Are there any limitations or considerations to keep in mind when using integer, float, string, bool, double, real, and long variable types in PHP?

When using different variable types in PHP, it is important to consider the limitations and potential issues that may arise. For example, integer variables can only store whole numbers, while float and double variables can store decimal numbers but may encounter precision issues. Strings can store text data, but be mindful of memory usage when working with large strings. Boolean variables can only hold true or false values. Real and long variable types are not native to PHP. 

// Example of ensuring correct variable type usage in PHP

// Integer variable
$integerVar = 10;

// Float variable
$floatVar = 10.5;

// String variable
$stringVar = "Hello, World!";

// Boolean variable
$boolVar = true;
