如何 trim php 中特定字符后的字符串

Question

我是 PHP 的新人，我在变量中保存了一些文本。我正在尝试检索第一个“/”字符后跟的文本。这是我尝试过的。

$var="xxxxx/ttt/tttt/tttt.txt";
echo $str . "<br />";
echo trim($str,"/");

输出必须是ttt/tttt/tttt.txt。如果我能得到一些帮助，我将不胜感激。谢谢。

Answer 1

你可以试试explode函数

$var="xxxxx/ttt/tttt/tttt.txt";

$split = explode('/', $var,2); // it will expload by first occurance of / (delimeter)

//$split[0] will contain "xxxxx"

echo  $split[1]; // output = ttt/tttt/tttt.txt

Answer 2

根据重复，这是你的答案：

$data = "xxxxx/ttt/tttt/tttt.txt";

$whatIWant = substr($data, strpos($data, "/") + 1);

echo $whatIWant;
