Remove a certain character from a string in PHP

Method 1: Using str_replace() function

Example 1:

The following source code will remove all the occurrences of hyphens (-) from a phone number string.

<?php
$phone = "123-456-7890";
$phone = str_replace('-', '', $phone);
echo $phone;
?>
Output:
1234567890

Exaple 2:
To remove the occurrences of multiple characters or phrases in a string.

<?php
$string = "Apple, (Mango), 'Banana'";
$newstring = str_replace(array("(", ")", "'"), "", $string);
echo $newstring;
?>
Output:
Apple,Mango,Banana

Method 2: Using preg_replace() function

Method 1:

The preg_replace() function performs a regular expression search and replace, and returns a resulting string.

<?php
$phone = '123-456-7890';
$phone = preg_replace('/-/', '', $phone);
echo $phone;
?>

Output:
1234567890

Example 2:

To remove the occurrences of multiple characters in a string using this method, we include them in our regular expression.

<?php
$string = "Apple, (Mango), 'Banana]'";
$newstring = preg_replace("/[()']/", "", $string);
echo $newstring;
?>

Output:
Apple,Mango,Banana

Method 3: Using str_split() and implode()

The str_split() function splits a string into an array.

<?php
$phone = "123-456-7890";
$phoneArray = str_split($phone);
$phoneArray = array_filter($phoneArray, function ($char) {
return $char !== '-';
});
$phone = implode('', $phoneArray);
echo $phone;
?>

Output:
1234567890
