The set_time_limit() function and the configuration directive max_execution_time only affect the execution time of the script itself. Notas. fwrite() ) The wrapper used in from stream, length The file must be accessible to PHP, so you need to ensure that the file access permissions allow this access. Nota: . If you attempt to read using the file handle you will get the binary directory contents.

If you have a CLI script that prompts you for a password via STDIN, and you need to run it from PHP, proc_open() can get you there. Seems not documented here but keep in mind, when $filename contains null byte (\0) then a TypeError will be thrown with message such; when using ssl / https on windows i would get the error: Human Language and Character Encoding Support, Extensiones relacionadas con el sistema de ficheros, ftp://blossom:[email protected]//var/school/bubbles.txt, https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=164700, http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85.
