searching within a document

[johnsworld]

i'm trying to create a script which opens an external url and searches within in the document for a given keyword, returning true if found.

i am thinking of using fread(URL), but am stuck for the most efficient way of finding the keyword within the string. another option would be the file(URL) method and then searching each element of the array.

can anyone advise as to which is the best method to do this.

thanks

Some variant of the method this thread would perhaps be best. You sound like you've got it easier, 'cos you're looking for a literal words rather than a whole regexp pattern (saying substr()!==false is faster and less hassle than preg_match()).

brilliant, thanks Weedpacket, it looks as though i'll find what i'm looking for somewhere in there.
