Subject: [PHP] Auto Incrementing a Variable name?
Hi,
I've been playing with this for a while now. Say I had the following
variables:
$name1 = "joe";
$name2 = "janis";
$name3 = "joanne";
Is there a way in php to increment the variable name not the value?
Something like this....
for ($i = 1; $i <= 3; $i++) {
$arr_name[$i] = $name.$i; // I want $name1,$name2,$name3 etc....
}
This way say if I had 500 database queries that need to be updated I could
just loop through each and just change the record id.....
for ($i = 1; $i <= 500; $i++) {
$query_update = "UPDATE table SET name=' $arr_name[$i]', WHERE
person_id='$i";
$result_update = mysql_query($query_update) or die("Query failed");
}
instead of doing something like this:
$query_update1 = "UPDATE table SET name=' $name1', WHERE person_id='1";
$result_update1 = mysql_query($query_update1) or die("Query failed");
$query_update2 = "UPDATE table SET name=' $name2', WHERE person_id='2";
$result_update2 = mysql_query($query_update2) or die("Query failed");
$query_update3 = "UPDATE table SET name=' $name3', WHERE person_id='3";
$result_update3 = mysql_query($query_update3) or die("Query failed");
etc.....
Anybody? There has to be a way of doing this...
Thanks,
Jeff
