PHP echo variables when I don't know which ones are going to show


Maybe this can help you:

$blocked_holidays=array("a", "b", "c");
$a=1; $b=2; $c=3; //testing values

 $blocked_string=array();
 foreach ($blocked_holidays as $value) {
    array_push($blocked_string, ${$value});
 }
 echo '['.implode($blocked_string, ',').']';

EDIT

I think i get what you are trying to do:

$blocked_string=implode(", $",
$blocked_holidays);
$blocked_string=eval('echo
"[$'.$blocked_string.']";');
echo $blocked_string;

//or simply
$blocked_string=eval('echo "[$'.implode(", $",
$blocked_holidays).']";');

Turn ALL current workspace variables into global variables
The answer is, use structure files instead of globals. once the struct is created, (c.constant1, c.constant2...), you just give the function in question c. I used to work with workspace a lot, which explains why I save my workspace and load it once (not many times since constants dont change) so this is how it looks for me: mainfunction c.constant1=1; save c.mat [Time,Results] = ode15s(@(x, c) f

Should single-use values be inline, function-level const variables, or class-level static const variables?
What do you prefer? They're not all equivalent of course. If you give them (named) namespace or global scope, they can get external visibility, meaning you can define them in a separate TU and even change their definition without recompiling (just linking). If that TU is in a dynamic library that linking might be at runtime. Also, function locals are usually not separately documented. However i

Variables set of three?
The function returns a tuple return jelly_beans, jars, crates or more explicitly return (jelly_beans, jars, crates) The next part is called tuple unpacking sometuple = secret_formula(start_point) beans, jars, crates = sometuple since your function returns a tuple of 3,it can be unpacked to 3 variables you can also do this in one step beans, jars, crates = secret_formula(start_point)

C - stdin to variables
If you want to extract integers from a string,use sscanf(arr,"%d %d",&num1,&num2); Where arr is the array of char containing data from which you want to extract two integers and num1 and num2 are two int variables. Or else you can directly scan two ints using scanf("%d %d",&num1,&num2); It is better to check if scanf (or sscanf) is successful. Both of these will return 2(in
