Use the loop
Wang students need to repeatedly back and forth to Beijing and Dalian, it is a typical cycle structure. Wong Sze assume a total investment of this project need to travel Dalian 100 times per round are the king of the students will be counted once. Do we write the same code a hundred times? Clearly it can not deal with such a high IQ for programmers.
We abstract the human kind of thinking. We define a loop structure Wuxi marble measurement platform
? <PHP
// define the required number of round-trip, foreigners prefer to start counting from zero, we have to start from zero count
$ count = 0;
behind // while connected to a Boolean value judgment, execution is true, false stop
// $ count less than 100 when executed, i.e. $ count is 0-99 when executed
// if $ count is not less than 100, the circulation is stopped to perform subsequent code
// at the beginning of the cycle
the while ($ count <100) {
echo 'I am a king always thinking, my first business trip /> <br '' $ count.. ';
// for each execution make $ count + 1, this is the case, it will not always generate $ count is less than 100, the
$ count ++;
/ / cycle ends
}
echo 'of the succeeding code';
?>
We can make up for some specialized code loop logic diagram for the while:
