The for statement is the most basic statement in the loop control part of PHP (also multiple languages). The execution rules and basic usage of the for statement are not described here, you can refer to the PHP Manual for statements section to define its syntax as follows: For (expr1; expr2; expr3) Statement The following describes several useful variants of the for statement. 1. infinite loop The first is an infinite loop (also known as an "endless loop "). The null expression is effective in s

The most common function of leaving expr1 blank is to complete more complex initialization. If (isset ($ I )){ Unset ($ I ); If (int) date ('') $ I = 0; } Else { $ I = 1; } } Else { $ I =

, add conditions for terminating loops when using infinite loops.

following example where they all show numbers 1 to 10: /* Example 1 */ For ($ I = 1; $ I Echo $ I;} /* Example 2 */ For ($ I = 1; $ I ){If ($ I> 10 ){Break;}Echo $ I;} /* Example 3 */ $ I = 1;For (;;){If ($ I> 10 ){Break;}Echo $ I;$ I;} /* Example 4 */ For ($ I = 1; $ I ?> Of course, the first example seems to be the most normal (or fourth), but users may find it convenient to use null expressions in a for loop in many cases. PHP also supports the replacement syntax of the for loop with colon

network. We know that the IP protocol used by the network layer can help us to locate the target host based on the IP address, but there may be multiple applications running on one host, and how to communicate with the specified application is specified by the TCP or UPD address, or the port number. This makes it possible for a Socket instance to uniquely represent a communication link for an application on a host.WebSocket, however, is a complete application-layer protocol that contains a set

method is to recycle the file-related memory, and one is to swap the anon portion of memory (that is, the allocated memory) to the swap partition.One of the purposes of Linux memory usage is to use memory as much as possible. When the file is read and written, the file's cache will remain in the system memory, until the memory is not enough time, there is no active release of this part of the memory logic. This allows you to read the cached file directly from memory the next time you read it, w
