What will be the restrictions/limits for
- key strings (e.g. length, allowed chars, variable interpolation etc.)
- index expressions (e. g. will boolean expressions resolving to 0|1 be also valid, or just simple two operands math with *, +, -)
?
The root variable is still puzzling to me.
v23.50.0015 - 2022-08-15 16:56:
$a
is a "normal" variable
Code: Select all
- Array variables and normal variables with the same base name can be used side by
side like different variables:
$a ="cat"; $a[0] = "dog"; echo $a; echo $a[0]; //"cat", "dog"
v23.50.0016 - 2022-08-16 13:09: and here it's the "root" one, though the code is equivalent.
Code: Select all
$a = "I am Groot!"; //root variable
$a[0] = "Hi!";
