php字符串转化成数组解决思路

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

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

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

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