How to convert PHP variable to string

Concatenating a variable with an empty string is a common method for converting it to a string in PHP. However, there are more efficient and elegant ways to achieve this.

The PHP solution that most closely resembles the .ToString() method in Java or .NET is the use of casting operators. This allows you to explicitly convert a variable to a specific type.

Example

<code class="php">$myVar = 123;
$myText = (string)$myVar;</code>

After this conversion, $myText will contain the string "123".

Additional Notes

The PHP manual provides comprehensive documentation on string casting and conversion in the Strings section. Notably, it discusses special handling for boolean and null values:

• Boolean values are converted to "1" for TRUE and the empty string "" for FALSE.
• Null values are converted to the empty string.
