error on show all date items from datebase

error on show all date items from datebase:

on datebase:

Title1
Title2
Title3

php code:

$postdb = mysql_query("SELECT * FROM wtable");
$post = mysql_fetch_assoc($postdb);

while ($poste = @mysql_fetch_array($postdb))
  {
  echo $poste['posttitle'];
  echo "开发者_运维知识库<br />";
  }

output:

Title2
Title3

$post = mysql_fetch_assoc($postdb);

Is returning the first result and then moving the cursor forward.

Comment out this line and try again.

Example:

$postdb = mysql_query("SELECT * FROM wtable");
//$post = mysql_fetch_assoc($postdb); <-- comment out this line

while ($poste = mysql_fetch_array($postdb)) { // <-- don't use @ here, we want to know if something went wrong!
  echo $poste['posttitle'];
  echo "<br />";
}
