PHP uses an array to implement the queue (in fact, first-out how to implement)

PHP uses arrays to implement queues (in fact, FIFO)

the array handler function of PHP can also implement queues for arrays, which are "advanced and out". In the stack, the last data pressed (into the stack) will be ejected first (out of the stack). And the queue is FIFO, just like the bank's automatic arranging machine.

PHP uses arrays as a stack, mostly using Array_push () and Array_pop () two system functions. The main use of the Array_push () function is to add one or more elements to the end of the first parameter's array, and then return the length of the new array, as shown in the following example:

in PHP, the array is considered as a queue and is mainly implemented with Array_push () and Array_shift ().
Copy the Code code as follows:

$zhan =array ("WEB");//declaring an array as a queue
Array_push ($zhan, "PHP");//Press the string into the stack (array)
Array_push ($zhan, "WWW.CHHUA.COM");//press into an element again
Print_r ($zhan);//print array contents
?>

The stack is mainly using the Array_shift () function to eject the first element of the array and reduce the length of the array by 1, as shown in the following example:
Copy the Code code as follows:

$zhan =array ("Web", "www.chhua.com", "Web Development note", "PHP", "website building");//Declare an array as a stack
Array_shift ($zhan);//String out of the queue (array)
Print_r ($zhan);//printing array contents Array ([0] = web[1] = www.chhua.com[2] + WEB Development Note [3] = PHP)
?>
