link is : info.php?Submit=#img.png
so
<?php echo $_GET["Submit"]; ?>
but this wil show : #img.png
how to remove the "#" from the name so it shows : img.png ??
thanks
$_GET["Submit"] will not contain that, since # marks the beginning of the 'fragment', which does not get passed to the server.
If the link is info.php?Submit=%23img.png, then you can trim it like this:
<?php echo substr($_GET["Submit"], 1); ?>
Well, you could always modify the sender code to exclude the leading # (or %23 as #Cal pointed out).
Otherwise, try one of these:
//substring [1:len]
$yourString = substr($_GET["Submit"], 1);
//replace "#" with ""
$yourString = str_replace("%23", "", $_GET["Submit"], 1); //1 is the limit of #s to remove
//parse the URL, then get the path
$yourString = parse_url($_GET["Submit"], PHP_URL_PATH);
Try this, if you are sure that the first character is either a # or the encoding of one (%23):
<?php echo substr(urldecode($_GET["Submit"]),1); ?>

I wrote a code which adds hyperlink to all plain text where it finds http:// or https://. The code works pretty well for https://www.google.com and http://yahoo.com. It converts these text into clickable hyperlink with correct address.
<?php
function convert_text_to_link($str)
{
$pattern = "/(?:(https?):\/\/([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])/i";
return preg_replace($pattern, "<a href='$0' target='_blank'>$0</a>", $str);
}
$str = "https://www.google.com is the biggest search engine. It's competitors are http://yahoo.com and www.bing.com.";
echo convert_text_to_link($str);
?>
But when my code sees www.bing.com, though it adds hyperlink to it but the href attribute also becomes www.bing.com. There is no http:// prepended it. Therefore the link becomes unusable without the link http://localhost/myproject/www.bing.com will go nowhere.
How can I add http:// to www.bing.com so that it should become http://www.bing.com?
Here is your function. Try this.
function convert_text_to_link($str) {
$pattern = '#(http)?(s)?(://)?(([a-zA-Z])([-\w]+\.)+([^\s\.]+[^\s]*)+[^,.\s])#';
return preg_replace($pattern, '$0', $str);
}
You should try and check if this works:
window.location = window.location.href.replace(/^www./, 'https:');
might be you will get your solution.
I just got to know about some other approaches too, you can try them out as per your code and requirements:
1.
str_replace("www.","http://","$str");
The test here is case-sensitive. This means that if the string is initially this will change it to http://Http://example.com which is probably not what you want.
try regex:
if (!$str.match(/^[a-zA-Z]+:\/\//))
{
$str = 'http://' + $str;
}.
hope this helps.
i use (str_replace) function to replace ##ID## in youtube url with this regular expression : (?P<id>[a-z-A-Z_0-9]+)
so i use this code to do this :
<?php
$urlbase = 'https://www.youtube.com/watch?v=##ID##';
$lastchange = str_replace('##ID##', '(<id>[a-z-A-Z_0-9]+)', $urlbase);
echo $lastchange;
?>
i get the output in the browser like this : https://www.youtube.com/watch?v=(?P[a-z-A-Z_0-9]+), its looks like <id> not show up !
i try this simple code :
<?php
echo "This is my <id>";
?>
but i just get this is my in the browser !
What's the probleme ? and how i can fix it , thanks
is being interpreted as HTML so your browser is parsing it and since it is not a renderable element, it shows nothing. Try:
<?php
echo "This is my <id>
?>
As for the str_replace, it's doing exactly what the function is supposed to be doing. If you're looking to use regular expressions in string replacements, use preg_replace
The tag <id> is being removed by your browser. It is really there if you watch the source code. Maybe you should try:
$urlbase = 'https://www.youtube.com/watch?v=##ID##';
$lastchange = str_replace('##ID##', '(<id>[a-z-A-Z_0-9]+)', $urlbase);
echo urlencode( $lastchange );
Problem is with the line:
$lastchange = str_replace('##ID##', '(<id>[a-z-A-Z_0-9]+)', $urlbase);
str_replace does not use regex.
You will need preg_replace
$pattern = '(<id>[a-z-A-Z_0-9]+)'
$replacement = '##ID##'
$string = $urlbase
$lastchange = preg_replace($pattern, $replacement, $string);
Also < and > are html entities which means they are reserved chars for HTML they have some special meanings if you want to show them then you must use there entity name eg < and > in your case respectively.
<?php
echo " echo "This is my <id>";
?>
I'm trying to strip a variable suffix off my Wordpress titles, basically a bunch of hastags from posts imported from Instagram that are preceeded by an hyphen and I've come up with something like this:
<?php
$titleoutput = get_the_title($ID);
$titleoutputstrip = preg_replace("/\-/", "", $titleoutput);
echo $titleoutputstrip;
?>
But it doesn't seem to be working.
