How to concatenate string continuously in php? - php

Question

<?php
$test = ' /clothing/men/tees';
$req_url = explode('/', $test);
$c = count($req_url);
$ex_url = 'http://www.test.com/';
for($i=1; $c > $i; $i++){
echo '/'.'<a href="'.$ex_url.'/'.$req_url[$i].'">
<span>'.ucfirst($req_url[$i]).'</span>
</a>';
//echo '<br/>'.$ex_url;....//last line
}
?>
OUTPUT - 1 //when comment last line
/ Clothing / Men / Tees
OUTPUT - 2 //when un-comment last line $ex_url shows
/ Clothing
http://www.test.com// Men
http://www.test.com// Tees
http://www.test.com/
1. Required output -
In span - / Clothing / Men / Tees and last element should not be clickable
and link should created in this way
http://www.test.com/clothing/Men/tees -- when click on Tees
http://www.test.com/clothing/Men -- when click on Men
...respectively
2. OUTPUT 2 why it comes like that

Answer 1

Try this:
<?php
$test = '/clothing/men/tees';
$url = 'http://www.test.com';
foreach(preg_split('!/!', $test, -1, PREG_SPLIT_NO_EMPTY) as $e) {
$url .= '/'.$e;
echo '/<span>'.ucfirst($e).'</span>';
}
?>
Output:
/Clothing/Men/Tees
HTML output:
/<span>Clothing</span>/<span>Men</span>/<span>Tees</span>

Answer 2

Try using foreach() to iterate the array and you'll have to keep track of the path after the url. Try it like so (tested and working code):
<?php
$test = '/clothing/men/tees';
$ex_url = 'http://www.test.com';
$items = explode('/', $test);
array_shift($items);
$path = '';
foreach($items as $item) {
$path .= '/' . $item;
echo '/ <span>' . ucfirst($item) . '</span>';
}

Answer 3

Try this.
<?php
$test = '/clothing/men/tees';
$req_url = explode('/', ltrim($test, '/'));
$ex_url = 'http://www.test.com/';
$stack = array();
$reuslt = array_map(function($part) use($ex_url, &$stack) {
$stack[] = $part;
return sprintf('%s', $ex_url, implode('/', $stack), ucfirst($part));
}, $req_url);
print_r($reuslt);

Answer 4

<?php
$sTest= '/clothing/men/tees';
$aUri= explode( '/', $sTest );
$sBase= 'http://www.test.com'; // No trailing slash
$sPath= $sBase; // Will grow per loop iteration
foreach( $aUri as $sDir ) {
$sPath.= '/'. $sDir;
echo ' / '. ucfirst( $sDir ). ''; // Unnecessary <span>
}
?>
