By design. Based on OP example and words; not based on your hypothetical input.
You should start a new thread if you would like me to provide a solution for you, addressing your input.
It is my belief that the original request was to change semicolon delimiters inside double-quoted strings to vertical bar delimiters. But, the given examples did not include a case where more than on delimiter appeared inside double quotes. Therefore, the original request is not as clear as I would like.
I did not ask you to make any changes.
I see no reason to start a new thread when pointing out to the original poster that the code suggested by you, the code suggested by greet_sed, and the code suggested by me (and refined to a better suggestion by RudiC) do three different things if there is more than one semicolon inside double quotes: Your suggestion changes the 1st semicolon, greet_sed's suggestion doesn't change anything, and my and RudiC's suggestion changes every semicolon.
I believe it is entirely up to bartleby to determine if any of this matters in the real input he/she will be processing (instead of the contrived 2-line sample input) and, if it does matter, to choose the suggestion that behaves the way bartleby wants it to behave. But, I believe that bartleby should be made aware in this thread that the three suggestions do not do the same thing and should be warned to determine whether the differences in our solutions matter.

LEARN ABOUT PHP
str_ireplace
STR_IREPLACE(3) 1 STR_IREPLACE(3)
str_ireplace - Case-insensitive version ofstr_replace(3).
SYNOPSIS
mixed str_ireplace (mixed $search, mixed $replace, mixed $subject, [int &$count])
DESCRIPTION
This function returns a string or an array with all occurrences of $search in $subject (ignoring case) replaced with the given $replace
value. If you don't need fancy replacing rules, you should generally use this function instead of preg_replace(3) with the i modifier.
PARAMETERS
If $search and $replace are arrays, then str_ireplace(3) takes a value from each array and uses them to search and replace on $subject. If
$replace has fewer values than $search, then an empty string is used for the rest of replacement values. If $search is an array and
$replace is a string, then this replacement string is used for every value of $search. The converse would not make sense, though.
If $search or $replace are arrays, their elements are processed first to last.
o $search
- The value being searched for, otherwise known as the needle. An array may be used to designate multiple needles.
o $replace
- The replacement value that replaces found $search values. An array may be used to designate multiple replacements.
o $subject
- The string or array being searched and replaced on, otherwise known as the haystack. If $subject is an array, then the search
and replace is performed with every entry of $subject, and the return value is an array as well.
o $count
- If passed, this will be set to the number of replacements performed.
RETURN VALUES
Returns a string or an array of replacements.
EXAMPLES
Example #1
str_ireplace(3) example
<?php
$bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
?>
NOTES
Note
This function is binary-safe.
Caution
Replacement order gotcha
Because str_ireplace(3) replaces left to right, it might replace a previously inserted value when doing multiple replacements.
Example #2 in the str_replace(3) documentation demonstrates how this may affect you in practice.
