Question

我在PHP中有一个打印这个

的函数

Array ( [ladygaga] => 2 [marcus] => 1 [brigstocke] => 1 [georgejeie] => 1 [george] => 1 [dbeckham] => 1 [becks] => 1 ) 1

如何提取单词字符串？也就是说，我想收集每个单词的单个字符串，这样我就可以单独调用每个单词，如“lady gaga”，“marcus”等......然后我将这些单词分配给html参数

谢谢

Answer 1

尝试array_keys提取密钥：

$strings = array_keys($theArray);

// Gives:

array('ladygaga', 'marcus', 'brigstocke', ...);

Answer 2

查看array_keys()

$array = array(0 => 100, "color" => "red");
print_r(array_keys($array));

// returns Array(0, "color");

Answer 3

像这样使用array_keys

$array = Array ( [ladygaga] => 2 [marcus] => 1 [brigstocke] => 1 [georgejeie] => 1 [george] => 1 [dbeckham] => 1 [becks] => 1 ) ;

$keys  = array_keys($array); // This will contain "ladygaga", "marcus" .. as elements

Answer 4

如果你要做的就是单独调用单词，那么你可能想看看PHP的foreach循环。请查看此处的文档：http://php.net/manual/en/control-structures.foreach.php

您只需按键并忽略值：

foreach (array_expression as $key => $value)
statement

数组中的PHP字符串
