File permissions for fopen in write mode - PHP

Question

I have a PHP script that writes some rows to a CSV file:

$fp = fopen($csv, 'w');

I'm using mode 'w' so that it will create the file if it doesn't exist, however the file is automatically given 644 permissions even though I gave 777 to the whole /var/www/html/ directory (not a good idea but suitable for testing).

How can I write to the file and give it permissions beforehand? Or is there a better way to give write permissions?

are you having trouble writing to the file? 644 should be fine for writing as the owner has read/write permissions. — Matt K, Aug 15 '12 at 14:18
@MattK It seems to create the csv under the owner of 'Apache' which is different than the owner of all the other files in the directory — AlxVallejo, Aug 16 '12 at 20:53

To create the file before hand and set permissions:

touch('/file/path/here');
chmod('/file/path/here', 0775);
fopen('/file/path/here', 'w');

But, this should not be an issue. If the PHP/Apache user is creating the file using fopen, they have permissions to write to it.

The owner seems to change to 'apache'. I don't want to hardcode an owner into PHP because the domain might change. – AlxVallejo Aug 16 '12 at 21:11
Did you experience any different behavior with the code above? – Mike Mackintosh Aug 16 '12 at 21:14
