strval

Name

strval — Converts a value to a string.

Synopsis

string strval(var); mixed var: Value to convert to a string

Returns

String value of the given value

Description

strval() converts any scalar value (string, integer, or double) to a string. Resource pointers passed to this function are converted to a string such as "Resource ID #1". If conversion of an array or object is attempted, the function only returns the type name of the value being converted (array and object, respectively).

Note

Due to PHP's dynamic typing, use of strval() is almost never required. In most contexts where a scalar value should be a string, the value will simply act like a string. For example:

$double = 2.2;
$string = "I am a string ";
// The value of $double is used as a string - no explicit conversion is required
print $string . $double; // Displays: I am a string 2.2

Example

Example 1408. Convert a value to a string

$value = 1.223;
print strval ($value);
