Issue replacing forward slash in string (php)

I figured out a solution! Not that it explains some of the weird str_replace activity that I was seeing, so if anyone can explain that please do.

But to get around the original issue I was experiencing - The line

$filepath = str_replace($site_url.'/', '', $attachment->image_src_large[0]);

was only having an effect on either back or front end but not both because $attachment->image_src_large[0] was different for each. On front end I would get https://... but on back end, for whatever reason, I would get http://....

So I expanded $site_url = get_site_url(); to be:

$site_url = get_site_url();
  if (strpos($site_url, 'https') !== false){
    $ssl_site_url = $site_url;
    $plain_site_url = str_replace("https", "http", $site_url);
    } else {
    $plain_site_url = $site_url;
    $ssl_site_url = str_replace("http", "https", $site_url);
    }

and then did a str_replace() for both strings. Might be overkill but it will work no matter what protocol $attachment->image_src_large[0] turns out to be.

PHP str_replace for back slash

Your best chance is to do a mysql replace query:

Change the value in the query:

SELECT REPLACE('http://yourdomain.com', 'http', 'https');

You might also try this instead:

UPDATE table
SET field_name = replace(field, 'http, 'https')

How to replace last backward slash with forward slash PHP

Here is a solution using PHP's string functions instead of regex.

Do this:

$url = 'C:\wamp\www\chm-lib\sekhelp_out\HTML\AS_BUILD.htm';
$pos = strrpos($url, '\\');
$url = substr_replace($url, '/', $pos, 1);

echo $url;

To get this:

C:\wamp\www\chm-lib\sekhelp_out\HTML/AS_BUILD.htm

Explanation:

1. Get the position of the last \ in the input string using strrpos()
2. Replace that with / using substr_replace()

Note

It is important to pass '\\' instead of '\' to strrpos() as the first \ escapes the second.

Also note that you can shorten the code above to a single line if you prefer, but I thought it would be easier to understand as is. Anyway, here is the code as a one-liner function:

function reverseLastBackslash($url) {
    return substr_replace($url, '/', strrpos($url, '\\'), 1);
}

how to remove space and replace forward slash in php

A simple str_replace can do this:

$var = "A/P/ 20014/03 /12/4098 ";
$var = str_replace(array('/', ' '), array('-', ''), $var);
echo $var;

Illustration:

                        search for        replacement
$var = str_replace(array('/', ' '), array('-', ''), $var);
                          ^    ^           ^    ^
                          |----|-----------|    |
                               |----------------|
