I would like to add span tag for every sentence which ended with "." like: my 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."

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>"

how it possible with php?

</div>

Answer 1

You could do

<?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>';
?>

Edit Based on Comments

This version will make sure every new replacement gets a new 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>';
?>
