Convert Variable From Float To String In PHP

Converting variables in PHP from one type to another is a common task in programming. In this article, we will look at how to convert a variable from float to string in PHP, a process that can be helpful in situations where you need to process or display number values in a string format.

Code snippet for Converting Variable From Float To String

$floatValue = 10.56;
$stringValue = strval($floatValue);

echo gettype($stringValue); // Returns: string
echo $stringValue; // Returns: 10.56

Code Explanation for Converting Variable From Float To String

In the code snippet above, we are first declaring our float value $floatValue and setting it to 10.56.

The strval() function in PHP is used to convert a variable to a string. Therefore, to change our float to a string, we use $stringValue = strval($floatValue); This line of code converts the float value from $floatValue to a string and assigns it to the variable $stringValue.

The gettype() function is then used to get and display the type of the newly converted $stringValue variable, which will return string.

Finally, echoing $stringValue will output the original float value, but now in a string format, hence will return 10.56 as a string.

Therefore, by using the strval() function, we can effectively convert a variable from float to string in PHP. The gettype() function can also assist in confirming the new variable type. Remember, though the float value appears the same after being converted to string, the data types are fundamentally different and behave differently in different contexts in PHP.
