Method 1: Using str_replace() Method: The str_replace() method is used to remove all the special character from the given string str by replacing these character with the white space (” “).
Syntax:
str_replace( $searchVal, $replaceVal, $subjectVal, $count )
Example:
<?php
// PHP program to Remove
// Special Character From String
// Function to remove the spacial
function RemoveSpecialChar($str) {
// Using str_replace() function
// to replace the word
$res = str_replace( array( '\'', '"',
',' , ';', '<', '>' ), ' ', $str);
// Returning the result
return $res;
}
// Given string
$str = "Example,to remove<the>Special'Char;";
// Function calling
$str1 = RemoveSpecialChar($str);
// Printing the result
echo $str1;
?>
Method 2: Using str_ireplace() Method: The str_ireplace() method is used to remove all the special character from the given string str by replacing these character with the white space (” “). The difference between str_replace and str_ireplace is that str_ireplace is a case-insensitive.
Syntax:
str_ireplace( $searchVal, $replaceVal, $subjectVal, $count )
Example:
preg_replace( $pattern, $replacement, $subject, $limit, $count ) <?php // PHP program to Remove // Special Character From String // Function to remove the spacial function RemoveSpecialChar($str){ // Using str_ireplace() function // to replace the word $res = str_ireplace( array( '\'', '"', ',' , ';', '<', '>' ), ' ', $str); // returning the result return $res; } // Given string $str = "Example,to remove<the>Special'Char;"; // Function calling $str1 = RemoveSpecialChar($str); // Printing the result echo $str1; ?>
Syntax:
str_replace( $searchVal, $replaceVal, $subjectVal, $count )
Method 3: Using preg_replace() Method: The preg_replace() method is used to perform a regular expression for search and replace the content.
Syntax:
preg_replace( $pattern, $replacement, $subject, $limit, $count )
Example:
<?php
// PHP program to Remove
// Special Character From String
// Function to remove the spacial
function RemoveSpecialChar($str){
// Using preg_replace() function
// to replace the word
$res = preg_replace('/[^a-zA-Z0-9_ -]/s',' ',$str);
// Returning the result
return $res;
}
// Given string
$str = "Example,to remove<the>Special'Char;";
// Function calling
$str1 = RemoveSpecialChar($str);
// Printing the result
echo $str1;
?>
