I'm building a gallery application and I've been having Issues finding out If there Is a way I can put HTML around each PHP array value In my case images,
I believe that If I echo It I'll get the values as text. I don't want to echo the values as text any options?
Thanks in advance.

Answer 1

If I understand correctly the following may be of some help, If you want to display the images in HTML you could use something like the following.
$images = array(
"1" => "image1.png",
"2" => "image2.jpeg",
"3" => "image3.gif"
);
foreach ($images as $key => $image) {
echo "<img src=\"{$image}\" alt=\"image {$key}\"/>";
}
and if you want to place the images inside HTML and back into your array you can use the following.
$images = array(
"1" => "image1.png",
"2" => "image2.jpeg",
"3" => "image3.gif"
);
foreach ($images as $key => $val) {
$images[$key] = "<img src=\"{$val}\" alt=\"image {$key}\"/>";
}

Not sure if this is just a "coders block", but it's very simple. grab the array, iterate it, wrap the output of each array element in a div and echo it back to the requesting page.
foreach($array as $item):
echo '<div>', $item ,'</div>';
endforeach;

Option 1
You seem to be looking for array_walk:
bool array_walk(array &$Input, callable $Fn [, mixed $extra = null ])
Applies the user-defined function Fn to
each element of the array Input, optionally
passing it the user-specified object $extra.
This is an example of wrapping every element of the array between two user-specified values.
<?php
$arry = array(
'pear',
'orange',
'banana',
);
array_walk($arry, function(&$item, $key, $data) {
$item = $data['before'].$item.$data['after'];
}, array(
'before' => 'this is a ',
'after' => ' squash.',
));
print_r($arry);
?>
Output:
Array
(
[0] => this is a pear squash.
[1] => this is a orange squash.
[2] => this is a banana squash.
)
Option 2
Another option could be that of using preg_replace_callback to perform a bulk replace on each element. This allows greater flexibility both in specifying what to replace, and how to replace it:
<?php
$arry = array(
'pear squash',
'squishy orange',
'squoshed banana',
);
// FIRST - wrap everything in double round brackets
$arry = preg_replace_callback('/^.*$/', function($matches){
return "(($matches[0]))";
}, $arry);
// SECOND - convert anything like "SQUASH" (but with whatever letter instead
// of the "A" - to "juice":
$arry = preg_replace_callback('/(.*)squ(.)sh(.*)/', function($matches){
// $matches[2] contains the whatever letter.
return $matches[1].'juice'.$matches[3];
}, $arry);
print_r($arry);
returns now
Array
(
[0] => ((pear juice))
[1] => ((juicey orange))
[2] => ((juiceed banana))
)
