For this, use preg_replace() in PHP. You need to also use Regular Expressions. Let’s say the following is our input −
FirstName|John |LastName|Smith|SalaryProvided|2000|5000
The expected output is as follows wherein we have replaced a specific character “|” with a whitespace. This character was placed between two numbers 2000 and 5000 −
FirstName|John |LastName|Smith|SalaryProvided|2000 5000
Example
The PHP code is as follows
<!DOCTYPE html>
<html>
<body>
<?php
$SQLDatabaseResult = "FirstName|John |LastName|Smith|SalaryProvided|2000|5000";
$output = preg_replace("/(\d{4})\|(?=\d{4})/", "$1 ", $SQLDatabaseResult);
echo "The result is=","<br>";
echo $output;
?>
</body>
</html>Output
This will produce the following output
The result is= FirstName|John |LastName|Smith|SalaryProvided|2000 5000
