This post if the 3rd of my serie on PHP useful functions. You can find my other posts about <a href=\"https:\/\/bastienmalahieude.fr\/en\/importer-un-fichier-csv-en-tableau-php\/\">Importing a CSV file in PHP<\/a> and <a href=\"https:\/\/bastienmalahieude.fr\/en\/export-array-php-csv-microsoft-excel\/\">Export a PHP array in a CSV File<\/a>.<\/p>\n<p>This function is used to transform a string such as <strong>Jean-MARIE De la rue<\/strong> into <strong>Jean-Marie De La Rue<\/strong><\/p>\n<p>For this, we will create a custom fonction\u00a0<em>uc_first<\/em> that takes the name of the user as a parameter and output a formatted string. This functions takes two parameters, but only the first one is required :<\/p>\n<ul>\n<li><strong>$name<\/strong> : This parameter is the name you wish to transform<\/li>\n<li>$<strong>delimiters<\/strong> : The delimiters you wish to use, they separate words. By default, the function is using the dash &#8220;-&#8221; et the space &#8221; &#8220;<\/li>\n<\/ul>\n<pre> function uc_first($name)\r\n{\r\n\/\/ @TODO Do something here\r\n}<\/pre>\n<p>In a first time, we will make sure that the name passed is not\u00a0<em>null<\/em>. This step is not required, but can help you some troubles.<\/p>\n<pre>if(null === $name) {\r\n    return $name;\r\n}<\/pre>\n<h3>Description of the process<\/h3>\n<p>Then we will follow two distinct steps :<\/p>\n<ul>\n<li>First, cut the string in multiple chunks, using the delimiters set previously. This step will use the function\u00a0<em>preg_split<\/em> and a regular expression.<\/li>\n<li>Then, we will take every chunk and capitalize their first letter.<\/li>\n<\/ul>\n<p>The first step is to create the regexp pattern. <a href=\"https:\/\/regex101.com\/\" target=\"_blank\" rel=\"noopener\">More information on Regular expressions is available here<\/a>.<\/p>\n<pre>$pattern = \"#([$delimiters])#\";<\/pre>\n<p>Then you get an array containing all the elements, according to our regex:<\/p>\n<pre>$chunks = preg_split($pattern, $name,-1, PREG_SPLIT_DELIM_CAPTURE);<\/pre>\n<p>Using the flat PREG_SPLIT_DELIM_CAPTURE, allows use to keep the delimiters inside the\u00a0<em>chunks <\/em>array.<\/p>\n<h3>Capitalize everything !<\/h3>\n<p>To finish, on every element cut, pass the chain into lowercase using\u00a0<em>strtolower<\/em> then capitalize the first letter with\u00a0<em>ucfirst<\/em>.<\/p>\n<pre>foreach ($chunks as &amp;$n) {\r\n    $n = ucfirst(strtolower($n));\r\n}<\/pre>\n<p>We&#8217;re using here the character &amp; within our\u00a0<em>foreach <\/em>loop. It keeps the variable\u00a0<em>$n <\/em>as a reference within the array $chunks. If the variable $n is updated then so is the corresponding line in the\u00a0<em>chunks<\/em> array.<\/p>\n<p>Then, the last step consists into reassembling the array into a string :<\/p>\n<pre>$name = implode('',$chunks);\r\n\r\nreturn $name;<\/pre>\n<h2>FINAL PHP FUNCTION :<\/h2>\n<p>Here is the final version of the function we just created :<\/p>\n<pre>\/**\r\n *\r\n * This function allows you to add a capitalize letter to every letter of a word.\r\n *\r\n * @Exemple : \"Jean-MARIE De la rue\" will become \"Jean-Marie De La Rue\"\r\n *\r\n * @param string|null $name\r\n * @param string $delimiters\r\n *\r\n * @return string|null\r\n *\/\r\nfunction uc_first($name,$delimiters = \" -\")\r\n{\r\n    \/\/ Return null name is not defined\r\n    if(null === $name) {\r\n        return $name;\r\n    }\r\n\r\n    \/\/ Here we use \"-\" and \" \" as separators.
