Converting Strings to Arrays
Sometimes, arrays are not used to store information; instead, a string is used. The single values are all within the string, but are separated by a special character. One example for this is the comma separated values (CSV) format. Turning a String into an Array (explode.php) <?php $csvdata = 'Sams Publishing,800 East 96th Street,Indianapolis,Indiana,46240'; $a = explode(',', $csvdata); $info = print_r($a, true); echo "<pre>$info</pre>"; ?> The PHP function explode() creates an array out of these values; you just have to provide the character(s) at which the string needs to be split. The browser then shows this output: Array ( [0] => Sams Publishing [1] => 800 East 96th Street [2] => Indianapolis [3] => Indiana [4] => 46240 ) |
