1.2.983. Possible TypeError¶
Report possible errors when a string is given to a int or float typed container.
That error will be emitted when strict_types is active, or if the string cannot be formatted into a float or an int. Otherwise, the code works as intended.
It is recommended to set a try/catch around those expressions, to catch them.
<?php
// This is OK, as the string will be successfully turned into a float
foo("12.34");
// This is KO, as the string will not bet turned into a float
foo("12.34a");
function foo(float $price) {
intdiv($price, 3);
}
?>

1.2.983.1. Suggestions¶
Add the try expression around the assignation, to catch the error
Validate the incoming value to ensure it can be converted to the target type
Cast the value to int or float
