Combine substr_replace with str_replace in php

Question

What I am trying to do is to replace a specific string with another only if found in a certain position.

php:

$substr = substr_replace($string, $replacement, $stringstart);
$str = str_replace($quoted, $replacement, $str);

I plan to replace $string with $replacement in the string $str but only after $stringstart characters.

I also have $stringend. If I could also use that(because I know exactly the length of $replacement), it would be great. This is optional though

Interesting. Any question/problem where we can help you? How to Ask — idmean

Would be a lot more helpful if you could provide sample input and output. — Mark Miller

I did read that. What is that you could not understand from my question? I am just starting with PHP and I have used these functions alone but never together. — Marius S

I think this is what you are looking for:

$strToSearch="There is no need searching here. The search need to start here";
echo str_replace("need to start","started",substr($strToSearch, 32, strlen($strToSearch)));

This will produce the result:

"The search started here"

so sorry. I forgot to mention. My $str is an array. I have it printed twice : $str[0] and $str[1]

That makes your question more complex. I dont understand how it fits into the question above. can you correct the Original question?

I have made the explode function after your function. it still does not work as intended. It is deleting EVERYTHING before, also including the $strtosearch.

I want to have $strtosearch wrapped into "div class="example">$strtosearch</div> . This is why I am making the replacement.

You have an $arr which you want to search for a particular string in it or you have a string and want to search your string? I am confused at what your need is
