In PHP, you can use the built-in str_replace() function to replace a symbol in a text string. The syntax for using this function is as follows:
1
|
str_replace($search, $replace, $string);
|
- $search: This parameter specifies the symbol or string you want to find within the text string.
- $replace: This parameter determines what you want to replace the found symbols/strings with.
- $string: This parameter is the original text string in which you want to perform the replacement.
The str_replace() function will return a modified string with the specified symbols/strings replaced.
Here is an example usage:
1 2 3 4 |
$text = "Hello, World!"; $updatedText = str_replace(",", "-", $text); echo $updatedText; |
In this example, the comma symbol (",") in the original string is replaced with a hyphen symbol ("-"). The output of the above code would be:
1
|
Hello- World!
|
You can replace any symbol or string within a text by specifying the appropriate values for the three parameters in the str_replace() function.

How can I substitute a character in a string using PHP?
To substitute a character in a string using PHP, you can use the str_replace() function.
The str_replace() function takes three parameters:
- The character (or substring) you want to replace.
- The character (or substring) you want to replace it with.
- The original string.
Here's an example:
1 2 3 4 |
$string = "Hello, world!"; $newString = str_replace("o", "x", $string); echo $newString; // Outputs "Hellx, wxrld!" |
In this example, we replace the character "o" with "x" in the original string "Hello, world!" using the str_replace() function. The resulting string is then stored in the $newString variable and printed out.
Note that str_replace() is case-sensitive by default. If you want a case-insensitive replacement, you can use the str_ireplace() function instead.
