If I download a file from a website using:
$html = file_get_html($url);
Then how can I know the size, in kilobyes, of the HTML string? I want to know, because I want to skip files over 100Kb.
If you do
file_get_contents, you’ve already gotten the whole file.If you mean “skip processing”, rather than “skip retrieval”, you can just get the length of the string:
strlen($html). For kilobytes, divide that by 1024.This is imprecise because the string may contain UTF-8 characters over one byte in length, and very small files will actually occupy a FS block instead of their byte length, but it’s probably good enough for the arbitrary-threshold cutoff you’re looking for.
