How to str_replace
</div>
</li>
</ul>
to
</div>
</li>
</ul>
aaa
All the tags in a new line.
I tried
$str = str_replace('</div>\n\r</li>\n\r</ul>', '</div>\n\r</li>\n\r</ul>\n\raaa', $str);
UPDATE CODE:
$str =<<<EOT
</div>
</li>
</ul>
EOT;
$str = str_replace("</div>\n\r</li>\n\r</ul>", "</div>\n\r</li>\n\r</ul>\n\raaa", $str);
echo $str;
\\n
in single quotes is a literal \\
and a literal n
, rather than a \\n
, to get the line breaks you need to use double quotes:
$str = str_replace("</div>\r\n</li>\r\n</ul>", "</div>\r\n</li>\r\n</ul>\r\naaa", $str);
Also, you should be replacing \\r\\n
not \\n\\r
as Windows line breaks are a carriage return \\r
followed by a line break \\n
.
When you use single quotes the \\r\\n
will be treated as string.
Use double quotes instead:
$str = str_replace("</div>\n\r</li>\n\r</ul>", "</div>\n\r</li>\n\r</ul>\n\raaa", $str);
EDIT
Can't you just do:
$str = str_replace('</ul>', "</ul>\n\raaa", $str);
If that isn't suited it's better to resort to rexeg.
First of all: Don't you just want this?
$str = $str . "\n\raaa";
Second, (see Mark Elliot's answer about single versus double quotes)
为什么不串连音?
$str .= "\r\naaa";
