请问怎么去掉数组里面所有值两边的空格

回复讨论(解决方案)

trim()

$a = array(  ' a', ' b ', 'c ',  array(' a', ' b ', array(' a', ' b ', 'c '),),);array_walk_recursive($a, function(&$v) { $v = trim($v); });var_export($a);

array (  0 => 'a',  1 => 'b',  2 => 'c',  3 =>   array (    0 => 'a',    1 => 'b',    2 =>     array (      0 => 'a',      1 => 'b',      2 => 'c',    ),  ),)
