By default, the PHP instruction MAGIC_QUOTES_GPC is on, and it automatically runs Addslashes () for all get, POST, and COOKIE data. Do not use Addslashes () on strings that have been escaped by MAGIC_QUOTES_GPC, because this can result in a double escape. You can use the function GET_MAGIC_QUOTES_GPC () for instrumentation when this situation is encountered. Example 1. Addslashes () example The code is as follows Copy Code ?$str = "Is your name o #39;

' is operated, the index of the original database can be changed;In the second segment, B points to a string, which is non-mutable. Therefore, after B = 'xxx' is operated, the pointer B changes itself and points again to another memory space, the memory address in the Tup tuples (the former B) indicates that the space is not changed, or the string is '123 '.Therefore, Tup is always non-Immutable in the first or second segment, and the change is also a change in the memory pointed to by its eleme

Python From types import stringtype, unicodetype If isinstance (OBJ, stringtype) or \ Isinstance (OBJ, unicodetype ): The fact that the empty list is false is used for the sequence (string, list, And tuples), so "if not seq" or "If seq" is greater than "If Len (SEQ) "or" If not Len (SEQ. Do not rely on meaningful trailing spaces when writing string text. This rear space is visually unrecognizable, and some editors (especially recently, reindent. py) will trim them. D

Python learning 3 --- sequence, list, tuples, python ---I. Sequence 1.1 sequence Concept The most basic data structure in pythn is sequence ). Each element in the sequence is assigned a sequence number-element index. The first index is 0, the second is 1, and so on. Similar to the subscript In arrays and collections in JAVA. From the back to the front, the last index is-1,-2 ,.... Python contains six built-in sequences. The list and metadata are the t

Before taking this course, a lot of small partners told me: "Don't choose Python, this course is difficult." "I didn't agree with what they said, but I didn't dare to deny it, because it was really hard to learn C and MATLAB. So, I hesitated. But perhaps the desire for credit (this elective is more than one point ...). , I have a bite to report this seems to be a difficult elective.However, things are not as bad as they thought, the first lesson of the school is very relaxed and happy, and for P
