PHP | strval() Function - GeeksforGeeks

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); 
  
?>
