SPF/DKIM/DMARC Tools

SPF/DKIM/DMARC deployment tools fall into 2 categories: generators (creators/builders) to generate records and checkers (validators/testers) to look up the DNS.

SPF Tools

To create/generate an SPF record, there is the SPF record generator, or SPF record creator/builder, which takes these mechanisms and qualifiers: mx, a, ip4, ip6, include, and all, and returns an SPF record.

To check an SPF record, there is the SPF record checker, or SPF record validator/tester, which checks if an SPF record is published on your domain, and if its syntax is correct.

DKIM Tools

To create/generate a DKIM record, there is the DKIM record generator, or DKIM record creator/builder, which takes a domain and a selector, and returns a DKIM record.

To check a DKIM record, there is the DKIM record checker, or DKIM record validator/tester, which checks if a DKIM record is published on your domain, and if its syntax is correct.

DMARC Tools

To create/generate a DMARC record, there is the DMARC record generator, or DMARC record creator/builder, which takes these tags: p, rua, ruf, sp, adkim, and aspf, and returns a DMARC record.

To check a DMARC record, there is the DMARC record checker, or DMARC record validator/tester, which checks if a DMARC record is published on your domain, and if its syntax is correct.

Associative arrays – How to loop over Associative arrays

Associative arrays

  • Associative arrays in PHP are arrays that use named keys instead of numeric indexes.
  • This – makes them more expressive and useful when dealing with key-value pairs.
  • Associative arrays can be defined using the array() function or the short array syntax [].

// How to create

$person1 = array("first_name" => "John", "last_name" => "Doe");
$person2 = ["first_name" => "Jane", "last_name" => "Smith"];

// Accessing Values

echo $person1["first_name"];

//Looping Through an Associative Array

foreach ($person1 as $key => $value) {
    echo "$key : $value<br />";
}

Indexed Arrays. How to loop over Indexed Arrays.

// M7C1-LV

Indexed Arrays //24:10-indexed array

You can create an indexed array using the array() function or the short array syntax [].

How to create

$fruits1=array("apple","banana","cherry");
$fruits2=["apple","banana","cherry"];
  • Simple echo will not show the array result without []
  • print_r is use to get array result
print_r($fruits1);
print_r($fruits2);

// Accessing Values of Indexed Array

echo $fruits1[2];
print_r($fruits2[1]);

How to loop over Indexed Arrays // 28:30

// For Loop through an Indexed Array

for ($i=0; $i<count($fruits1); $i++){
echo $fruits1[$i]."\n";
}

// foreach Loop through an Indexed Array

$app=['Android','IOS','Windows','Linux'];
foreach($app as $item){
echo $item."\n";
