php根据一个给定范围和步进生成数组的方法,php给定步进数组
这里给定开始和结束值,再给定一个步进值,就可以生成一个等差数组。
function array_range($from, $to, $step=1){
$array = array();
for ($x=$from; $x <= $to; $x += $step){
$array[] = $x;
}
return $array;
}
print_r(array_range(0, 20, 5));
/*
returns:
Array
(
[0] => 0
[1] => 5
[2] => 10
[3] => 15
[4] => 20
)
*/
希望本文所述对大家的php程序设计有所帮助。
