Did you never programed in javascript or C++?
That is basic in this languages, its no a bad practice.

PHP:

```csharp
if(!$ola)
{
echo "ola is null";
}
else
echo "value of ola is $ola";
```

Output
ola is null

```csharp
$ola = "its native in php";
if(!$ola)
{
echo "ola is null";
}
else
echo "value of ola is $ola";
```
Output
value of ola is its native in php
