<?php function imploadValue($types){ $strTypes = implode(",", $types); return $strTypes; } function explodeValue($types){ $strTypes = explode(",", $types); return $strTypes; } function random_code(){ return rand(1111, 9999); } function remove_special_char($text) { $t = $text; $specChars = array( ' ' => '-', '!' => '', '"' => '', '#' => '', '$' => '', '%' => '', '&' => '', '\'' => '', '(' => '', ')' => '', '*' => '', '+' => '', ',' => '', '₹' => '', '.' => '', '/-' => '', ':' => '', ';' => '', '<' => '', '=' => '', '>' => '', '?' => '', '@' => '', '[' => '', '\\' => '', ']' => '', '^' => '', '_' => '', '`' => '', '{' => '', '|' => '', '}' => '', '~' => '', '-----' => '-', '----' => '-', '---' => '-', '/' => '', '--' => '-', '/_' => '-', ); foreach ($specChars as $k => $v) { $t = str_replace($k, $v, $t); } return $t; } |
Add File Path In composer.json File
In this step, we will add helper file path in composer.json file. Go to root directory and open composer.json file and put the following code into the file:
composer.json
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
"autoload": { "classmap": [ ... ], "psr-4": { "App\\": "app/" }, "files": [ "app/helpers.php" ] }, |
Now, go to command prompt and type the given command:
|
1 |
composer dump-autoload |
Now you can use your custom helper functions by calling this functions remove_special_char(), random_code() etc.
Now, I’ll show you how to use custom helper function in your laravel project:
Example 1
|
1 2 |
$code = random_code(); print_r($code); |
Example 2
|
1 2 3 4 5 6 7 |
$str = "remove & special #character *in string@$ example." $remove = remove_special_char($str); print_r($remove); //output remove special character in string example |
