floatvalGet float value of a variable

Description

floatval(mixed $value): float

Gets the float value of value.

Parameters

value

May be any scalar type. floatval() should not be used on objects, as doing so will emit an E_NOTICE level error and return 1.

Return Values

The float value of the given variable. Empty arrays return 0, non-empty arrays return 1.

Strings will most likely return 0 although this depends on the leftmost characters of the string. The common rules of float casting apply.

Examples

Example #1 floatval() Example

<?php
$var 
'122.34343The';
$float_value_of_var floatval($var);
echo 
$float_value_of_var// 122.34343
?>

Example #2 floatval() non-numeric leftmost characters Example

<?php
$var 
'The122.34343';
$float_value_of_var floatval($var);
echo 
$float_value_of_var// 0
?>
