Add string at the end position of particular text in a string

Question

I need to append a text at the end position of the search term.

$baseStr = 'www.abc.com/cdf/?x=10';
$searchStr = 'www.abc.com/';
$insertStr = 'xxx/';

I need to insert $insertStr after 'www.abc.com/' in $baseStr. I get only the start position using strpos.

Expected result:

$resultStr = 'www.abc.com/xxx/cdf/?x=10';

Edit: Is it possible to find the end position of the search string and solve this?

start of $baseStr is fixed? I mean "www.abc.com"?

You can just replace $searchStr with $searchStr plus $insertStr

$baseStr = 'www.abc.com/cdf/?x=10';
$searchStr = 'www.abc.com/';
$insertStr = 'xxx/';
$resultStr = str_replace($searchStr, $searchStr.$insertStr, $baseStr);
echo $resultStr;

gives

www.abc.com/xxx/cdf/?x=10

Use preg_replace here:

$baseStr = 'www.abc.com/cdf/?x=10';
$searchStr = 'www.abc.com/';
$insertStr = 'xxx/';

$a = preg_replace('#'.$searchStr.'#', $searchStr.$insertStr, $baseStr);
echo '<pre>';
print_r($a);

//Output: www.abc.com/xxx/cdf/?x=10

Or you can use str_replace:

$baseStr = 'www.abc.com/cdf/?x=10';
$searchStr = 'www.abc.com/';
$insertStr = 'xxx/';

$a = str_replace($searchStr, $searchStr.$insertStr, $baseStr);
echo '<pre>';
print_r($a);

//Output: www.abc.com/xxx/cdf/?x=10

You can do something like this,

echo str_replace($searchStr, $searchStr.$insertStr,$baseStr);

Just replace your string it will search and replace for you.

Demo.
