End of file

Excuse me, after I query the data table. Send a query statement to determine whether it is the end of the file. If it is not the end of the file, run the "conditional" while ($result != EOF). This sentence seems wrong? How should I write it?
$sql="select * from table1";
$result=mysql_query($sql);
while($result != EOF)
{
Conditions
}


Help little brother. . Studying! !

Let me answer

while($row = mysql_fetch_array($result,MYSQL_ASSOC)){
print_r($row);
}

I want to determine the end of the file. If it is not the end of file then run the condition. Is it OK to change it to this?
$sql="select * from table1";
$result=mysql_query($sql);
$row=mysql_fetch_array($result,MYSQL_ASSOC);
while ($row!=false)
{
Conditions
}

I am also confused. I want to query the data table and then determine whether it is the end of the file. If it is not the end of the file, run the condition. If it is the end of the file, break out of the loop. How to do this? [img]http://www.111cn.cn/bbs/images/smilies/default/sweat.gif[/img]
$result=mysql_query($sql);
$row=mysql_fetch_array($result,MYSQL_ASSOC);
while ($row!=false)
{
$nowdt=$CustRs["ac_exp_dt"];
$nowmon=$CustRs["ac_exp_mon"];
$nowyr=$CustRs["ac_exp_year"];
$daydiff=(strtotime(date("$nowyr"."-"."$nowmon"."-"."$nowdt")) - strtotime(date("Y-m-d")))/86400;
if ($daydiff else
{mysql_query("UPDATE CUSTOMERS SET Current_Status=1 where indexuid="$CustRS["indexuid"]"");}
}

e....I don't understand your concept: end of file
Does your database query have anything to do with files?

echo mysql_data_seek (mysql_num_rows($sql) -1, $db_resource_link);


Copy code

It is a one-word shortcut to update all records. Update one by one until the end of the record.
