Question

我有一个从0到n的键的数组，我需要在迭代数组时使用continue来排除以下键模式：

... 3,4,8,9,13,14,18,19

问题是我需要某种公式，以便模式不仅限于上面的数字。

Answer 1

$exclude = array(3,4,8,9,13,14,18,19);
foreach ( $inputArray as $key => $value ) {
  if ( in_array($key, $exclude) ) {
    continue;
  }

  // do something
}

Answer 2

$array = range( 0, $n);
foreach( $array as $i)
{
    if( in_array( $i, array( 3,4,8,9,13,14,18,19)))
        continue;
}

Answer 3

$exclude_keys = array(3,4,9);

for($array as $index => $value) {
    if(false !== array_search($index, $exclude_keys)) {
        //do what you want
    }
}

Answer 4

$exclude_mods = array(3,4,8,9);
foreach ( $inputArray as $key => $value ) {
  if ( in_array($key % 10, $exclude) ) {
    continue;
  }

  // do something
}

使用continue从数组中排除键
