I'm working on a boolean expression configured by the application user. This expression comes from the database as soon as it's a string, I need to make PHP understand it so I have both true and false.
Example:
Expressao_string = ”(1 and ( 0 or 1) )”;
As this string value comes from a base, I need to make this string valid for PHP.
If I understand your question well, the bank is giving you 0 and 1 for Booleans and you want to convert this from string to boolean in php, right?
You do not have to treat anything, php already auto-converts this, see this test I did:
<?php
testar('0');
testar('1');
testar(0);
testar(1);
function testar($testeBool){
if ($testeBool == true){
echo "teste bem sucedido";
}
else{
echo "temos um problema";
}
}
?>
The outputs were:
testar('0'); //temos um problema
testar('1'); //teste bem sucedido
testar(0); //temos um problema
testar(1); //teste bem sucedido
