我正在使用外部.csv文件来推断php中的一些值并进行计算。我的.csv的结构方式如下（这是一个非常简单的例子，我的csv通常有50/60行，每个人都有不同的名字）：
销售额，10,24,56年收入，14,71,105
我想使用php指令只选择名为“Revenues”的行或仅选择名为“Sales”的行。到目前为止，我已经使用了“for”循环，但这仅基于i ++变量。
$csv = str_getcsv(file_get_contents('csv/sample.csv'));
for ($i = 12, $k=$i+11; $i < $k; $i++) {
echo '<td>';
echo number_format($csv[$i],0,'.',',');
echo '</td>';
}
echo '</tr>';
如果“销售”和“收入”的位置不同，我就无法调用正确的值。
更新：
这是print_r（$ csv）

首先使用preg_grep＆amp; file与str_getcsv一起解决您的问题。
首先$file = file('csv/sample.csv');
然后$revenues = preg_grep ('/^Revenues/i', $file);
然后
for ($revenues as $revenue)
{
$revenue = str_getcsv($revenue);
echo $revenue[0] . $revenue[1] . $revenue[2] . $revenue[3];//Revenue key 0,1,2,3
}
然后$sales = preg_grep ('/^Sales/i', $file);
然后
for ($sales as $sale)
{
$sale = str_getcsv($sale);
echo $sale[0] . $sale[1] . $sale[2] . $sale[3];//Sale key 0,1,2,3
}

您可以将csv读入命名的键数组，然后按名称引用相关的行条目。
$csv = array();
$file = new SplFileObject( "csv/sample.csv" );
$file->setFlags( SplFileObject::READ_CSV );
foreach( $file as $index => $row ) {
$csv[ strtolower( $row[0] )]=array_splice( $row, 1, count( $row ) );
}
echo '<pre>',print_r($csv['sales'],true),'</pre>';

试试这个
.search-icon {
font-size: 1.875em;
color: #1CB6B5;
position: absolute;
right: 0px;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
.search-icon-open {
z-index: 1000;
color: #FFF;
right: 400px;
}
如果您希望获得所有数据：
$sales = [];
$revenues = [];
foreach($csv as $key => $val)
{
$sales[] = $val['Sales'];
$revenues[] $val['Revenue'];
}
print_r($sales);
print_r($revenues);
