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



gzread — Read a specified length of a compressed file.


string gzread(zp, Length);
int zp: File pointer
int Length: Number of bytes to read


Uncompressed string on success or NULL on error


If the file pointer is set to write this function returns an empty string. This function is slightly different from gzgets() in that gzread() returns the contents of a file up to a specified length or EOF which ever comes first. Reaching a new line does not halt output. As a companion to gzwrite(), this function is able to read binary files.


PHP 3, PHP 4 >= 4.0b1


Example 1456. Read a compressed file

$string = "Hello Compressed world";
$gz = gzopen("myfile.gz","r");
$string = gzread($gz, 1024);
