导读:我有一个名为$mydata的数组,如下所示: Array([0] = Array ( [id] = 1282 [type] =2 )[1] = Array ( [id] = 1281 [type] =1 )[2] = Array ( [id] = 1266 [type] =2 )[3] = Array ( [id] = 1265 [type] =3 )) 我已将数组分配给smarty $smarty- assign(“resul
我有一个名为$mydata的数组,如下所示:
Array ( [0] => Array ( [id] => 1282 [type] =>2 ) [1] => Array ( [id] => 1281 [type] =>1 ) [2] => Array ( [id] => 1266 [type] =>2 ) [3] => Array ( [id] => 1265 [type] =>3 ) ) 我已将数组分配给smarty $smarty-> assign(“results”,$mydata) 现在,在模板中,我需要打印数组中每个“类型”的数量.任何人都可以帮我这样做吗?
PHP 5.3,5.4:
从Smarty 3开始,你可以做到 {count($mydata)} 你也可以在Smarty 2或3中管它: {$mydata|count} 要计算“类型”值,您必须在PHP或Smarty中遍历数组: {$type_count = array()} {foreach $mydata as $values} {$type = $values['type']} {if $type_count[$type]} {$type_count[$type] = $type_count[$type] + 1} {else} {$type_count[$type] = 1} {/if} {/foreach} Count of type 2: {$type_count[2]} PHP 5.5: 使用PHP 5.5和Smarty 3,您可以使用新的array_column函数: {$type_count = array_count_values(array_column($mydata,'type'))} Count of type 2: {$type_count['2']} (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
