# 1. Run Thrift to generate the php module HBase

# thrift --gen php ../../../src/main/resources/org/apache/hadoop/hbase/thrift/Hbase.thrift
|
2008-09-11 16:12:52 -04:00
|
|
|
# 2. Modify the import string below to point to {$THRIFT_HOME}/lib/php/src.
|
|
|
|
|
# 3. Execute {php DemoClient.php}. Note that you must use php5 or higher.
