我有3个不同的区域,MyArea1,MyArea2,MyArea3。每个都有一系列邮政编码:
$myArea1=array("AB1","AC2","AD1");
$myArea2=array("BC1","BC2","BC3");
$myArea3=array("CD1","CD2","CD3");
我需要检查的邮政编码如下所示" BC2 4YZ"。
以下内容在检查完整匹配时不起作用:
if (in_array($row['postcode'], $myArea1)) { $Area = 'Area 1'; }
else if (in_array($row['postcode'], $myArea2)) { $Area = 'Area 2'; }
else if (in_array($row['postcode'], $myArea3)) { $Area = 'Area 3'; }
else { $Area = 'No Match'; }
我有以下工作:
foreach ($myArea1 as $myArea1pc) {
if (strpos($row['postcode'],$myArea1pc) !== false) {
$Area = 'Area 1';
}
}
但是有没有办法为我的所有数组循环呢?
编辑:有时可能会出现诸如" BC24"在我的阵列中。
答案 0 :(得分:2)
我会尝试使用in_array
。
$input = $row['postcode'];
$areas = array(
'Area 1' => array("AB1","AC2","AD1"),
'Area 2' => array("BC1","BC2","BC3"),
'Area 3' => array("CD1","CD2","CD3"),
);
// Take out the first 3 letter:
$part = substr(trim(str_replace(' ', '', $input)), 0, -3);
$Area = 'No match';
// Find which "area" array contains it
foreach ($areas as $k => $v) {
if (in_array($part, $v)) {
$Area = $k;
break;
}
}
