[PHP] Auto Incrementing a Variable name?

2003-02-25 Thread Jeff Pauls 
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

Variable variables allows you to define a variable name from a string.

Re: [PHP] Auto Incrementing a Variable name?

2003-02-25 Thread Jeff Pauls 
I get an error with this. PHP doesn't like $name$i.

for ($i = 1; $i = 3; $i++)  {
 $arr_name[$i] = $name$i; // I want $name1,$name2,$name3 etc
}

 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.

Re: [PHP] Auto Incrementing a Variable name?

2003-02-25 Thread Jeff Pauls 
I think I have something that will do the trick thanks to everyones help.

$name_1_aaa = Jimmy;
$name_2_aaa = Janis;
$name_3_aaa = Joe;

for ($i = 1; $i = 3; $i++)  {
$arr_name[$i] = 'name_'.$i.'_aaa';
}

echo ${$arr_name[1]}.'br';
echo ${$arr_name[2]}.'br';
echo ${$arr_name[3]}.'br';

Displays:

Jimmy
Janis
Joe

Now I can do something like this for all my updates

for ($i = 1; $i = 3; $i++)  {
$query_update = UPDATE table SET name='${$arr_name[$i]}' WHERE
name_id='$i';
 $result_update = mysql_query($query_update) or die(Query failed);
}


Thanks for all the help!

Jeff
