The PHP strval() function converts a given variable to a string. It takes a scalar variable (like integers, floats, and booleans) and converts it to its string representation. For arrays, objects, and resources, it does not work and may produce unexpected results.

Syntax

strval( $variable )

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

The below programs illustrate the strval() function.

Example: In this example we use of the strval() function, which converts the float value 32.360 to a string and prints it. The function ensures the variable is treated as a string.

PHP

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

Output

32.36

Example : In this example we defines a class geeksforgeeks with a __toString() method that returns the class name. Using strval() on an instance of the class prints its name as a string.

PHP

<?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

Example : In this example we demonstrates the strval() function with an array as the parameter. Since strval() does not convert arrays to strings, it prints “Array,” indicating the type, rather than converting the array’s contents.

php

<?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);  ?>

Output

Array
