  • Variable Feature Usage Patterns in PHP

    Variable Feature Usage Patterns in PHP

    Variable Feature Usage Patterns in PHP Mark Hills East Carolina University, Greenville, NC, USA [email protected] Abstract—PHP allows the names of variables, classes, func- and classes at runtime. Below, we refer to these generally as tions, methods, and properties to be given dynamically, as variable features, and specifically as, e.g., variable functions expressions that, when evaluated, return an identifier as a string. or variable methods. While this provides greater flexibility for programmers, it also makes PHP programs harder to precisely analyze and understand. The main contributions presented in this paper are as follows. In this paper we present a number of patterns designed to First, taking advantage of our prior work, we have developed recognize idiomatic uses of these features that can be statically a number of patterns for detecting idiomatic uses of variable resolved to a precise set of possible names. We then evaluate these features in PHP programs and for resolving these uses to a patterns across a corpus of 20 open-source systems totaling more set of possible names. Written using the Rascal programming than 3.7 million lines of PHP, showing how often these patterns occur in actual PHP code, demonstrating their effectiveness at language [2], [3], these patterns work over the ASTs of the statically determining the names that can be used at runtime, PHP scripts, with more advanced patterns also taking advantage and exploring anti-patterns that indicate when the identifier of control flow graphs and lightweight analysis algorithms for computation is truly dynamic. detecting value flow and reachability. Each of these patterns works generally across all variable features, instead of being I.

    Strings String Literals String Variables Warning!

    Strings String literals • Strings are not a built-in data type. char *name = "csc209h"; printf("This is a string literal\n"); • C provides almost no special means of defining or working with strings. • String literals are stored as character arrays, but • A string is an array of characters you can't change them. terminated with a “null character” ('\0') name[1] = 'c'; /* Error */ • The compiler reserves space for the number of characters in the string plus one to store the null character. 1 2 String Variables Warning! • arrays are used to store strings • Big difference between a string's length • strings are terminated by the null character ('\0') and size! (That's how we know a string's length.) – length is the number of non-null characters • Initializing strings: currently present in the string – char course[8] = "csc209h"; – size if the amount of memory allocated for – char course[8] = {'c','s','c',… – course is an array of characters storing the string – char *s = "csc209h"; • Eg., char s[10] = "abc"; – s is a pointer to a string literal – length of s = 3, size of s = 10 – ensure length+1 ≤ size! 3 4 String functions Copying a string • The library provides a bunch of string char *strncpy(char *dest, functions which you should use (most of the char *src, int size) time). – copy up to size bytes of the string pointed to by src in to dest. Returns a pointer to dest. $ man string – Do not use strcpy (buffer overflow problem!) • int strlen(char *str) – returns the length of the string. Remember that char str1[3]; the storage needed for a string is one plus its char str2[5] = "abcd"; length /*common error*/ strncpy(str1, str2, strlen(str2));/*wrong*/ 5 6 Concatenating strings Comparing strings char *strncat(char *s1, const char *s2, size_t n); int strcmp(const char *s1, const char *s2) – appends the contents of string s2 to the end of s1, and returns s1.

It targets the C# language and is a .NET Roslyn live analyzer providing live analysis feedback to the developers using it. ReDi uses principles from formal specification and symbolic execution to implement methods for performing domain restriction on variables, parameters, and return values. A domain restriction is an invariant implemented as a check function, that can be applied to variables utilizing an annotation referring to the check method. ReDi can also help to prevent runtime exceptions caused by null pointers. ReDi can prevent null exceptions by integrating nullability into the domain of the variables, making it feasible for ReDi to statically keep track of null, and de- tecting variables that may be null when used. ReDi shows promising results with finding inconsistencies and faults in some programming projects, the open source CoreWiki project by Jeff Fritz and several web service API projects for services offered by Innovation Norway.

    Strings String Literals Continuing a String Literal Operations on String

    3/4/14 String Literals • A string literal is a sequence of characters enclosed within double quotes: "When you come to a fork in the road, take it." Strings • String literals may contain escape sequences. • Character escapes often appear in printf and scanf format strings. Based on slides from K. N. King and Dianna Xu • For example, each \n character in the string "Candy\nIs dandy\nBut liquor\nIs quicker.\n --Ogden Nash\n" causes the cursor to advance to the next line: Bryn Mawr College Candy CS246 Programming Paradigm Is dandy But liquor Is quicker. --Ogden Nash Continuing a String Literal How String Literals Are Stored • The backslash character (\) • The string literal "abc" is stored as an array of printf("When you come to a fork in the road, take it. \ four characters: --Yogi Berra"); Null o In general, the \ character can be used to join two or character more lines of a program into a single line. • When two or more string literals are adjacent, the compiler will join them into a single string. • The string "" is stored as a single null character: printf("When you come to a fork in the road, take it. " "--Yogi Berra"); This rule allows us to split a string literal over two or more lines How String Literals Are Stored Operations on String Literals • Since a string literal is stored as an array, the • We can use a string literal wherever C allows a compiler treats it as a pointer of type char *. char * pointer: • Both printf and scanf expect a value of type char *p; char * as their first argument.
