Output echo print everything from a PHP Array

Question

Is it possible to echo or print the entire contents of an array without specifying which part of the array   The scenario  I am trying to echo everything from   while  row   mysql fetch array  result    echo  row  id        Without specifying  id  and instead outputting the complete contents of the array

If you want to format the output on your own, simply add another loop (foreach) to iterate through the contents of the current row:

while ($row = mysql_fetch_array($result)) {
    foreach ($row as $columnName => $columnData) {
        echo 'Column name: ' . $columnName . ' Column data: ' . $columnData . '<br />';
    }
}

Or if you don't care about the formatting, use the print_r function recommended in the previous answers.

while ($row = mysql_fetch_array($result)) {
    echo '<pre>';
    print_r ($row);
    echo '</pre>';
}

print_r() prints only the keys and values of the array, opposed to var_dump() whichs also prints the types of the data in the array, i.e. String, int, double, and so on. If you do care about the data types - use var_dump() over print_r().

I think you are looking for print r which will print out the array as text   You can t control the formatting though  it s more for debugging   If you want cool formatting you ll need to do it manually

var dump   can do this      This function displays structured information about one or more expressions that includes its type and value  Arrays and objects are explored recursively with values indented to show structure    http   php net manual en function var-dump php

Similar to karim s  but with print r which has a much small output and I find is usually all you need   function PrintR  var        echo   lt pre gt        print r  var       echo   lt  pre gt

This is a little function I use all the time its handy if you are debugging arrays  Its pretty much the same thing Darryl and Karim posted  I just added a parameter title so you have some debug info as what array you are printing  it also checks if you have supplied it with a valid array and lets you know if you didn t   function print array  title  array            if is array  array                 echo  title   lt br  gt                   ---------------------------------   lt br  gt                  lt pre gt                print r  array                echo   lt  pre gt                 END    title   lt br  gt                   ---------------------------------   lt br  gt              else               echo  title   is not an array                  Basic usage     your array  array   array  cat   dog   bird   mouse   fish   gerbil      usage print array  PETS    array     Results   PETS   ---------------------------------    Array        0    gt  cat      1    gt  dog      2    gt  bird      3    gt  mouse      4    gt  fish      5    gt  gerbil    END PETS   ---------------------------------

For nice  amp  readable results  use this   function printVar  var        echo   lt pre gt        var dump  var        echo   lt  pre gt        The above function will preserve the original formatting  making it  more readable in a web browser
