我找到了opsite的解决方案:"在第二个"-"出现的字符之后剥离字符串中的所有内容?"
$newstr = substr($str, 0, strpos($str, '-', strpos($str, '-')+2));
现在,我需要解决"之前"的第二个"-":
Today is - Friday and tomorrow is - Saturday
未来:
Saturday
如果可能的话,我想用strstr()来做这件事。
我试过类似的东西:
$newstr = substr($str, 0, strstr($str, '-', strstr($str, '-')+2));
没用。
$testString = "Today is - Friday and tomorrow is - Saturday";
$newString = substr(strstr(substr(strstr($testString, "-"),1),"-"),1);
echo $newString;//print Saturday
查找第一个-
之后的子字符串,然后查找其中第一个-
之后的子串。
使用爆炸的替代方法。
$str = "Today is - Friday and tomorrow is - Saturday";
$parts = explode("-", $str, 3);
if (count($parts) == 3){
$res = array_pop($parts);
} else {
// handle the case where there is no second delimiter.
$res = "";
}
echo $res;
