Rasmus Lerdorf (born 22 November 1968) is a Danish-Canadian[1] programmer. He co-authored and inspired the PHP scripting language, authoring the first two versions of the language and participating in the development of later versions led by a group of developers including Jim Winstead (who later created blo.gs), Stig Bakken, Shane Caraveo, Andi Gutmans, and Zeev Suraski. He continues to contribute to the project.

Early life and education[edit]

Lerdorf was born on Disko Island in Greenland and moved to Denmark in his early years.[2] Lerdorf's family moved to Canada from Denmark in 1980, and later moved to King City, Ontario in 1983.[3] 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.[4][5] He released the first version of PHP in 1995.[6]

Career[edit]

From September 2002 to November 2009 Lerdorf was employed by Yahoo! Inc. as an Infrastructure Architecture Engineer. In 2010, he joined WePay in order to develop their application programming interface.[7] Throughout 2011 he was a roving consultant for startups. On 22 February 2012 he announced on Twitter that he had joined Etsy.[8] In July 2013 Rasmus joined Jelastic as a senior advisor to help them with the creation of new technology.[9]

Lerdorf is a frequent speaker at Open Source conferences around the world. During his keynote presentation at OSCMS 2007, he presented a security vulnerability in each of the projects represented at the conference that year.[10]

Lerdorf also appeared at the WeAreDevelopers Conferences 2017 and 2019,[11] making a speech on the history of PHP, the new PHP 7 release in 2017, and the 25 years of PHP.[12]

Award[edit]

In 2003, Lerdorf was named in the MIT Technology Review TR100 as one of the top 100 innovators in the world under the age of 35.[13]
