[SOLVED] 7/2JF => 7, 2 and JF

[chiprivers]

I think this is probably a regular expression task but I am not too sure how to implement it! I need to seperate a string into three new strings.  The original string will be an int, followed by slash and another in then there may be some letters.  I would like this to be seperated into the three seperate strings like this:

 

$string = "7/2JF";

 

$x = 7;

 

$y = 2;

 

$z = "JF";

 

or another exxample:

 

$string = "3/1";

 

$x = 3;

 

$y = 1;

 

$z = "";

 

Any help much appreciated ;0)

Yep, REGEX would be the way to go.

Something like this:

<?php

$string = "7/2";

preg_match("#([\d]+)/([\d])([A-Z]+){0,}#", $string, $matches);

echo '<pre>' . print_r($matches, true) . '</pre>';

echo '
x = ' . $matches[1] . '<br />
y = ' . $matches[2] . '<br />
z = ' . (empty($matches[3]) ? 'N/A' : $matches[3]);

?>

<pre>
<?php
$string = '7/2JF';
$data = preg_split('%(?:/|(?<=\d))%', $string);
print_r($data);

?>
</pre>

Umm, you can clearly see who's a master in regex here.

<?php

print_r($data);

?>
</pre>

 

Thanks for help, this works fine for single digit ints but the ints before and after the slash may be two or three digits and at the moment it is creating a new array entry for each digit.

<pre>
<?php
$tests = array(
	'7/2JF',
	'3/1',
	'12345/6789',
	'12345/67890ABC'
);
foreach ($tests as $test) {
	$data = preg_split('%(?:/|(?<=\d)(?=\D|\z))%', $test);
	print_r($data);
}
?>
</pre>

perfect, many thanks.

 

I must start learning some regec cause I am sure it would make a lot of other problems I face a lot simpler!
