php字符串转化成数组解决思路

分享到：

------解决方案--------------------

$s = 'sex-1-area-2-pagesize-18-pageindex-1';
foreach(array_chunk(explode('-', $s), 2) as $v) {
  $r[$v[0]] = $v[1];
}
print_r($r);

Array
(
[sex] => 1
[area] => 2
[pagesize] => 18
[pageindex] => 1
)

------解决方案--------------------
也可以用正则

$s = 'sex-1-area-2-pagesize-18-pageindex-1';
preg_match_all('/(\w+)\-(\w+)/', $s, $r);
$r = array_combine($r[1], $r[2]);
print_r($r);

Array
(
[sex] => 1
[area] => 2
[pagesize] => 18
[pageindex] => 1
)

------解决方案--------------------

$test = "sex-1-area-2-pagesize-18-pageindex-1";
	$preg = "/(?<=\d)-(?=[a-z])/";
	$res = preg_split($preg,$test);
	
	foreach($res as $tmp){
		list($key,$value) = explode("-",$tmp);
		echo $key."=>".$value;
	}

------解决方案--------------------

$str = 'sex-1-area-2-pagesize-18-pageindex-1';
$str = explode('-', $str);
for($i=0,$max=count($str);$i<$max;$i++) {
	$result[$str[$i]] = $str[++$i];
}
print_r($result);
