compilation overhead. 28, try to do the cache, you can use memcached. Memcached is a high-performance memory object caching system that can be used to speed up dynamic Web applications and reduce database load. It is useful to cache the operation Code (OP code) so that the script does not have to recompile for each request. 29. When manipulating strings and having to check whether their lengths meet certain requirements, you will of course use the strlen () function. This function executes fa

matches a character only when it is not followed by a specific character. When performing operations such as forward-looking and negative-looking, the regular expression engine pays attention to the part after the string, but does not move the index//forward-looking re =/([a-z]+ (? =\d))/I; We're going to match the word followed by a number, and then return the word without returning the number str ="ABC every1 ABC"; Alert (Re.test (str));//true alert (regexp.$1);//every alert (Re.lastindex);/

The array in PHP is actually an ordered map. A map is a type that associates values to the keys. This type is optimized in many ways, so it can be used as a real array, or as a list (vector), a hash (an implementation of a mapping), a dictionary, a collection, a stack, a queue, and more possibilities. Because the value of an array element can also be another array, the tree structure and the multidimensional array are also allowed.Role:1, management and operation of a set of data, data can be an
