php - how can i use preg_match and get value?

Question

i am using this code and its getting No ending delimiter '/' found

    $dp = explode("/",$desp);

    $dp1 = $dp[0];
    $dp2 = $dp[1];
}

in $desp i have value like abc/xyz then it should be like

$dp1 = abc
$dp2 = xyz

so what is the right code thnx.

Answer 1

您应该改用 strpos 。无论如何，您收到该错误的原因是该模式没有分隔符。

带分隔符的模式示例：

if (preg_match("~/~", $desp))

但是，您应该做什么：

if (strpos($desp, '/') !== false)

Answer 2

那样做

$str = "abc/xyz";
$pattern = '/\//';
if(preg_match($pattern, $str))
    echo "foo";

你必须用反斜杠转义你的斜杠才能让它工作
