php - 有没有办法在您的聊天框系统中使用 PHP 来制作笑脸？

Question

我正在尝试分析文本，然后当我看到“:)”时，我会将其替换为图像的路径，有没有办法做到这一点？

提前致谢..

$text = "This would be fun :)"

wanted result = "This would be fun image 路径在这里"

所以我会看到图像的路径显示笑脸而不是“:)”

Answer 1

$text = "This would be fun :)"
$newtext = str_replace(":)", "<img src='images/smiley.png'>", $text);

对于多个替换，请在下面的 php.net 中找到示例

$vowels = array("a", "e", "i", "o", "u", "A", "E", "I", "O", "U");
$onlyconsonants = str_replace($vowels, "", "Hello World of PHP");
// Provides Result: Hll Wrld f PHP
