Manipulating Strings in PHP with Functions - php

Question

I searched every single str_replace, preg_replace, substr on StackOverflow and can't wrap my head around this.
The strings in my data are as such: "010758-01-700" or "860862-L-714". These are just examples.
These strings are 's
Instance 1:
010758-01-700
/ImageServices/image.ashx?itemid=010758&config=01&format=l&imagenumber=1
If you look carefully at the URL and the string above it, I need to split this as "01075&config=01" and drop "-700" from the string to return a value I can insert into the URL
Instance 2:
860862-L-714
/ImageServices/image.ashx?itemid=870078&color=001&format=l&imagenumber=1
I need to split this as "860862&&color=714" and drop all instances of "-XXS-, -XS-, -S-, -M-, -L-, -XL- ,-XXL-" for the string to return a value I can insert into the URL
There are strings that look like this throughout the data, 860862-L-714, 860862-M-999, 860862-XS-744. These are variations of product with the same name but different
I have tried str_replace("-", "&config=", {ItemNo[1]}) but it returns 010758&config=01&config=700
I'd need to contain this all into a function that I can call into the URL
myFunction({ItemNo[1]})
Then I can setup the URL as so /ImageServices/image.ashx?itemid=
myFunction({ItemNo[1]})&format=l&imagenumber=1
and if my logic is correct, it should work. I'm using WP All Import to import XML data.
How do I create a function that will manipulate the string based on both instances above and output the results I'm trying to achieve?
Ok - based on the responses, I've solved the first instance to get the correct url to display - $content being the ItemNo
<?php
function ItemNoPart1 ( $content ) {
$content1 = explode("-", $content);
return $content1[0];
}
function ItemNoPart2 ( $content ) {
$content2 = explode("-", $content);
return $content2[1];
}
?>
/ImageServices/image.ashx?itemid=[ItemNoPart1({ItemNo[1]})]&config=[ItemNoPart2({ItemNo[1]})]&format=l&imagenumber=1
Now I just need to figure out how to do part 2 and combine it all into 1 function.

Answer 1

Don't use str_replace, use explode instead:
$str = '010758-01-700';
$chunks = explode( '-', $str );
By this way, resulting $chunks is an array like this:
[0] => 010758
[1] => 01
[2] => 700
So, now you can format desired URL in this way:
$url = "/ImageServices/image.ashx?itemid={$chunks[0]}&config={$chunks[1]}&format=l&imagenumber=1"
Your desired function is this:
function myFunction( $itemID )
{
$chunks = explode( '-', $itemID );
return "/ImageServices/image.ashx?itemid={$chunks[0]}&config={$chunks[1]}";
}
... but, really you want a function for this stuff?

Here's some psuedo code that may lead you in the right direction. The idea is to build out an array that contains all of the possible pieces of data from our string.
I've used a given constant of /ImageServices/image.ashx? to split upon, as we know the URL of our endpoint.
// explode our string into multiple parts
$parts = explode('/ImageServices/image.ashx?', $str);
// we know that the string we need to parse as at the index of 1
parse_str($parts[1], $parsed);
//$wanted will contain all of the data we can possibly need.
$wanted = array($parts[0], $parsed);
This will yield an array that looks like the following:
array (
0 => '860862-L-714 ',
1 =>
array (
'itemid' => '870078',
'color' => '001',
'format' => 'l',
'imagenumber' => '1',
),
)
Now you can perform your conditionals such as when you need to look for color and create a specific URL structure:
if(array_key_exists('color', $wanted[1]){
//create our custom sting structure here.
}
Hopefully this helps.
