在数组中计算字符串的出现次数 [英] Count string occurrences in array

问题描述

有没有人知道如何计算这个数组中的照片的发生情况：

  Array（
 [ 0] => stdClass Object（[type] => photo [id] => 1404781893036 [created_time] => 2012-03-02T07：58：23 + 0000）
 [1] => stdClass Object（[type] => photo [id] => 14047818930362 [created_time] => 2012-03-01T14：58：53 + 0000）
 [2] => stdClass Object ] => status [id] => 1404781893036 [created_time] => 2012-03-01T09：49：40 + 0000）
 [3] => stdClass对象（[type] => [id] => 14047818930362 [created_time] => 2012-03-01T09：36：04 + 0000）
 [4] => stdClass Object（[type] => photo [id] => ; 14047818930362 [created_time] => 2012-02-28T07：03：25 + 0000）
 [5] => stdClass对象（[type] => photo [id] => 1404781893036 [created_time] => 2012-02-27T09：15：34 + 0000）
 [6] => stdClass Object（[type] => photo [id] => 14047818930362 [created_time] =&g吨; 2012-02-27T07：32：13 + 0000）
 [7] => stdClass Object（[type] => status [id] => 1404781893036 [created_time] => 2012-02-25T09：36：57 + 0000）
 [8] => stdClass Object（[type] => photo [id] => 1404781893036 [created_time] => 2012-02-23T08：46：43 + 0000）
 [9] => stdClass Object（[type] => status [id] => 1404781893036 [created_time] => 2012-02-22T21：04：30 + 0000）
 [10] => stdClass Object（[type] => status [id] => 1404781893036 [created_time] => 2012-02-21T20：38：27 + 0000）
 [11] => stdClass Object（[type] => photo [id] => 1404781893036 [created_time] => 2012-02-21T07：22：44 + 0000）
 [12] => stdClass Object（[type] => status [id] => 14047818930362 [created_time] => 2012-02-20T08：32：46 + 0000）
 [13] => stdClass Object（[type] => status [id] => 1404781893036 [created_time] => 2012-02-17T15：00：11 + 0000））
  

我是一个PHP新手，并且挣扎着这个。

解决方案

pre> $ count = 0;
foreach（$ array as $ item）{
if（$ item-> type ==='photo'）{
$ count ++;
}
}


Does anyone know how to count the occurrences of "photo" in this array:

    Array ( 
    [0] => stdClass Object ( [type] => photo [id] => 1404781893036 [created_time] => 2012-03-02T07:58:23+0000 ) 
    [1] => stdClass Object ( [type] => photo [id] => 14047818930362 [created_time] => 2012-03-01T14:58:53+0000 ) 
    [2] => stdClass Object ( [type] => status [id] => 1404781893036 [created_time] => 2012-03-01T09:49:40+0000 ) 
    [3] => stdClass Object ( [type] => status [id] => 14047818930362 [created_time] => 2012-03-01T09:36:04+0000 ) 
    [4] => stdClass Object ( [type] => photo [id] => 14047818930362 [created_time] => 2012-02-28T07:03:25+0000 ) 
    [5] => stdClass Object ( [type] => photo [id] => 1404781893036 [created_time] => 2012-02-27T09:15:34+0000 ) 
    [6] => stdClass Object ( [type] => photo [id] => 14047818930362 [created_time] => 2012-02-27T07:32:13+0000 ) 
    [7] => stdClass Object ( [type] => status [id] => 1404781893036 [created_time] => 2012-02-25T09:36:57+0000 )
    [8] => stdClass Object ( [type] => photo [id] => 1404781893036 [created_time] => 2012-02-23T08:46:43+0000 ) 
    [9] => stdClass Object ( [type] => status [id] => 1404781893036 [created_time] => 2012-02-22T21:04:30+0000 ) 
    [10] => stdClass Object ( [type] => status [id] => 1404781893036 [created_time] => 2012-02-21T20:38:27+0000 )
    [11] => stdClass Object ( [type] => photo [id] => 1404781893036 [created_time] => 2012-02-21T07:22:44+0000 ) 
    [12] => stdClass Object ( [type] => status [id] => 14047818930362 [created_time] => 2012-02-20T08:32:46+0000 ) 
    [13] => stdClass Object ( [type] => status [id] => 1404781893036 [created_time] => 2012-02-17T15:00:11+0000 ) )

I'm a PHP newbie and struggling with this one.

解决方案

$count = 0;
foreach ($array as $item) {
  if ($item->type === 'photo') {
    $count++;
  }
}
