Php echo entire array how to#
Now, let’s see the PHP code to print an array using echo statements.Įxample 3.1: This example will show you how to use an echo statement to print all the values of an array one by one. While in terms of arrays, echo is not the only solution but it is still helpful in many cases.įor example, echo helps a lot when we want to print a single value of an array. In PHP, whenever we want to print something, we use echo statements. The echo statement is useful in some cases, now let’s see that in the next method. But there is an echo statement that we use mostly to print a single array element. We use these variables inside the loop to print the keys and values of an associative array. You can give any name to $key and $value variables, these variables will hold the value of named indexes and their values.In that Foreach loop, I used the array name ($students) with $key and $value variables. And the indentation you’re seeing is optional, you can write the associative array on just 1 line. The length of the above-indexed array is 4 which starts from 0. 5, in the above code, I used the count() function to get the length of an array in numbers and stored it in a variable ( $arrlength). Now, let’s print all the values of an array using for loop. In this example, I will create an indexed array with the name $students. Also, you can print each array element on a new line or inside the HTML table. By using a loop, you can print all the values of an array at the same time in different ways.įor example, you can use this PHP method to print an array line by line. Using for loop is the most suitable way to print PHP array content. Tip: Don’t know how to run PHP on your PC? See this guide on how to run PHP code. Not just simple indexed arrays, examples to print associative arrays, and multi-dimensional arrays are also included in this guide. In PHP, We use the Following 6 Methods to Print Arrays :Īlso, you will learn each method with an example.
And we’re going to discuss all that in this tutorial. And in PHP, we have various methods to print arrays. Whether it’s an indexed array, associative array, or multidimensional array, you’ll see each of them in this all-in-one guide.Īrrays are very useful when we want to store multiple values in one variable.

I am trying to write a program that sends out a newsletter but I am lost at returning an array of emails.
This is the php of my page (without the mysql data):Ĭonfused about the issue, first time using functions. I tested my code on another page and it works flawlessly, perhaps this error is just generated before it actually exists i dunno.įatal error: Can't use function return value in write context in /home/a8152576/public_html/SecretSanta.html on line 41
I tried to put an invalid ID, and already here the script should have died/exited before executing the parts of the code that doesn't work. $result = mysql_query("SELECT * FROM profiles WHERE id=('$getid') LIMIT 1") $result2 = mysql_query("SELECT * FROM profiles_friends WHERE user=('$getid') AND target=('$loginid') LIMIT 1") Īlright, this is one thing that bothers me, the other is: $result2 = mysql_query("SELECT * FROM profiles_groups WHERE id=('$memgroup') LIMIT 1") Īlright, so the error: Fatal error: Can't use function return value in write context in C:\xampp\htdocs\prog\profile.php on line 45Ĥ2. Įxit("You may not view this profile because of the privacy settings.") Įxit("This account is suspended and cannot be viewed.") Since the last value taken into account is bell then I get two items of the bell brand from my bdd but no arai. $temp = $this->bruteForce($string, FALSE, 0) įunction bruteForce($string, $state, $trys) However, I can't seem to pass the array to librarySolve. I'm trying to return to array of letters that bruteForce finally decides upon. Would appreciate help getting this to work! I haven't coded PHP in like 4 years and I am struggling to return the entire array back to my caling script. Then I could call my getPhotoFilesArray back to my callings cript, and use that array for whatever. It seems to me that I need to encapsulate my code inside a function? Now I would like to move that code to an included file so multiple scripts can access it and always be working with the same array. Then in my HTML, I iterate through this array to display all of the photos for my gallery. So I had a block of code inside my photo-gallery.php script that took the path to my photos directory, and went to that directory, and then read all of the photo filenames into an array.
