fread of my php, fwrite is cut-off

3dron

I am reading one of my PHP files and trying to write it to an HTML file. But the HTML file ends up cut-off at around the 15k mark. I have set fread bytes at 102400.

I encountered this problem years ago and forgot my solution.

Is the fwrite occuring faster than the fread can complete? Or does the fread command happen completely before next command is executed?

Please help.

100 kB
I dont know how long that would take .....
Normally not long enough to script time out
But if you both read & write 100kB in same script, then we have 200 kB
But this wouldnt take many seconds to do for PHP.
Maybe 2-5 seconds, I guess.

Anyway, you can try this,
http://php.net/manual/en/function.set-time-limit.php

set_time_limit( seconds ); will change the phpinfo() setting
max_execution_time which is by default 30 seconds

If you put this in beginning of your script
it will not time out until 60 seconds

<?php

set_time_limit( 60 );

?>

I hardly think this will solve your issue.
It is probably something else that makes your file operation cut-off

My output file is expected to only be around 25k size.

I was just stating that my read was large enough andnot the bottleneck.

If it's the same instance of the script that's both reading and writing the file then there shouldn't be a problem (without seeing the relevant code it's hard to say) since PHP is single-threaded.

If another script or another instance of the same script is trying to read the file while it is being written then it will only get what had been written at that point.

One option may be to use [man]file_get_contents[/man] and [man]file_put_contents[/man] to read and write the file; this will ensure that the two operations are handled atomically; if the writing is performed over a large part of the codebase, then using output buffering to collect the output before writing it would probably be easier (and possibly faster) than changing the code to build up a big string.
