We all know that PHP is a very good dynamic web page development language (fast speed, short development cycle ......). However, only a few people realize that PHP can also be a good language for writing Shell scripts. When PHP is used as a language

Generally, we will write as follows:Copy codeThe Code is as follows:If ($ _ GET ['time'] = null){$ Time = time ();}Else{$ Time = $ _ GET ['time'];}Echo $ time;// If GET has time, the variable time is included. If not, the current time () time is

The most commonly used non-Array in PHP does not belong to. How is Array implemented? In PHP, the internal Array is implemented through a hashtable, And the hash conflict is solved using the link method. In this case, the complexity of searching

Search for a specific value in the array. If yes, return TRUE. Otherwise, return FALSE.Boolean in_array (mixed needle, array haystack [, boolean strict])Find a specified key in the array. If yes, return TRUE. Otherwise, return FALSE.Boolean
