undefined type of a variable
no learned functions

if the array is changed, the behavior of this function is undefined.
if the array that array_walk() is applied to is changed, the behavior of this function is undefined, and unpredictable.

everytime an undefined class should be instanciated, it 'll be called.
also note that the directive unserialize_callback_func directive became available in php 4.2.0.

qlibrary:: resolve_ sys: symbol "% 1" undefined in% 2 (% 3)
cannot resolve symbol "%1" in %2: %3

for this reason, as of php 3.0.12 and php 4.0b3-rc4, the result of this automatic conversion is considered to be undefined.
php 4 introduced the new curly bracket syntax to access characters in string, use this syntax instead of the one presented above:
