Question

With the following string:

$string='some text <photo id="id#" /> some text';

Make a substr that if the end of its string is a part of

<photo id="id#" />

then apply an extra chunk to complete

"<photo id="id#" />"

Example:

substr($string,0,15);

result is:

some text <phot

If this happens I need to end up with:

some text <photo id="id#" />

He, can’t find the way of doing this. by the way id# is a random numeric value whose length won’t exceed 3 chars. If regex is necessary to come up with a function.

See this:-

output:-

<?php

$str= 'some text <photo id="#xx"/> some test';
$parts = preg_split('~(</?[\w][^>]*>)~', $str, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
echo '<pre>';
print_r($parts);
echo htmlentities($parts[1]);


$str_new= 'some text <photo id="#xx"></photo> some test';
$parts_new = preg_split('~(</?[\w][^>]*>)~', $str_new, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
echo '<pre>';
print_r($parts_new);
echo htmlentities($parts_new[1]);
echo htmlentities($parts_new[2]);

?>
