Replace ProtocolPortNumber with the protocol and por t number that is to be blocked e.g. TCP 80. Replace InboundOutbound with either Inbound or Outbound depending on whether you want to block inbound or outbound traffice.

In a strong ly typed language, variables have an explicit type --- such as integer or string. PHP is a weakly typed language; the variable var bubble letter font 1 = 1.0 can be treated as an integer, a floating-point number if multiplied by a decimal, for instance or a string when concatenat ed with the . operator depending on how its used. PHP does very little variable checking, which is generally useful because it pro Bio Limousin Moteur de recherche vides additional flexibility and removes the need for casting. On the other hand, in certain circumstances, this can cause unexpec .

tring var1 initializes var2 as an explicit string. PHP also allows on-the-fly string casting by use of the strval function: the co de var3 = true creates var3 as a Boolean variable. strvalvar3 will treat that same Boolean variable as a string, such as in string comparisons or substring operations. String Comparisons Sometimes, PHPs weak typing can become a problem. For example, consider t he case of var1 = 1.0; var2 = 1;. A PHP comparison between the two treats them as equal: ifvar1 == var2 will return true, because font awesome icons by default PHP treats them as numbers. This remains true even they are wrapped in strval functions: ifstrvalvar1==strvalvar2 will also return true. To accurately compare these two strings in a PHP function, use the === comparison: ifvar1===var2 will return fal Bio Limousin Moteur de recherche se. Objects as Strings PHPs willingness to convert variables on-the-fly also can cause problems when using objects. For example, c .
