Here is some more that you may find useful:
In your hypothetical example:
$num = '123_456_789',
$num is a string.
and I presume you mean that this is hard coded into your source file
code and you want to be able to read the source code with greater
ease.
So you can hard code it this way and if you want to use the value
as an
actual number in some mathmatical processing:
settype does not return anything accept true or false.
One could use intval()/floatval() or an (int)/(float) cast instead.
Actually what should work with settype is
$num = '123_456_789';
settype(str_replace('_', '', $num), 'int')
settype should coerce the data type in place to an int. (of float if
you use 'float' as the second argument to settype
I got this to work
<?php
$num = '123_456_789';
$num = str_replace('_', '', $num);
settype($num, 'int');
print "\$num += 1: ".$num += 1;
?>
settype(str_replace('_', '', '123_456_789'), 'int');
or--
$num = '123_456_789';
function use($num)
{
settype(str_replace('_', '', $num), 'int')
}
$num = use($num);
Or settype( string, 'float') if there is a decimal fraction
involved.
