How to convert array to URL parameters in PHP

How to convert an array into a URL parameter in PHP

1. Use the PHP built-in function "http_build_query()" to convert a string into a URL parameter;

Usage example:

<?php
$data = array(
    &#39;foo&#39; => &#39;bar&#39;,
    &#39;baz&#39; => &#39;boom&#39;,
    &#39;cow&#39; => &#39;milk&#39;,
    &#39;php&#39; => &#39;hypertext processor&#39;
);

echo http_build_query($data) . "\n";
echo http_build_query($data, &#39;&#39;, &#39;&amp;&#39;);

?>

Output result:

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&baz=boom&cow=milk&php=hypertext+processor

2. Use loops to splice the arrays according to the URL parameter rules, and use "=" to splice the array units for keys and values. Just use "&" to splice.

Simple example:

function array_to_url_prarm($array)
{
  $prarms = [];

  foreach ($array as $key => $val) {
    $prarms[] = $key . '=' . str_replace(' ', '+', $val);
  }

  return implode('&', $prarms);
}
