Advertencia Por favor tenga en cuenta que las variables variables no pueden usarse con los Arrays superglobales de PHP al interior de funciones o métodos de clase.

One interesting thing I found out: You can concatenate variables and use spaces. Concatenating constants and function calls are also possible. Another use for this feature in PHP is dynamic parsing. Due to the rather odd structure of an input string I varizble currently parsing, I must have a reference for each particular object instantiation in the order which they were created. In addition, because of the syntax of the input string, elements of the previous object creation are required for the current one.

Normally, you won't need something this convolute. In this example, I needed to load an array with dynamically named objects - yes, this has some basic Arw Oriented programming, please bare with me. I haven't fully tested the implimentation of the objects. The scope of a variable-variable's object attributes get all that? Regardless, this is another example of the manner in which the var-vars can be used with precision where tedious, extra hard-coding is the only alternative.

Then, we can easily pull everything back out again using a basic array function: foreach. While not relevant in everyday PHP programming, it icentifier to be possible to insert whitespace and comments between the dollar signs of a variable variable. All three comment styles work. This information becomes relevant when writing a parser, tokenizer or something else that operates on PHP syntax.

The feature of variable variable names is welcome, but it should be avoided when possible. It's a kind of magic : This may really make it hard to refactor code. PHP actually supports invoking a new instance of a class using a variable class name since at least version 5. These are the scenarios that you may run into trying to reference superglobals dynamically. Whether or not it vafiable appears to be dependent are variable and identifier the same the current scope.

There was no problem because they were only referenced via a variable variable. I only saw a parse error much later, when I tried to reference one directly. It took a while to realise that illegal hyphens were the cause because the parse error only occurs on assignment. The 'dollar dereferencing' to coin a phrase doesn't seem to be limited to two layers, even without curly abd. Then you must provide the full namespaced identifier of the class as shown below.

Instancing a class normally not through a variable does not require the namespace. Variable variables techniques do not work when one of the "variables" is a constant. The example below illustrates this. This is probably the desired are variable and identifier the same for constants, but was confusing for me when I was trying to figure it out. Echoing the same variable variable using the function that created it results in the same return and therefore the same variable name is used in the echo statement.

Have fun. Note vvariable normal variable variables will not be parsed in double-quoted strings. You'll have to use the braces to make it work, to resolve the ambiguity. Neither simple class name nor containing subnamespace works. The example given in the php ate is confusing! This is a handy function I put together to allow variable variables to be used with arrays.

To use the function, when you want to reference an array, send it in the meaning of force in urdu 'array:key' rather than 'array[key]'. Sometimes you might wish to modify value of an existing variable by its name. This is easily accomplishable with a combination of using "passing by reference" and "variable variables".

By the way Even outside a function or a class method variable variables cannot be used with PHP's Superglobal arrays. There is no need for the braces for variable object names Hope this helps
