Re: Auto Incrementing a Variable name?

Should be: ${name$i} Jeff Pauls wrote:

I get an error with this. PHP doesn't like "$name$i". for ($i = 1; $i <= 3; $i++) {

} I've looked at Variable variables but I don't think that is what I need. What about if I wanted something like $name_1_ff $name_2_ff $name_3_ff neither of these work. $name_$i_ff $name_.$i._ff Having something after causing more of a problem. First of all PHP can't find the value of "$name_" and "_ff" just breaks it more.

You're on the right track: for ($i = 1; $i <= 3; $i++) {

$arr_name[$i] = $name$i;         // I want $name1,$name2,$name3 etc....

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
