I have this string
../../some/folder/image.png
and it's possible that the string will be
../../../../../../some/folder/image.png
and I want to remove all ../ and add /root/folder/ in front of some/folder/image.png.
How do I do this?
edit
And sometime that string is placed in the middle. I mean it might be like this:
hallo hallo ../../../some/folder/image.png.
You could do the following :
$path = "hello lol ../../some/folder/image.png";
$path = preg_replace("#.*\.\./#", "", $path);
$path = "/root/folder/" . $path;
Depends where you want to use it, but you would do something like this
$path = "../../../../../some/folder/image.png";
$searchFor = substr($path, 0, strpos( $path, "some"));
$path = str_replace($searchFor, "/root/folder/", $path);
I know the preg_replace() is better, but I wanted to share a different answer

I have a variable that stores the location of a temp file:
$file = 'C:\xampp\htdocs\temp\filename.tmp';
How can I explode all this to get filename (without the path and extension)?
Thanks.
Is not the best code but if you confident that this path will be similar and just file name will be different you can use this code:
$str = 'C:\xampp\htdocs\temp\filename.tmp';
$arrayExplode = explode("\\", $str);
$file = $arrayExplode[count($arrayExplode)-1];
$filename = explode('.', $file);
$filename = $filename[0];
echo $filename;
Advice: Watch out on the path contain "n" like the first letter after the backslash. It could destroy your array.
You should use the basename function, it's meant specifically for that.
I am getting directory path in my PHP like below
C:\Users\MAITRII\Desktop\LATEST\a
using code like below
$path = getcwd();
Now I want replace "\" with "/" and want remove C: from string and want output like below
/Users/MAITRII/Desktop/LATEST/a
Let me know if someone can help me for achieve this.
As per my comment Use str_replace function but in backslash case use this pattern '\\', '/'
<?php
$path="C:\Users\MAITRII\Desktop\LATEST\a";
$path = str_replace('\\', '/', $path);
print_r($path);
here is the output
and finally you can remove C: using substr function
$path = substr($path, 2);
please try
$path = 'C:\Users\MAITRII\Desktop\LATEST\a';
$path1 = substr($path, 2);
$path2 = str_replace("\\","/",$path1);
echo $path2;
subsrt will remove first two letters i.e. C:
str_replace will replace \ with /
You will need to add additional \ in str_replace("\\","/",$path1);
OUTPUT is here
Hi i want to know how can i get substring from string after last slash?
In short i want to get the file name from path.
for example i got string like this:
test-e2e4/test-e2e4/test-e2e4/6.png
and i want to get 6.png how can i do that ?
I got dir only and the file name can be all format, it can be also something else then file
Or test-e2e4/test-e2e4/test-e2e4/aaaaa and want to get aaaaa
Regex maybe? Or maybe you know some nice functions which will do it for me ?
In addition to other replies, there's actually a function in PHP to do this: basename. Example:
$string = 'test-e2e4/test-e2e4/test-e2e4/6.png';
$base = basename($string); // $base == '6.png';
$string = 'test-e2e4/test-e2e4/test-e2e4/aaaaa';
$base = basename($string); // $base == 'aaaaa'
$string = '6.png';
$base = basename($string); // $base == '6.png'
Full details here: http://php.net/basename
Do like this..
$yourstring = 'test-e2e4/test-e2e4/test-e2e4/6.png';
$val = array_pop(explode('/',$yourstring)); // 6.png
You can try explode and array_pop functions to work this out:
$str = 'test-e2e4/test-e2e4/test-e2e4/aaaaa.png';
$str = explode('/', $str);
$filename = array_pop($str);
echo $filename; //Output will be aaaaa.png
...Or you can use the following regex:
[^\/]*$
You don't need to use regex for this, you can use substr() to get a portion of the string, and strrpos() to specify which portion:
$full_path = "test-e2e4/test-e2e4/test-e2e4/6.png"
$file = substr( $full_path, strrpos( $full_path, "/" ) + 1 );
substr() returns a portion of the string, strrpos() tells it to start from the position of the last slash in the string, and the +1 excludes the slash from the return value.
I have a path like:
$path='somefolder/foo/bar/lastdir';
and I want to remove the last part, so I have:
$path='somefolder/foo/bar';
Like I went one folder up.
I'm really newbie in php, maybe its just one function, although I can't find it anywhere.
You could try this (tested and works as expected):
$path = 'somefolder/foo/haha/lastone';
$parts = explode('/', $path);
array_pop($parts);
$newpath = implode('/', $parts);
$newpath would now contain somefolder/foo/haha.
use :
dirname(dirname('somefolder/foo/haha/lastone/somescript.php'));
this should return:
somefolder/foo/haha/
This is untested, but try:
$path_array = explode('/',$path);
array_pop($path_array);
$path = implode('/',$path_array);
If you are currently at:
somefolder/foo/haha/lastone/somescript.php
and you want to access:
somefolder/foo/haha/someotherscript.php
just type:
../someotherscript.php
Probably using a regex function would be appropriate if the last part is going to vary. Try
$pattern = '#/.*$#U';
$stripped_path = preg_replace($pattern, '', $original_path);
This will strip everything off the original path string starting from the last forward slash.
You could use a function that explodes() the $path variable into an array and then array_pop to get rid of the last element.
function path($path) {
$arrayPath = explode("/", $path);
$path = array_pop($arrayPath);
return $path = implode("/", $path);
}
The shortest variant in PHP is:
$path = preg_replace('|/[^/]*$|','', $path);
which uses a regular expression.
string '/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg' (length=85)
what i need is just
http://localhost/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg
what is the best way doing it ? i mean useing strlen ? substr_replace ? substr ? im a bit confused what is the best way doing this? becouse there is many ways to do this.
edit* there is no newbie tag :|
// get from database red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg
$image_path = $this->data['products'][0]['image_small'];
$exploded = end(explode('/', $image_path));
$myurl = DOMAIN;
$myfullurl = $myurl."/storage/".$exploded;
// it works!, but let see the comments maybe there is a better way :)
Here is how you can get the image part:
$str = '/home/adam/Projects/red/storag/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg';
$exploded = end(explode('/', $str));
echo $exploded;
Result:
22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg
Now you can concatenate it with whatever eg:
$new_str = 'http://localhost/storage/' . $exploded;
echo $new_str;
Result:
http://localhost/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg
And It is most likely you want to concatenate the image path with your document root which you do like this:
$img_path = $_SERVER['DOCUMENT_ROOT'] . $exploded;
The idea is that you explode the string with explode function by specifying / as delimiter. This gives you array, now you use the end function to get the ending part of the array which is your image actually.
If the path prefix represents your document root path, then you can do this to strip it:
$path = '/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg';
$_SERVER['DOCUMENT_ROOT'] = '/home/adam/Projects/red/';
if (substr($path, 0, strlen($_SERVER['DOCUMENT_ROOT'])) === $_SERVER['DOCUMENT_ROOT']) {
$uriPath = substr($path, strlen(rtrim($_SERVER['DOCUMENT_ROOT'], '/')));
echo $uriPath;
}
I suggest you check if the string contains /home/adam/Projects/red, and if it does, you use substr to get the part after it, and you glue it with http://localost.
$path = '/home/adam/Projects/red/storage/*snip*.jpg';
$basePath = "/home/adam/Projects/red";
if (strpos($path, $path) !== false)
$url = 'http://localhost' . substr($path, strlen($basePath));
This one's pretty much the easiest
str_replace(
"/home/adam/Projects/red",
"http://localhost",
"/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg"
);
$string = '/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg';
str_replace('/home/adam/Projects/red', 'http://localost', $string)
