Rasmus Lerdorf (born 22 November 1968),who created the PHP scripting language, is a Greenlandic programmer with Canadian citizenship, authoring the first two versions of the language and participated in the development of later versions led by a group of developers including Jim Winstead (who later created blogs), Stig Bakken, Shane Caraveo, Andi Gutmans and Zeev Suraski. He continues to contribute to the project.
Beginning of Life and his Studies
His family moved to Canada from his native Greenland, in 1980, and later moved to King City, Ontario in 1983.He graduated from King City Secondary School in 1988, and in 1993 he graduated from the University of Waterloo with a Bachelor of Applied Science in Systems Design Engineering. He contributed to the Apache HTTP Server and he added the LIMIT clause to the MSQL DBMS. A variant of this LIMIT clause had already been around for a decade in mainframe relational database management systems (like Oracle Rdb running on VAX/VMS, formerly from Digital Equipment Corporation), but apparently it had not yet been picked up by the emerging PC-based databases. It was later adapted by several other SQL-compatible DBMS.

From September 2002 to November 2009 he was employed by Yahoo! Inc. as an Infrastructure Architecture Engineer. In 2010, he joined WePay in order to develop their application programming interface.Throughout 2011 he was a roving consultant for startups. On 22 February 2012 he announced on Twitter that he had joined Etsy.In July, 2013 Rasmus joined Jelastic as a senior advisor to help them with the creation of new technology.
