Lookup "Variable Variables" in the PHP manual. You'll use something like:
${$i}

Subject: [PHP-DB] Variables in a loop

I'm trying to write a loop to read variables I receive from a form:
 
<form ...>
<input name=a1 value=..>
<input name=a2 value=..>
<input name=a3 value=..>
<input name=a4 value=..>
 
 
I'd like to get something like:
 
for ($i=1; $i<=10; $i++) { $tab[$i]="a".$i ;}
 
 
The expression "a".$i is actually a string, not a variable. Any idea how to
"read" the value of that string?
 
Thanks for your help.
 
Jean-Louis
