Cara menggunakan javascript array line break

In this article, we are given a multiline string and the task is to replace line breaks with <br> tag.

Example:

Input: `Geeks for Geeks is 
a computer science portal 
where people study computer science`
Output: "Geeks for Geeks is <br> a computer science portal <br> where people study computer science"

To achieve this we have the following methods :

Method 1: Using Regex, in this example, we are creating a paragraph and a button and on clicking the button we are changing (Adding the <br>)the text of the paragraph.

We are using the String.replace() method of regex to replace the new line with <br>. The String.replace() is an inbuilt method in JavaScript that is used to replace a part of the given string with another string or a regular expression. The original string will remain unchanged.

Example 1: This example shows the use of string.replace() method to replace the new line with <br>.

HTML

<p id="para"></p>

<<1 <2=<4<5<1>

<<9>

p1p2

p3p4

p3p6

p7 

p1p9

p7 

p1id2

p7 

p1id5

id6id7id8>

id6=1id8=3

p7 

id6=6

id6id2

p1"para"0

"para"1<9>

Output:

Replace line breaks with br tag

Method 2: Using split() and join(), in this method, we split the string from the delimiter “\n” which returns an array of substrings, and then we join the Array using the join method and pass <br /> so that every joining contains <br />.

Example 2: In this example, we will use the javascript split() and join() method to replace the new line with

Here's a PHP version of print_r which can be tailored to your needs. Shows protected and private properties of objects and detects recursion (for objects only!). Usage:

void u_print_r ( mixed $expression [, array $ignore] )

Use the $ignore parameter to provide an array of property names that shouldn't be followed recursively.

function u_print_r($subject, $ignore = array(), $depth = 1, $refChain = array())
{
    if ($depth > 20) return;
    if (is_object($subject)) {
        foreach ($refChain as $refVal)
            if ($refVal === $subject) {
                echo "*RECURSION*\n";
                return;
            }
        array_push($refChain, $subject);
        echo get_class($subject) . " Object ( \n";
        $subject = (array) $subject;
        foreach ($subject as $key => $val)
            if (is_array($ignore) && !in_array($key, $ignore, 1)) {
                echo str_repeat(" ", $depth * 4) . '[';
                if ($key{0} == "\0") {
                    $keyParts = explode("\0", $key);
                    echo $keyParts[2] . (($keyParts[1] == '*')  ? ':protected' : ':private');
                } else
                    echo $key;
                echo '] => ';
                u_print_r($val, $ignore, $depth + 1, $refChain);
            }
        echo str_repeat(" ", ($depth - 1) * 4) . ")\n";
        array_pop($refChain);
    } elseif (is_array($subject)) {
        echo "Array ( \n";
        foreach ($subject as $key => $val)
            if (is_array($ignore) && !in_array($key, $ignore, 1)) {
                echo str_repeat(" ", $depth * 4) . '[' . $key . '] => ';
                u_print_r($val, $ignore, $depth + 1, $refChain);
            }
        echo str_repeat(" ", ($depth - 1) * 4) . ")\n";
    } else
        echo $subject . "\n";
}

Example:

class test {

    public $var1 = 'a';
    protected $var2 = 'b';
    private $var3 = 'c';
    protected $array = array('x', 'y', 'z');

}

$test = new test();
$test->recursiveRef = $test;
$test->anotherRecursiveRef->recursiveRef = $test;
$test->dont->follow = 'me';
