Re: [PHP] dynamically naming PHP vars on the fly?
You can use variable variables
?php
$nombre = 'Martin';
$name = 'nombre';
echo $$name; # === Martin
You can make more complicated statements with this technique.
$var1 = 'apple';
${ 'Fruit_' . $var1 } = 'organic';
echo $Fruit_apple; // here you are
When your statements are complex use the ${ statement } syntax.
I often use this for hidden global variables.
${ 'try to use this variable directly' } = 'something';
print_r( get_defined_vars() ); # [try to use this variable directly]
= something

HI all
One thing I have been working around but now would love to just do it
finally (and save workaround/longer code hassle) is when:
I need to be able to create a variable (name it, and assign it a value)
whose name is built up from a fixed string concatenated with another string
which comes from the value of another (already set) variable.
Ie:
I want to do this:
(I am just assuming it won't work; I haven't even tried it yet)
$var1='apple';
$Fruit_$var1=organic;
echo $Fruit_apple; // I want this to return organic
Or how are you guys dynamically naming PHP vars on the fly?
