Can explode in PHP help me split by two factors?

The usual:

$data = 'hello world&cool&stuff&here';

$explode = explode('&', $data); // returns array with hello world, cool, stuff, here

Now this data

$data = 'hey this is a beautiful day #content_start#The World is Beautiful#content_end#';

How can i extract "The World is Beautiful" from the above string?

Running explode('#content_start', $data); and then explode('#content_end', $data); ? Or is there an easier and more fit way.

Try THIS....

$data = 'hey this is a beautiful day #content_start#The World is Beautiful#content_end#';
echo substr(strstr(implode(explode("end#",implode("{",explode("start#", implode(explode("#content_", $data)))))), '{'), 1);

The idea you had would work perfectly fine.

Just do it like that:

$data = 'hey this is a beautiful day #content_start#The World is Beautiful#content_end#';
$first = explode('#content_start#', $data);
$second = explode('#content_end#', $first[1]);
echo $second[0];

The first explode will return an array of strings, where the first ($first[0]) will be hey this is a beautiful day and the second ($first[1]) will be The World is Beautiful#content_end#. Then you can use the second explode to have the result you wanted.

However, a more readable approach would be to use a RegEx to match your searched pattern and literally search for your string. The code would then be:

$data = 'hey this is a beautiful day #content_start#The World is Beautiful#content_end#';
$matches = array();
preg_match('/#content_start#(.*)#content_end#/', $data, $matches);
echo $matches[1];

This is a job for regular expressions:

$data = 'hey this is a beautiful day #content_start#The World is Beautiful#content_end#';
preg_match( '/#content_start#(.*)#content_end#/s', $data, $matches );
print_r( $matches );

This will display:

Array
(
    [0] => #content_start#The World is Beautiful#content_end#
    [1] => The World is Beautiful
)

So $matches[0] contains the original matched string, and $matches[1] contains the match.

Using explode is not the best option here.

You should better use strpos and substr:

$start = '#content_start#';
$end   = '#content_end#';
$startPos = strpos($data, $start) + strlen($start);
$length = strpos($data, $end) - $startPos;
$result = substr($data, $startPos, $length);

Why not using this?

$data = 'hey this is a beautiful day #content_start#The World is Beautiful#content_end#';
$parts = explode('#', $data);
echo $parts[2];
