quick fgets() question

[Gasolene]

does the length parameter have to be the size of the file or just the size of that line??

[LordShryku]

It can be whatever size you set it to...

[Gasolene]

sorry, I didn't make that clear

I meant that does the length parameter need to be at least the size of the entire file??

[LordShryku]

That's the same question. That parameter doesn't even need to be specified. You could set that parameter to 1 if you wanted to.

Did you read the docs on fgets? I'm thinking you want fread, not fgets. fgets is line oriented. I.e.

$line = fgets($fp,4096);

will result in $line having ONE line of the file pointed to by $fp. I.e. it's only gonna grab a single line.

$body = fread($fp,1000000);

will read the first 1000000 bytes of the file pointed to by $fp. A neat trick to read the whole file:

$file = "/usr/share/dict/words";
$fp = fopen($file,"r");
$body = fread($fp,filesize($file));
