hi all,
i have this php statement:
<? if($rowB[$rowA[0]]=='Y') {echo "checked";} ?>
debugging, i got $rowA[0] = 54, but i want $rowB[$rowA[0]] =
$rowB['54'].
is this possible? how do i force $rowA[0] to be a string
('54')?<http://www.php.net/unsub.php>
php should handle the conversion internally for you.
if you want to type cast a value to a string, simply do
(string)$varname

I was thinking about saying that, but php is loosely typed, so 54 ==
'54'. I'm thinking something else is wrong here.

I believe this is the difference with arrays:
$a = array(2 => "foo");
Array(0 => null, 1 => null, 2 => "foo")
$a = array("2" => "foo");
Array("2" => "foo")
not true:
alice:~ jochem$ php -r '
$a = array(2 => "foo"); $b = array("2" => "foo"); var_dump($a, $b);'
array(1) {
[2]=>
string(3) "foo"
}
array(1) {
[2]=>
string(3) "foo"
}
php treats anything that is the string equivelant of an integer as an integer when
it comes to array keys - which comes down to the fact that you cannot therefore use
a string version of an integer as an associative key.
so $a[2] and $a["2"] are always the same element.
the same is not exactly true for floats - although you can use them as array keys you'll
notice in the output of code below that they are stripped of their decimal part (essentially
a floor() seems to be performed on the float value. I have no idea whether this is intentional,
and whether you can therefore rely on this behaviour:
alice:~ jochem$ php -r '
$a = array(2.5 => "foo"); $b = array("2.5" => "foo"); var_dump($a, $b);'
array(1) {
[2]=>
string(3) "foo"
}
array(1) {
["2.5"]=>
string(3) "foo"
}
alice:~ jochem$ php -r '
$a = array(2.6 => "foo"); $b = array("2.6" => "foo"); var_dump($a, $b);'
array(1) {
[2]=>
string(3) "foo"
}
array(1) {
["2.6"]=>
string(3) "foo"
}
