------ Solution --------------------

PHP code

$ Arr = array (,); $ counter = 1; for ($ I = 0; $ I <count ($ arr) -1; $ I ++) {if ($ arr [$ I + 1] ==$ arr [$ I] + 1) {$ counter ++; if ($ counter = 3) {echo"
Find the number of the continuous value: \ n [". ($ I-1 ). "] =>{$ arr [$ I-1]} \ n [". $ I. "] =>{$ arr [$ I]} \ n [". ($ I + 1 ). "] =>{$ arr [$ I + 1]} \ n
";}} Else $ counter = 1 ;}
