Time\Duration::fromIso8601DurationString() ignores everything after a NUL byte. #24504
Description
Description
The following code:
<?php
foreach (["PT1Sgarbage", "PT1S\0garbage", "PT1H\0x", "PT1S\0"] as $input) {
try {
$d = Time\Duration::fromIso8601DurationString($input);
printf("%-18s => accepted: %d s\n", json_encode($input), $d->seconds);
} catch (Time\TimeException $e) {
printf("%-18s => rejected: %s\n", json_encode($input), $e->getMessage());
}
}Resulted in this output:
"PT1Sgarbage" => rejected: The ISO 8601 duration string could not be parsed
"PT1S\u0000garbage" => accepted: 1 s
"PT1H\u0000x" => accepted: 3600 s
"PT1S\u0000" => accepted: 1 s
But I expected this output instead:
"PT1Sgarbage" => rejected
"PT1S\u0000garbage" => rejected
"PT1H\u0000x" => rejected
"PT1S\u0000" => rejected
