What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



gzopen — Opens or creates a gzip file of the specified file name.


int gzopen(filename, Mode[, use_include_path]);
string filename: File to open or create
string Mode: File mode
int use_include_path (optional): Search the include path for the file


File pointer on success or FALSE on error


If the file is opened or created successfully, a file identifier is returned which can be passed to other gz functions. The file mode is similar to that for fopen() but with several significant differences. Parameters commonly used in the GNU gzip program can also be incorporated in the file mode. You should view any gzip Unix man page for more details. For example w - write to a file r - read from a file w9 - write to a file with compression level set to 9 w9f - write filtered data with a compression level of 9 w9fh - write filtered data with a compression level of 9 with Huffman compression. If use_include_path is set to TRUE the function also searches the include path for the file specified.


PHP 3, PHP 4 >= 4.0b1


Example 1453. Create a compressed file

$gz = gzopen("myfile.gz","w9");
gzputs ($gz,"Hello compressed world!");
