PHP hint Warning:mysql_fetch_array () expects_php Tutorial

My height code is as follows

Include ("conn.php");

if (!empty ($_get[' id ')) {
$sql = "SELECT * from news where ' id ' = '". $_get[' id '). "'";
$query =mysql_query ($sql);
$rs = Mysql_fetch_array ($query);
}

The hint is wrong.

Warning:mysql_fetch_array () expects parameter 1 to BES resource, boolean given in F:xmappwww.bkjia.c0mmylibrarysearch_res Ult.php on line 32

Later I upgraded the code

if (!empty ($_get[' id ')) {
$sql = "SELECT * from news where ' id ' = '". $_get[' id '). "'";
$query =mysql_query ($sql);
if (Mysql_num_rows ($query)
{
$rs = Mysql_fetch_array ($query);
}
Else
{
Mysql_error ();
}
}

This will see the MySQL error message, the result is a SQL statement has a problem, the SQL statement can be modified,

A small series of tutorials tips you, cause this kind of error is our grammar is not standardized, if you want to handle only the SQL to do a strip of output processing or in mysql_query (SQL) or Die (Mysql_error ()) to handle this site original reprint must indicate the source/HTTP/ Www.bKjia.c0m/phper/php.html