Can anyone help me out?
Thanks in advance!
<?php
$titleoutput = get_the_title($ID);
$titleoutputstrip = ltrim($titleoutput , '-'); // ltrim for begining rtrim for end
echo $titleoutputstrip;
?>
I finally nailed it with:
<?php
$titleoutput = get_the_title($ID);
$titleoutputstrip = preg_replace('/\ #[^.]+$/','',$titleoutput);
echo $titleoutputstrip;
?>
The hyphen was giving me problems because it's actually a dash "–" or something like that so I just set it to look for the first hashtag and erase the contents to the end.
I have this test.php where i have this info :
callername1 : 'Fernando Verdasco1'
callername2 : 'Fernando Verdasco2'
callername3 : 'Fernando Verdasco3'
callername4 : 'Fernando Verdasco4'
callername5 : 'Fernando Verdasco5'
this page automatically changes that name every 10 min
In this another page test1.php
I need a php code that takes only the name of the callername3 and echo'it
Fernando Verdasco3
I've tried this like so test1.php?id=callername3
<?php
$Text=file_get_contents("test.php");
if(isset($_GET["id"])){
$id = $_GET["id"];
parse_str($Text,$data);
echo $data[$id];
} else {
echo "";
}
?>
but no result.
Is there any other option?
If i have "=" instade of ":"
callername1 = 'Fernando Verdasco1'
callername2 = 'Fernando Verdasco2'
callername3 = 'Fernando Verdasco3'
callername4 = 'Fernando Verdasco4'
callername5 = 'Fernando Verdasco5'
And i use This php Code it works
<?php
$Text=file_get_contents("test.php")
;preg_match_all('/callername3=\'([^\']+)\'/',$Text,$Match);
$fid=$Match[1][0];
echo $fid;
?>
i need this to work with ":"
Help?
You should store data in a file with the .php extension, since it's not executable PHP. I looks like you're going for the JSON syntax.
Since you need it to work with ':' I assume, for whatever reason, you can't change the format. Your example with '=' works because of the regexp:
preg_match_all('/callername3=\'([^\']+)\'/',$Text,$Match);
This says, match text like callername3= followed by a ' followed by one or more chars that are not a ' followed by a final '. Everything between the 's is stored in $Match[1][0] (if there were more parts in brackets they be stored in $Match[2][0], etc).
Your example doesn't work since it doesn't account for the spaces before and after the = sign. But we can fix that up and change it to work for : like this:
preg_match('/callername3\s*:\s*\'([^\']+)\'/',$Text,$Match);
echo $Match[1] ."\n";
This displays:
Fernando Verdasco3
And what that regular expression is match text that start callername3 followed by any amount of whitespace (that's the \s*) followed by a :, followed by any amount of whitespace, followed by a name in quotes (that is stored in $Match[1], this is the area of the regular expression enclosed in parenthesis).
I've also used just preg_match because it looks like you only need to match one example.
There is a rather simple approach to tihs:
$fData = file_get_contents("test.php");
$lines = explode("\n", $fData);
foreach($lines as $line) {
$t = explode(":", $line);
echo trim($t[1]); // This will give you the name
}
I have a variable $link_item, it's used with echo and gives the strings like
<span class="name">Google</span>http://google.com
How to remove "<span class="name">Google</span>" from string?
It should give just "http://google.com".
Heard it can be done with regex(), please help.
Without regex:
echo substr($link_item, stripos($link_item, 'http:'))
But this only works if the first part (i.e. <span class="name">Google</span>) never contains http:. If you can assure this: here you go :)
Reference: substr, stripos
Update:
As #Gordon points out in his comment, my code is doing the same as strstr() already does. I just put it here in case one does not read the comments:
echo strstr($link_item, 'http://');
$string = '<span class="name">Google</span>http://google.com';
$pieces = explode("</span>",$string);
//In case there is more than one span before the URL
echo $pieces[count($pieces) -1];
Solved:
$contents = '<span class="name">Google</span>http://google.com';
$new_text = preg_replace('/<span[^>]*>([\s\S]*?)<\/span[^>]*>/', '', $contents);
echo $new_text;
// outputs -> http://google.com
Don't use a regex. Use a HTML parser to extract only the text you want from it.
Made myself
$link_item_url = preg_replace('#<span[^>]*?>.*?</span>#si', '', $link_item);
This will remove any <span + something + </span> from variable $link_item.
Thanks for all.
