Did yahoo use php for making their search engine ? Can php be used for more complicated web applications such as search engine and still work fast ?
Thanks

nope, php is a scripting language, meaning it needs to be intrepreted before it can be run. If Yahoo handles its queries with php scripts as its search engine, it would need a tremendous amount of computing power to run Yahoo. So it is more likely that Yahoo uses a compiled code (normal executables), which is much faster to run and easier on the processor.
It is possible for Yahoo to handle it's other things with php or similar technologies, but certainly, not it's search engine.
Note: it is possible to create a small scale search engine with PHP, but it is fairly impossible to expand it into large scale search engine like Yahoo or Google without an unlimited amount of computing power.

PHP and JAVA are too slow, Although, theoretically they could have a special (and secret) native optimized compiler fot java code - unlikely. They are probably using a mix of languages (PHP?, Java, C++) but with C at the most critical parts, and re-wring from the other languages to C all the time. Probably yahoo does the same. I bet microsoft (bing) uses C# which, is more or less equivalent to C/C++, and/or Visual Basic. The most recent versions of Microsoft Visual Basic are very powerful and fast.
