用PHP中的“…”主体缩短字符串?
假设以下是我们的字符串-
$sentence="This is my first PHP program";
我们想要以下输出-
This is my first PHP ... gram
我们用“…”缩短字符串。为此,请使用的概念substring()并通过检查单词数来设置条件-
示例
<!DOCTYPE html>
<html>
<body>
<?php
$sentence="This is my first PHP program";
if (strlen($sentence) >= 13) {
echo substr($sentence, 0, 20). " ... " . substr($sentence, -4);
} else {
echo $sentence;
}
?>
</body>
</html>输出结果
This is my first PHP ... gram
