what is @ in php?

[konfigure]

I have a generated code like this

 

x
$sSql = ew_BuildReportSql(EW_TABLE_SQL_TRANSFORM, $EW_TABLE_SQL_SELECT, $EW_TABLE_SQL_WHERE, EW_TABLE_SQL_GROUPBY, "", EW_TABLE_SQL_ORDERBY, EW_TABLE_SQL_PIVOT, $sFilter, @$sSort);

 

but I dont know what for is the "@", what is @ in php anyway?

The @ symbol can be used to suppress errors from showing, which usually isn't the best thing to do. In the code you posted it doesn't really look like thats how it's being used, I'm not aware of any other use for it.

I never use it. I think it makes for sloppy programming - its better to fix the code that is causing errors than it is to suppress the errors. If you leave the errors in the code, then your code isn't well written.

i believe the @ sign in your code suppressed the error so it wont cause error message in your function

so when the variable  @$sSort gets an error message it only passed empty value not the whole crapy warning message

i guess the $sSort  is your sql execution or .....

but that is no use  it should supressed the error right after it is passed in your var
