Programming PHP

sql_regcase
string sql_regcase(string match)
Creates and returns a regular expression pattern that matches match, ignoring case. The
resulting pattern contains each character in match in each case; for example, given
“O’Reilly”, the function returns “[Oo][’] [Rr][Ee][Ii][Ll][Ll][Yy]”.
sqrt
double sqrt(double number)
Returns the square root of number.
srand
void srand(int seed)
Seeds the standard pseudorandom-number generator with seed. You should call this
function with a varying number, such as that returned by time( ), before making calls to
rand( ).
sscanf
mixed sscanf(string string, string format[, mixed variable1 ...])
Parses string for values of types given in format; the values found are either returned in an
array or, if variable1 through variableN (which must be variables passed by reference) are
given, in those variables.
The format string is the same as that used in sprintf( ). For example:
$name = sscanf("Name: k.tatroe", "Name: %s"); // $name has "k.tatroe"
list($month, $day, $year) = sscanf("June 30, 2001", "%s %d, %d");
$count = sscanf("June 30, 2001", "%s %d, %d", &$month, &$day, &$year);
stat
array stat(string path)
Returns an associative array of information about the file path. Ifpath is a symbolic link,
information about the file path references is returned. See fstat for a list of the values
returned and their meanings.
