How to use strval() function in PHP?

This article will introduce to you how to use the strval() function in PHP. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

The strval() function is a built-in function in PHP that is used to convert any scalar value (string, integer or double) to a string. We cannot use strval() on arrays or objects, this function only returns the type name of the value to be converted if it is applied.

Syntax:

strval( $variable )

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

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

The following program illustrates the strval() function.

Program 1:

<?php
  
$var_name = 32.360;
  
// prints the value of above variable 
// as a string
echo strval ( $var_name );
  
?>

The output is as follows:

32.36

Program 2:

<?php
  
class lsbin
{
     public function __toString()
     {   
         // returns the class name 
         return __CLASS__ ;
     }
}
  
// prints the name of above class as
// a string
echo strval ( new lsbin);
  
?>

The output is as follows:

lsbin

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. &#39;Array&#39;
echo strval ( $arr );
  
?>
