note 74373 added to function.fpassthru

(Do not delete this, it is NOT a bug report. It is a *follow up* to vague comments on the page about fpassthru() using excessive memory, and a usage tip that if you want to use pass-through processing, PHP 5 is strongly advised. It may LOOK like a bug report because unlike earlier tips, I've tried to clarify the situation. It is not a bug report because the problem is RESOLVED in PHP 5. Rather, anyone still using PHP 4 (for example, for compatibility reasons) should simply be aware that the problem is now resolved.) In PHP 4 (4.4.4 tested as a CGI, Apache 2, Linux), use of both fpassthru() and fread() in a loop suffer the SAME memory "leakage". This is characterised by all data that is sent to the client also being kept inside PHP and not released. It would appear to be a failure to garbage collect the data. In PHP 5 (5.2.1 tested as a CGI, Apache 2, Linux) this flaw is resolved in both cases. Neither fpassthru() nor fread() in a loop "leak" memory during execution. The issue of which one to use appears not to be an issue of memory as both were equally flawed in PHP 4 and both are equally fixed in PHP 5. Speed, is left to a reader exercise to test in the latest PHPs. ---- Server IP: 194.145.210.4 Probable Submitter: 82.28.36.206 ---- Manual Page -- http://www.php.net/manual/en/function.fpassthru.php Edit -- https://master.php.net/note/edit/74373 Del: integrated -- https://master.php.net/note/delete/74373/integrated Del: useless -- https://master.php.net/note/delete/74373/useless Del: bad code -- https://master.php.net/note/delete/74373/bad+code Del: spam -- https://master.php.net/note/delete/74373/spam Del: non-english -- https://master.php.net/note/delete/74373/non-english Del: in docs -- https://master.php.net/note/delete/74373/in+docs Del: other reasons-- https://master.php.net/note/delete/74373 Reject -- https://master.php.net/note/reject/74373 Search -- https://master.php.net/manage/user-notes.php
