how do you use the @

[Anon]

hi

i know the @ in perl is used for arrays and i assume it is the same in php but am not sure how to use it. for example pg_pconnect (function to connect to a postgres database) returns a handle to the connection right? but what does this mean @pg_pconnect? i have some code that i have to work with which uses this syntax, but i dont understand it. also the code also has things like @@, if(!@) etc. can anyone help?

thanks

The @ symbol suppresses any error message that may occur. For example, if your connection to the database failed, the @ symbol would stop PHP throwing an error and allows for your own error checking.

The !@ means not I think, so you could write

if(!@pg_connect){
echo"an error";
}else {
do database stuff
}

I hope this makes sense.

Cheers,

P.S. @ signs are not arrays in php, you assign all types of variable with $variablename.

I read your reply but I would like to know what does the @@ stand for?

And also I have seen !@ been used without any reference to any function. Any ideas?
