详解PHP如何使用str_replace替换多维数组

$a = array( 'a' => 'bdc#', 'ceshi' => array('c'=>array('f'=>'#')) ); $a = str_replace('#', 'ccc', $a); var_dump($a);

array (size=2) 'a' => string 'bdcccc' (length=6) 'ceshi' => array (size=1) 'c' => array (size=1) 'f' => string '#' (length=1)

$a = array( 'a' => 'bdc#', 'ceshi' => array('c'=>array('f'=>'#')) ); function strReplace(&$array) { $array = str_replace('#', 'ccc', $array); if (is_array($array)) { foreach ($array as $key => $val) { if (is_array($val)) { strReplace($array[$key]); } } } } strReplace($a); var_dump($a);

array (size=2) 'a' => string 'bdcccc' (length=6) 'ceshi' => array (size=1) 'c' => array (size=1) 'f' => string 'ccc' (length=3)
