Your answer is correct, but I can't stand it when people put the two operands of the comparison operators in that order.

@Lucas: Surely that's just a matter of personal taste. What is your reasoning?

I'm with Lucas on this. My reasoning is that it doesn't make sense if you read it as an english sentence. "if zero does not equal the outcome of this function..."

It's evidently less readable. But there is a rationale for it in C-derived languages where you can accidentally write ‘if (a=0)’. ‘if (0=a)’ will get caught quickly. Though personally I don't use this style, it is a matter of taste and coding standards.

It is personal taste. I always use this notation and I find it more readable.

In mathematics, you always put the variable on the left and the quantity on the right. As a habit formed from that, I always follow Lucas's order.

I'll recommend a slight improvement over tom's
if (0 !== stripos($url, 'http://') && 0 !== stripos($url, 'https://')) { $url = 'http://' . $url; }
However, this will mess up links that use other protocols (ftp:// svn:// gopher:// etc)

A:
if (!preg_match("/^http:\/{2}/",$url)){
$url = 'http://' . $url;
}

A:
I would check for the some letters followed by a colon. According to the URI specifications a colon is used to separate the "schema" (http, ftp etc.) from the "schema specific part". This way if somebody enters (for example) mailto links these are handled correctly.
