I was asked how to get the version of PHP , this was due to the minimum requirements of a script stating PHP 5 and a user wanted to know how he could check what his host supplied.
This is the simplest version, save as version.php, upload and then open it in your web browser.
<?php
echo phpversion();
?>
On my XAMPP installation it displayed 5.2.6
This will display the version of PHP you are using
<?php
echo “<br>I am using “.PHP_VERSION;
?>
The test text file was actually an article, this example will look for full stops in the text and output each line as a new line.
<?php
$file = file_get_contents(”test.txt”);
$contents = explode(”.”,$file);
foreach ($contents as $content)
{
echo “$content<br/>”;
}
?>
Read a text file into an array
<?php
$file = file_get_contents(”test.txt”);
// Place the contents of test.txt in an array
$contents = explode(”\n”,$file);
foreach ($contents as $content)
{
echo “$content”;
}
?>
Add to an array using array_push
<?php
$search = array(”google”,”yahoo”,”live”,”google”,”yahoo”,”google”);
print_r($search);
print “<br>”;
//lets add a couple of values and print them out again
array_push($search,”google”,”live”);
print_r($search);
?>
The result will be
Array ( [0] => google [1] => yahoo [2] => live [3] => google [4] => yahoo [5] => google )
Array ( [0] => google [1] => yahoo [2] => live [3] => google [4] => yahoo [5] => google [6] => google [7] => live )
