<code>如何将 $format 传入到 array_map 当中 </code>
<code> return array_map(function ($time) use ($format) { return date($format, $time); }, range(strtotime($hisStart), strtotime($hisEnd), $range)); </code>
关键字:闭包
最优解当然是像 @picasso250 一样用use了
<code> return array_map(function ($t) use ($f) { return date($f, $t); }, range(strtotime($s), strtotime($e), $r)); </code>
如果用不了use关键字的话低版本的话还可以用global:
<code>$format = "H:i:s"; function fm($t){ global $format; return date($format, $time); } array_map('fm', range(strtotime($hisStart), strtotime($hisEnd), $range)); </code>
当然用Class写这个也是可以的,就是看起来特别麻烦...
<code>Class hisRange { public $s, $e, $r, $f; function __constructor($s= '00:00:00', $e= '23:59:59', $r= 3600, $f= 'H:00:00') { $this->s = strtotime($s); $this->e = strtotime($e); $this->r = $r; $this->f = $f; } function run() { return array_map(array($this, 'fm'), range($this->s, $this->e, $this->r)); } function fm($t) { return date($this->f, $t); } } $range = new hisRange(); $s = $range->run(); </code>
好吧,我大概只是来提供不同的解法的...
