gzdecode() insufficient memory - size is exhausted

Do you know any solucion to unpack large .gz in php (>200 MB .gz, >4GB original... maybe in packs of >1GB or >2GB inside) ?

Solucion of decode .gz part by part is needed.

Code gzdecode(@file_get_contents($file))

gets PHP error:

PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate ...

of course.

I cannot increase the PHP memory limit of the webserver, and it seems to be no point in trying while data >>1GB.

Using inflate_add() isn't solution, it generates the same "PHP Fatal error: Allowed memory size ... exhausted ...".

Any idea? (I found no answers in 1, 2 etc.)

came right here, my error might be different, but Google showed this page first. so for anyone coming here:

'gzdecode(): insufficient memory'

In my case this was due to a wrongly placed boolean that told gzdecode the length of decoding would be 1.

Use gzopen() instead of gzdcode(). Then you can read small chunks at a time with gzread().
