Replacing array string values which contains multiple special characters in php

Question

I would like to replace array string values which contains multiple special characters to normal one.

Tried Code (array values):

$data['ENV_TEST'] = "rambo";
$data['ENV_DEV'] = "Project Bribara<"${ENV_TEST}"@gmail.com>"

echo str_replace("${ENV_TEST}", $data['ENV_DEV'], $data['ENV_DEV']);

also tried

echo str_replace("\"${ENV_TEST}\"", $data['ENV_DEV'], $data['ENV_DEV']);

Expected:

"Project Bribara<[email protected]>"

Actual:

"Project Bribara<"${ENV_TEST}"@gmail.com>"

How can I get the expected output?

You should on PHP strings sometime. The important part about double quoted strings for your question is that you need to put a backslash before every $ and every " inside your string. Your code will then look like this:

$data['ENV_TEST'] = "rambo";
$data['ENV_DEV'] = "Project Bribara<\"\${ENV_TEST}\"@gmail.com>";

echo str_replace("\${ENV_TEST}", $data['ENV_TEST'], $data['ENV_DEV']);
//also tried
echo "\n\n";
echo str_replace("\"\${ENV_TEST}\"", $data['ENV_TEST'], $data['ENV_DEV']);

If you use single quoted strings you don't need to escape $ (see the manual), and instead of \", you would need to escape single quotes (but there aren't any in your example).

$data['ENV_TEST'] = "rambo";
$data['ENV_DEV'] = 'Project Bribara<"${ENV_TEST}"@gmail.com>';

echo str_replace("\${ENV_TEST}", $data['ENV_TEST'], $data['ENV_DEV']);
//also tried
echo "\n\n";
echo str_replace('"${ENV_TEST}"', $data['ENV_TEST'], $data['ENV_DEV']);

I also fixed a missing semicolon and replaced DEV with TEST in one place.

String concatenation in PHP is done through the . operator. Your code would be:

$data['ENV_DEV'] = "Project Bribara<".$data['ENV_TEST']."@gmail.com>"
