explode based on uppercase?

[scliburn]

Does php have any built in functions to perform an explode or string replace based on upper case characters:

 

Example:

AfghanistanTransnationalIssues

I want to parse into Afghanistan Transnational Issues, without having to write some regex script.

 

Anyone know if this exists, and if yes, what is the function name? I don't think it does, as I've been over the php site pretty good over the past 8 years or so.

This is going to be pretty inefficient depending on how much data you have to analyze but...

 

Grab each letter and do if ($letter == strtoupper($letter))

$letter = " " . $letter;

else

//go to next

 

Sorry for the quick pseudo but I hope you get my idea.

If you do that make sure it isn't just looking for capital letters but capital letters with lower case after and before it, to make sure it is like your example. Also make sure it isn't suppose to be together for whatever reason (can't think of any atm, but im sure there are cases where you put a capital in the word like "McDonalds" or so)

You'll need a regex...

 

<?php
$string = "AfghanistanTransnationalIssues";
$array = preg_split('/([A-Z])/', $string, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
foreach ($array as $key => $value) {
if ($key % 2 == 0) {
    $temp = $value;
}
else {
    $new_arr[$key / 2] = $temp . $value;
}
}
print_r($new_arr);
?>

thanks peeps and thanks for the code example DW.

I like this better

 

<pre><?php

$regex1 = '%([a-z])([A-Z])([a-z])%';
$str1 = 'AfghanistanTransnationalIssues';

$rep1 = preg_replace( $regex1, '$1 $2$3', $str1 );

echo $rep1

?></pre>

And it's more efficient.
