First, every string must be checked over for escaped characters and such - not only those within double quotes. Second, the opcode for double quotes differ only if they contain variables: http://blog.libssh2.org/index.php?/archives/28-How-long-is-a-piece-of-string.html and anyway, the microseconds you could win with this really don't count that much to be worth the effort... find real bottlenecks and optimize against those. greets Zoltán Németh > ashish.sharma wrote: > > Hello All, > > > > I am working on PHP from quite some time.
