When to use echo vs. print?

tsweezey

I've been largely using php over the last year or so mostly to modify existing applications, but now that I'm coding my own, I have a question regarding appropriate usage.

First, I currently "echo" everything, as largely, I simply don't understand the benefits that "print" provides. I know I'm being a coding misfit, but I just dont' know any better. Can someone enlighten me as to when it's best to use echo vs print? Perhaps the advantages of one vs. the other.

Also, I have a project where I'm trying to modify what shows in the browsers url window... Is this possible?

Basically, it's for an affiliate type application where "SiteA" clicks a link to "SiteB" and the url address for site "B" still reflects that of "A".

Site B would be "my" site, whereas, Site A is the affiliates site.

Thanks in advance.

Best Regards,

Tim

On your second problem:

How about using frames for this? A frameset with topframe having 0 pixels height, bottom 100%.

Pardon my "newbieness" and complete cluelessness regarding frames... but wouldn't I need to have control over SiteA to setup the frames? Site a is the affiliate site, and all they'll do is to post a link.

Everything that I code would have to be on SiteB. Does that make sense?

Thanks again,

About echo vs. print. They're essentially the same, except print returns a value (boolean). Echo can output more than 1 var too. Although, I don't know why you'd ever use this feature.


$var = print("set the var"); 
// Outputs "set the var" and $var is now equal to 1 

$var = echo("set the var");
// parse error

echo "$var", " something else"; 
// outputs "1 something else"

print "$var", " something else"; 
// parse error 

print "$var something else";
// outputs "1 something else"

I personally use echo for everything, but there may be some cases where print would have an advantage (if you wanted to do error checking for example).

Yah, I use echo for 99% of things.

i use modifications of print sometimes
for example
print_r() to output all the values of an array
