FLOATVAL(3) 1 FLOATVAL(3)
floatval - Get float value of a variable
SYNOPSIS
float floatval (mixed $var)
DESCRIPTION
Gets the float value of $var.
PARAMETERS
o $var
- May be any scalar type. floatval(3) 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(3) Example
<?php
$var = '122.34343The';
$float_value_of_var = floatval($var);
echo $float_value_of_var; // 122.34343
?>
Example #2
floatval(3) non-numeric leftmost characters Example
<?php
$var = 'The122.34343';
$float_value_of_var = floatval($var);
echo $float_value_of_var; // 0
?>
