// ----- Constants
define( 'PCLZIP_READ_BLOCK_SIZE', 2048 );
// ----- File list separator
// In version 1.x of PclZip, the separator for file list is a space
// (which is not a very smart choice, specifically for windows paths !).
// A better separator should be a comma (,). This constant gives you the
// abilty to change that.
// However notice that changing this value, may have impact on existing
// scripts, using space separated filenames.
// Recommanded values for compatibility with older versions :
//define( 'PCLZIP_SEPARATOR', ' ' );
// Recommanded values for smart separation of filenames.
define( 'PCLZIP_SEPARATOR', ',' );
// ----- Error configuration
// 0 : PclZip Class integrated error handling
// 1 : PclError external library error handling. By enabling this
// you must ensure that you have included PclError library.
// [2,...] : reserved for futur use
define( 'PCLZIP_ERROR_EXTERNAL', 0 );
// ----- Optional static temporary directory
// By default temporary files are generated in the script current
// path.
// If defined :
// - MUST BE terminated by a '/'.
// - MUST be a valid, already created directory
// Samples :
// define( 'PCLZIP_TEMPORARY_DIR', '/temp/' );
// define( 'PCLZIP_TEMPORARY_DIR', 'C:/Temp/' );
