How to convert an Integer Into a String in PHP ?
The PHP strval() function is used to convert an Integer Into a String in PHP. There are many other methods to convert an integer into a string.
In this article, we will learn many methods.
Methods:
- Using strval() function.
- Using inline variable parsing.
- Using explicit Casting.
Method 1: Using strval() function.
Note: 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 )
Return value: This function returns a string. This string is generated by typecasting the value of the variable passed to it as a parameter.
Example:
PHP
<?php $var_name = 2; // converts integer into string $str = strval ( $var_name ); // prints the value of above variable as a string echo "Welcome $str GeeksforGeeks" ; ?> |
Welcome 2 GeeksforGeeks
Method 2: Using Inline variable parsing.
Note: When you use Integer inside a string, then the Integer is first converted into a string and then prints as a string.
Syntax:
$integer = 2; echo "$integer";
Example:
PHP
<?php $var_name = 2; // prints the value of above variable // as a string echo "Welcome $var_name GeeksforGeeks" ; ?> |
Welcome 2 GeeksforGeeks
Method 3: Using Explicit Casting.
Note: Explicit Casting is the explicit conversion of data type because the user explicitly defines the data type in which he wants to cast. We will convert Integer into String.
Syntax:
$str = (string)$var_name
Example:
PHP
<?php $var_name = 2; //Typecasting Integer into string $str = (string) $var_name ; // prints the value of above variable as a string echo "Welcome $str GeeksforGeeks" ; ?> |
Welcome 2 GeeksforGeeks
