Similar to the creation of an array, there are three ways to display the output of an array.
1. for loop (recommended learning: PHP video tutorial)
<?php
$ms_office = array(
'word',
'excel',
'outlook',
'access'
);
for($i=0; $i<4; $i++)
{
echo "数组第".($i+1)."个元素是：";
echo $ms_office[$i];
echo "<br>";
}
?>数组第1个元素是：word 数组第2个元素是：excel 数组第3个元素是：outlook 数组第4个元素是：access
Suddenly One of the interesting things about PHP is that after it uses $ to define a variable, no matter where you go, as long as you use the variable, the variable name will be preceded by $.
2. Use the foreach loop statement
<?php
$ms_office = array(
'word',
'excel',
'outlook',
'access'
);
foreach($ms_office as $software)
{
echo $software;
echo "<br>";
}
?>word excel outlook access
defines an array without specifying its index, so the default integer form is used.
3. Use print_r() to display array elements
<?php $ms_office = array( 'word', 'excel', 'outlook', 'access' ); print_r($ms_office); ?>
Array ( [0] => word [1] => excel [2] => outlook [3] => access )
Add echo "e03b848252eb9375d56be284e690e873"; in front of print_r() to get an array structure with a clearer format.
You can also add code to output the end tag "bc5574f69a0cba105bc93bd3dc13c4ec" after print_r().
Array ( [0] => word [1] => excel [2] => outlook [3] => access )
HTML tag e03b848252eb9375d56be284e690e873 can define pre-formatted text. e03b848252eb9375d56be284e690e873bc5574f69a0cba105bc93bd3dc13c4ecYou can display the spaces, carriage returns, line feeds, and Tab keys in the text between them, that is, display them according to the original layout of the text.
