如何用php替换url

Question

如何用php替换url为什么这段代码不能工作。请帮帮忙

$mylogo = 'http://example.com/images/logo.png';
 $inputmylogo = 'http://example.com/image.png';
 $file = 'setting.php';
    $content = file_get_contents($file);
    var_dump(preg_replace('/'.$mylogo.'/', $inputmylogo, $content));

你想在这里使用str_replace：

$mylogo = 'http://example.com/images/logo.png';
$inputmylogo = 'http://example.com/image.png';
$file = 'setting.php';
$content = file_get_contents($file);
var_dump(str_replace('/'.$mylogo.'/', $inputmylogo, $content));
