- The @-operator works only on expressions. A simple rule of thumb
- is: if you can take the value of something, you can prepend the @
- operator to it. For instance, you can prepend it to variables,
- function and <function>include</function> calls, constants, and
- so forth. You cannot prepend it to function or class definitions,
- or conditional structures such as <literal>if</literal> and
- <literal>foreach</literal>, and so forth.
+ Oper�tor @ pracuje pouze na v�razech. Plat� jednoduch� pravidlo:
+ m��ete-li z�skat hodnotu n��eho, m��ete p�ed to d�t oper�tor @.
+ To se t�k� nap��klad prom�nn�ch, funkc�, vol�n�
+ <function>include</function> konstant a podobn�. Nem��ete ho p�ed�adit
+ definic�m funkc� nebo t��d a podm�nkov�m struktur�m typu

- Currently the "@" error-control operator prefix will even disable
- error reporting for critical errors that will terminate script
- execution. Among other things, this means that if you use "@" to
- suppress errors from a certain function and either it isn't
- available or has been mistyped, the script will die right there
- with no indication as to why.

- PHP supports one execution operator: backticks (``). Note that
- these are not single-quotes! PHP will attempt to execute the
- contents of the backticks as a shell command; the output will be
- returned (i.e., it won't simply be dumped to output; it can be
- assigned to a variable).
