不确定您是使用heredoc还是双引号包装字符串,但以下是一种不太贪婪的方法:
$str4 = 'address="St Marks Church",notes="The North East\'s premier..."'
preg_match_all('~(address|notes)="([^"]*)"~i',$str4,$matches)
print_r($matches)
输出
Array
(
[0] => Array
(
[0] => address="St Marks Church"
[1] => notes="The North East's premier..."
)
[1] => Array
(
[0] => address
[1] => notes
)
[2] => Array
(
[0] => St Marks Church
[1] => The North East's premier...
)
)
使用 preg_split 的另一种方法:
//split the string at the comma
//assumes no commas in text
$parts = preg_split('!,!', $string);
foreach($parts as $key=>$value){
//split the values at the = sign
$parts[$key]=preg_split('!=!',$value);
foreach($parts[$key] as $k2=>$v2){
//trim the quotes out and remove the slashes
$parts[$key][$k2]=stripslashes(trim($v2,"'"));
}
}
输出看起来像:
Array
(
[0] => Array
(
[0] => address
[1] => St Marks Church
)
[1] => Array
(
[0] => notes
[1] => The North East's premier...
)
)
超级缓慢的老派方法:
$len = strlen($string);
$key = "";
$value = "";
$store = array();
$pos = 0;
$mode = 'key';
while($pos < $len){
switch($string[$pos]){
case $string[$pos]==='=':
$mode = 'value';
break;
case $string[$pos]===",":
$store[$key]=trim($value,"'");
$key=$value='';
$mode = 'key';
break;
default:
$$mode .= $string[$pos];
}
$pos++;
}
$store[$key]=trim($value,"'");
