Is there any nice way to convert a string containing either "TRUE" or
"FALSE" to a bool with the appropriate value? I know I can just "if
(strcmp..." but, as the song goes on to say "...ugly, so ugly, it's ugly"[1]
What is the response when the string is NOT "TRUE" or "FALSE"?
<?php
$s_OriginalValue = 'FALSE';
$b_Test = in_array($s_Test = strtolower($s_OriginalValue),
array('true', 'false')) ? !!strcmp($s_Test, 'false') : null;
var_dump($b_Test);
$s_OriginalValue = 'TRUE';
$b_Test = in_array($s_Test = strtolower($s_OriginalValue),
array('true', 'false')) ? !!strcmp($s_Test, 'false') : null;
var_dump($b_Test);
$s_OriginalValue = 'GARBAGE';
$b_Test = in_array($s_Test = strtolower($s_OriginalValue),
array('true', 'false')) ? !!strcmp($s_Test, 'false') : null;
var_dump($b_Test);
?>
outputs ...
bool(false)
bool(true)
NULL
This is one of those threads where you can go mad with proposals, thus:
$value = constant($value);
just so happens that constant() is case insensitive and there are
constants "true" and "false"
<?php
var_dump( constant("false") );
var_dump( constant("FALSE") );
var_dump( constant("true") );
var_dump( constant("TRUE") );
//output
bool(false)
bool(false)
bool(true)
bool(true)
