我从xml中获取数据,其中有100个元素,我的代码:
foreach($sections->children() as $question){
$xml_data .= 'Section Name: '.$question->section_name.'<br/>';
$xml_data .= 'Question No.: '.$question->qno.'<br/>';
if($question->answer == null || $question->answer == ''){
$question->answer = 'Not attempted';
$xml_data .= 'Answer: '.$question->answer.'<br/>';
} else {
$xml_data .= 'Answer: '.$question->answer.'<br/>';
}
$xml_data .= 'Time: '.$question->time.'<br/>';
if($question->seen == '1'){
$xml_data .= 'Seen<br/>';
} else {
$xml_data .= 'Not Seen<br/>';
}
if($question->flag == '1'){
$xml_data .= 'Flaged<br/>';
} else {
$xml_data .= 'Not Flaged<br/>';
}
}
从上面我得到了100个问题,但我只能从上面显示25个,我该怎么做?
答案 0 :(得分:1)
$count = 1;
foreach($sections->children() as $question){
...
...
if($count++ == 25){
break;
}
}

这样做:
$t = 1; $rate=array(1 , 2 ,3 ,4 ,5 ); print_r($rate); foreach($rate as $rt){ echo $rt; if($rt==3){ exit;} $t++; }
