到网上找的资料基本都是这个函数

function ext_json_decode($str, $mode=false){

if(preg_match('/\w:/', $str)){

$str = preg_replace('/(\w+):/is', '"$1":', $str);

}

return json_decode($str, $mode);

}

这代码从逻辑上本身就是错误的，比如value里面有个:，解析自然出错，下面是修正过后的

function ext_json_decode($str, $mode=false){

$str = trim( $str );

$str = ltrim( $str, '(' );

$str = rtrim( $str, ')' );

$a = preg_split('#(?

for( $i=0; $i < count( $a ); $i+=2 ){

$s = $a[$i];

$s = preg_replace('#([^\s\[\]\{\}\:\,]+):#', '"\1":', $s );

$a[$i] = $s;

}

//var_dump($a);

$str = implode( '"', $a );

return json_decode($str, $mode);

}
