我有一个看起来像这样的数组($ myArray)
Array ( [0] => Array ( [0] => Array ( [ID] => 322 [Number] => 1 [Date] => 3117-01-41 [example] => Hello )
[1] => Array ( [ID] => 123 [Number] => 49 [Date] => 1717-05-21 [example] => Hi )
[2] => Array ( [ID] => 007A [Number] => 42 [Date] => 2005-11-24 [example] => Some Text )
[3] => Array ( [ID] => 999AAA [Number] => 492 [Date] => 3117-01-21 [example] => Text Test Text )))
在我的页面中,我使用的函数返回内容($ content),并且该内容显示在Web浏览器上。没有回显或打印只返回不断被追加到的内容变量。
我真的想循环遍历我的数组并将某个字段的值打印到屏幕上,例如
while(//not sure what goes here){
$content .= '<p>'.$someVariable["Number"].'</p>';
$content .= '<p>'.$someVariable["example"].'</p>';
$content .= '<p>'.$someVariable["date"].'</p>';
}
我不确定while循环是否是实现所需结果的最佳方法。另外使用fetch_array不是我可以使用的选项,因为它会破坏以前的代码。

<?php
$yourArray = array (
array (
'ID' => 322,
'Number' => 1,
'Date' => '3117-01-41',
'example' => 'Hello'
),
array (
'ID' => 123,
'Number' => 49,
'Date' => '1717-05-21',
'example' => 'Hi'
),
array (
'ID' => '007A',
'Number' => 42,
'Date' => '2005-11-24',
'example' => 'Some Text'
),
array (
'ID' => '999AAA',
'Number' => 492,
'Date' => '3117-01-21',
'example' => 'Text Test Text'
)
);
?>
打印整个数组:
<?php print_r($yourArray); ?>
打印某些级别的数组:
<?php print_r($yourArray[2]); ?>
打印数组的某些元素:
print_r($yourArray[2]['Date']);
逐级打印数组:
<?php
for($index=0; $index < count($yourArray); $index++){
echo $yourArray[$index]['ID'].'<br>';
echo $yourArray[$index]['Number'].'<br>';
echo $yourArray[$index]['Date'].'<br>';
echo $yourArray[$index]['example'].'<br>';
};
?>

这有帮助吗?
import os
import lxml.etree as et
dir = "C:\\Path\\To\\XML\\Files"
# LOOP THROUGH FILES IN DIRECTORY
for f in os.listdir(dir):
if f.endswith('.xml'):
# PARSE XML
doc = et.parse(os.path.join(dir, f))
for i in range(1,len(doc.xpath('//master'))+1):
# PARSE XSLT (same xslstr as above -no need to loop it)
xsl = et.fromstring(xslstr.format(i))
# TRANFORM INPUT TO OUTPUT
transform = et.XSLT(xsl)
result = transform(doc)
# SAVE OUTPUT
outfile = doc.xpath('//master[{}]/@name'.format(i))[0] + '.xml'
with open(os.path.join(dir, outfile), 'wb') as f:
f.write(result)

看来你正在寻求这个:
$yourArray = array (
array (
'ID' => 322,
'Number' => 1,
'Date' => '3117-01-41',
'example' => 'Hello'
),
array (
'ID' => 123,
'Number' => 49,
'Date' => '1717-05-21',
'example' => 'Hi'
),
array (
'ID' => '007A',
'Number' => 42,
'Date' => '2005-11-24',
'example' => 'Some Text'
),
array (
'ID' => '999AAA',
'Number' => 492,
'Date' => '3117-01-21',
'example' => 'Text Test Text'
)
);
$content = '';
foreach($yourArray as $key => $value):
$content .= '<p>'.$value["Number"].'</p>';
$content .= '<p>'.$value["example"].'</p>';
$content .= '<p>'.$value["Date"].'</p>';
endforeach;
print $content;
