Question

如何将此字符串拆分为自定义格式？

输入字符串：

foreach($amount[0] as $aountlist){ 
    //$aountlist.= "'".$aountlist->HPIAmount.',';
    print_r($aountlist->HPIAmount);

    $defineamount = [$aountlist->HPIAmount];
}

预期产出：

event_id, horse_id, place, money

当前代码：

ENTRY (TABLE NAME)
COLUMNS IN TABLE ENTRY:
Event_id,
Horse_id
Place

PRIZE (TABLE NAME)
COLUMNS IN TABLE PRIZE:
Event_id,
Place,
Money

如何更改代码以获得预期的输出？

Answer 1

尝试 -

$string = '14157.72,39140.94,36383.66,38508.00,8424.00';
$temp = array();
$str = explode(',', $string);
foreach($str as $val){
   $temp[] = "[".$val."]";
}
echo implode(',', $temp);

Answer 2

这应该适合你：

首先用逗号表示explode()字符串，然后再次implode()。

$str = "14157.72,39140.94,36383.66,38508.00,8424.00";
echo "['" . implode("'],['", explode(",", $str)) . "']";

输出：

['14157.72'],['39140.94'],['36383.66'],['38508.00'],['8424.00']

Answer 3

$string = "14157.72,39140.94,36383.66,38508.00,8424.00"
$result = preg_replace('/([\d\.]+)/m', '[\'$1\']', $string );

echo $result;

输出：

['14157.72'],['39140.94'],['36383.66'],['38508.00'],['8424.00']
