PHP | strval() Function

The strval() function is an inbuilt function in PHP and is used to convert any scalar value (string, integer, or double) to a string. We cannot use strval() on arrays or on object, if applied then this function only returns the type name of the value being converted.

Syntax:

strval( $variable ) 

Parameter: This function accepts a single parameter $variable. This parameter represents the value which we want to convert to string

Return value: This function returns a string. This string is generated by typecasting the value of the variable passed to it as a parameter.

Below programs illustrate the strval() function.

Program 1:

<?php

$var_name = 32.360;

// prints the value of above variable
// as a string
echo strval($var_name);

?>

Output:

32.36

Program 2:

<?php

class geeksforgeeks
{
    public function __toString()
    {
        // returns the class name
        return __CLASS__;
    }
}

// prints the name of above class as
// a string
echo strval(new geeksforgeeks);

?>

Output:

geeksforgeeks

Program 3:

<?php
// Program to illustrate the strval() function
// when an array is passed as parameter

// Input array
$arr = array(1,2,3,4,5);

// This will print only the type of value
// being converted i.e. 'Array'
echo strval($arr);

?>
