我的变量$content包含我的文本.我想从$content创建一个摘录并显示第一个句子,如果句子短于15个字符,我想显示第二个句子.
我已经尝试从文件中删除前50个字符,它可以工作：
<?PHP echo substr($content,50); ?>
但我对结果不满意(我不希望任何词语被削减).
是否有PHP函数获取整个单词/句子,而不仅仅是substr？
非常感谢！
我想通了,但它很简单：
<?PHP
$content = "My name is Luka. I live on the second floor. I live upstairs from you. Yes I think you've seen me before. ";
$dot = ".";
$position = stripos ($content,$dot); //find first dot position
if($position) { //if there's a dot in our soruce text do
$offset = $position + 1; //prepare offset
$position2 = stripos ($content,$dot,$offset); //find second dot using offset
$first_two = substr($content,$position2); //put two first sentences under $first_two
echo $first_two . '.'; //add a dot
}
else { //if there are no dots
//do nothing
}
?>
