how to make a function that sum the array values and make the first value Capital using php-CodePudding

I have problem making answering this question

 <?php

$chars = ["A", 1, 2, "h", "m", "E", "D"];

//Needed Output is: Ahmed

I tried to make that

    foreach ($chars as $char) {
      if (gettype($char) == "string") {
        echo strtolower($char);
      }
    }

The Output is:

ahmed

but I don't how to make the first letter Capital, Is there any function can do that with arrays?

CodePudding user response：

Short answer there is ucfirst , but it only works on string not arrays

So we need to prepare a little bit. You can use implode to convert the array and glue it with empty seperator.

ucfirst with convert only the first letter to Capital letter, so we need to make shure that other letters small letter we can use strtolower to do that

And finaly I prefer using array_filter for that foreach in you code

function testChar($char) {
    return gettype($char) === "string";
}

$chars = ["A", 1, 2, "h", "m", "E", "D"];
$result = array_filter($chars, "testChar");
$stringResult = implode("", $result);
$toLowerstringResult = strtolower($stringResult);
$ucfirstResult = ucfirst($toLowerstringResult);
echo $ucfirstResult;
