#24677 [Asn->Fbk]: [PEAR] File::readAll() does not close file handle after reading

I have just come accross this myself. I tried the patch too with no success. ------------------------------------------------------------------------ [2003-09-30 13:40:26] pmjones at ciaweb dot net Sorry to take so long to get back to you. Applied the patch, does not appear to work. Using File::readAll() on a file the first time gives a notice "Undefined variable 'lock' at line 360 in File.php'" but reads the file OK. Using it subsequently on the same file, it goes into an infinite loop with "WARNING [feof(): 7 is not a valid File-Handle resource] in file [/usr/local/ share/pear/File.php] at line [209]". ------------------------------------------------------------------------ [2003-07-31 04:24:57] nicos@php.net That should fix it?

I think this is because readAll() does not close the file handle when the method is complete (it leaves the file handle open, thus locking the file off from subsequent access). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24677&edit=1
