Php 如何仅从自定义公共函数中获取特定值
功能是:Php 如何仅从自定义公共函数中获取特定值,php,public,Php,Public,功能是: public function getData($symbol='', $stat='') { if (is_array($this->symbol)) { $symbol = implode("+", $this->symbol); //The Yahoo! API will take multiple symbols } if($symbol) $this->_setParam('symbol', $symbol);
public function getData($symbol='', $stat='') {
if (is_array($this->symbol)) {
$symbol = implode("+", $this->symbol); //The Yahoo! API will take multiple symbols
}
if($symbol) $this->_setParam('symbol', $symbol);
if($stat) $this->_setParam('stat', $stat);
$data = $this->_request();
if(!$this->history) {
if ($this->stat === 'all') {
foreach ($data as $item) {
//Add to $return[$symbol] array. Indice 23 is the symbol.
$return[$item[23]] = array(
'name' => strip_tags($item[20]),
'price' => strip_tags($item[0]),
'change' => strip_tags($item[1]),
'volume' => strip_tags($item[2])
//'avg_daily_volume' => strip_tags($item[3]),
//'stock_exchange' => strip_tags($item[4]),
//'market_cap' => strip_tags($item[5]),
//'book_value' => strip_tags($item[6]),
//'ebitda' => strip_tags($item[7]),
//'dividend_per_share' => strip_tags($item[8]),
//'dividend_yield' => strip_tags($item[9]),
//'earnings_per_share' => strip_tags($item[10]),
//'fiftytwo_week_high' => strip_tags($item[11]),
//'fiftytwo_week_low' => strip_tags($item[12]),
//'fiftyday_moving_avg' => strip_tags($item[13]),
//'twohundredday_moving_avg' => strip_tags($item[14]),
//'price_earnings_ratio' => strip_tags($item[15]),
//'price_earnings_growth_ratio' => strip_tags($item[16]),
//'price_sales_ratio' => strip_tags($item[17]),
//'price_book_ratio' => strip_tags($item[18]),
//'short_ratio' => strip_tags($item[19]),
//'name' => strip_tags($item[20])
);

} else {
foreach ($data as $item)
$return[] = array($this->stat => $item);
}
} elseif(is_array($this->history)) {
$return = $data;
}
return $return;
}
index.php上使用的是:
<?php $test3 = ($StockMarketAPI2->getData());
print_r($StockMarketAPI2->getData());
?>
但我唯一需要的是:
阿里巴巴,81,-0.12,gopro,49。。。。等等
所以
我需要的不是某种形式的树
|
||
/\\
就像现在的输出一样。但是只有一行
不是['s]'s('s)'s'数组的。。。。或者其他类似的符号
我该怎么做
是这样的吗
打印($StockMarketAPI2->getData([$item][0]) 试试看:
<?php $test3 = ($StockMarketAPI2->getData());
foreach($test3 as $t){
echo "New subarray!";
echo $t[name];
echo $t[price];
echo $t[change];
echo $t[volume];
}
?>
未测试谢谢Ron!!!!你帮我找到了解决办法。下面是代码:
<?php $test3 = ($StockMarketAPI2->getData());
foreach($test3 as $t){
echo "New subarray!";
echo $t[name];
echo $t[price];
echo $t[change];
echo $t[volume];
}
?>
