我想为每个以"结尾的句子添加span标签。如:我的字符串:
"我怎能说:‘你用亲嘴出卖人子吗?除非我相信背叛。被钉在十字架上的整个信息很简单，就是我没有。"
O/p:
"<span id="s1">I could not have said, ’Betrayest thou the Son of man with a kiss?’ unless I believed in betrayal.</span> <span id="s2">The whole message of the crucifixion was simply that I did not.</span>"
怎么可能用php?
你可以做
<?php
$string="I could not have said, ’Betrayest thou the Son of man with a kiss?’ unless I believed in betrayal. The whole message of the crucifixion was simply that I did not.";
$output=str_replace(". ",'. </span> <span id="s2">',$string);
echo '<span id="s1">'.$output.'</span>';
?>
基于注释编辑
这个版本将确保每个新的替换得到一个新的span id
<?php
$string="I could not have said, ’Betrayest thou the Son of man with a kiss?’ unless I believed in betrayal. The whole message of the crucifixion was simply that I did not. Testing 123. testing again.";
$dots=substr_count($string,". ");
for($i=2;$i<=$dots+2;$i++)
{
$string=preg_replace("/'. /", ".</span> <span id ='"s$i'">" ,$string,1);
}
echo '<span id="s1">'.$string.'</span>';
?>
如果你用"。"。我想修改上面的代码。
$newText = "";
$count = 0;
foreach (explode(". ",$theText) as $part) {
if(ctype_upper($part{0}))
{
$count++;
$newText .= "<span id='"s$count'">$part</span>";
}
}
我希望它应该工作的缩写或其他
试试下面的代码，您将获得span标记的唯一id。
<?php
$str = "I could not have said, 'Betrayest thou the Son of man with a kiss?' unless I believed in betrayal. The whole message of the crucifixion was simply that I did not.";
$exp_str = explode(". ",$str);
$sentence = "<span id='"s1'">";
$n = 2;
foreach($exp_str as $val) {
$sentence .= $val.".</span> <span id='"s$n'">";
$n++;
}
$n = $n-1;
$sentence = substr($sentence,0,strpos($sentence,".</span> <span id='"s$n'">"));
echo $sentence;
?>
我不确定preg_replace是否可以做到这一点(因为唯一的id)。否则，可以像这样手动完成:
$newText = "";
$count = 0;
foreach (explode(".",$theText) as $part) {
$count++;
$newText .= "<span id='"s$count'">$part</span>";
}
但是句子中间的句号呢，比如缩写之类的?你可以用preg_split代替explode来得到更好的结果。例如，只有当句点后面的字符不是字母或其他句点时才进行分割。
preg_split("/'.[^','w]/",$theText);
或者确保下一个字符是空格。
preg_split("/'.'s/",$theText);
