PHP多维数组转一维数组的简单实现方法_PHP
本文实例讲述了PHP多维数组转一维数组的简单实现方法。分享给大家供大家参考,具体如下:
php语言本身没有将多维数组转为一维数组的函数,但是我们可以自己写一个php函数来实现将多维转一维的功能。
运用了递归,简单粗暴,整个函数体9行代码就实现了该功能,php源码如下:
$multi = array( array( array( 'wo', 'shi' ), 'php' ), 'cheng', array( array( 'xu', 'yuan', ) ), '!' ); $multi = arrToOne($multi); print_r($multi); function arrToOne($multi) { $arr = array(); foreach ($multi as $key => $val) { if( is_array($val) ) { $arr = array_merge($arr, arrToOne($val)); } else { $arr[] = $val; } } return $arr; }
执行后的效果:
Array ( [0] => wo [1] => shi [2] => php [3] => cheng [4] => xu [5] => yuan [6] => ! )
希望本文所述对大家PHP程序设计有所帮助。
