_user_table WHERE email LIKE '%meh%'
And this query normally gives me some results in phpmyadmin , now I dont have any result on web site
And if you want this is the rest of the code that returns the id of the selected item:
$result = db_query_bound( $query, Array( $temp_mail ) );
if( 0 == db_num_rows( $result ) ) {
return false;
} else {
$row = db_fetch_array( $result );
user_cache_database_result( $row );
return $row['id'];
}

Answer 1

try making
$query = 'SELECT * FROM $t_user_table WHERE email LIKE "{$temp_mail}"';
(some versions of mysql don't recognize ' symbol)
