Write byte array to file in PHP

[hoanghwd]

Hi,
I have array of bytes which is a pdf file
Array ( [0] => 00100101 [1] => 01010000 [2] => 01000100 [3] => 01000110 [4] => 00101101 ....)
I'm wondering how do I write my array into file in PHP
Thanks

How about a for loop or a foreach loop?

$pdfData = "";
foreach ($bytes as $byte) {
    $pdfData .= $byte;
}

And then you can use file_put_conten ts to write it to a file.

P.S.
If you're thinking you should write out each byte individually to the file, don't! A IO write operation is expensive, and it will take many many times longer to be writing the file out in a million byte-sized writes. Compile the output, and then write it.
