我有以下正则表达式:
public static void main(String[] args) {
int i = 5;
int j = 0;
for (int k = 1; k <= i; k++) {
System.out.println("row count is " + j);
j = increment(j); // IT is important to store it in `j` again, otherwise j will still be 2 after the execution
j += 1;
}
}
private static int increment(int j) {
if (j == 2) {
j += 1;
System.out.println("row count is " + j);
}
return j;
}
如何改善这一点,使其与href标签中的“files”或“resize”字词不匹配:
$regex = '<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*)<\/a>';

是的,解析是更好的方法来做到这一点 - 也许有人觉得这很有帮助:
$i=0;
$code=$_POST['code'];
$img=$_POST['img'];
$name=$_POST['name'];
$short_description=$_POST['short_description'];
$columns = array(
if($code){
array('db' => 'code', 'dt' => $i),
i++;
}else if($img){
array('db' => 'img', 'dt' => $i),
i++;
}else if($name){
array('db' => 'name', 'dt' => $i),
i++;
}else if($short_description){
array('db' => 'short_description', 'dt' => $i),
}
);

您可以使用此正则表达式获取所有href字符串:
<a[^>]*href=[\"\'](.*?)[\"\'][^>]*>(.*?)</a>
