I'm trying to replace strings having no quotes+HTML tag with those having quotes.
Example: worlds in <i>worlds<i> to be replaced with World's. So, <i>worlds<i> becomes World's.
I'm using the following code, but it doesn't take into account the '(quotes).
preg_replace('/\b' . preg_quote('worlds') . '\b/i', '<i>$0</i>', 'World's');
you have to escape the ' by placing \ before. Try this:
preg_replace('/\b' . preg_quote(worlds) . '\b/i', '<i>$0</i>', 'World\'s');

I have a link that is sent throw some PHP code:
echo "<a href='" . $galerry . "#" . apastro(get_title($primid)) . "' class='linkorange'>voir sa galerie</a>";
$galerry links to another page.
get_title($primid) is the id of a specific element in $galerry page.
And the mechanism works fine until one of the elements id has a single quote in it. Which makes sense as it would interrupt the echo function.
This is why I have the apastro function:
function apastro($phrase){
$phrase1 = str_replace("'", "\'", $phrase);
return $phrase1;
}
Yet, the \ before the single quote isn't helping...
So let's say the link redirects to the element with id="l'aro" on the page something.php. Then the URL will be something.php#l\.
it would interrupt the echo function
It wouldn't. It would break a string literal delimited by ' characters, but your string literal is delimited with " characters. In this case, it is breaking the HTML attribute value which is delimited by ' characters.
\ is not an escape character for URLs or HTML.
Use urlencode to make a string safe to put into a URL.
Use htmlspecialchars to make a string safe to put into an HTML attribute.
$title = get_title($primid);
$urlsafe_title = urlencode($title);
$url = $galerry . "#" . $urlsafe_title;
$htmlsafe_url = htmlspecialchars($url, ENT_QUOTES | ENT_HTML5);
echo "<a href='$htmlsafe_url' class='linkorange'>voir sa galerie</a>";
If you're looking to escape single quotes only, use double backslashes, as follows
$str = str_replace("'", "\\'", $str);
When i echo "$time"; - The output is 2015-07-27 18:17:47
But i need to output as "2015-07-27 18:17:47".
I have been trying various string concatenations such as : echo "."$time"."; But couldn't get the desired output? What is the best way to do it?
Try this concatenation
echo '"' . $time . '"';
or use printf() like so
printf('"%s"', $time);
Just escape them:
echo "\"$time\"";
You could also use single around the double quotes:
echo '"' . $time . '"';
See here for more info on escape sequences when using double quotes.
I'm sure I'm missing something obvious here: the following is echoing lat-long variables from MySQL, and the longitude variable begins with a minus sign, which prevents the echo statement from reading it and all that follows it. I'm sure there is a way to clean/escape that but just can't work it out.
echo "http://maps.google.com/maps?ll=" . $row['latitude'] . "," . $row['longitude'] . " target=_new>View in Google Maps";
This is output from a PDO query and testing passing the lat-long into Google Maps.
As I understand, it's a link?
Then, use urlencode for string.
The minus signs are not a problem. You may need to urlencode() because of the comma, but you need quotes around the URL in the href as well:
echo '<br /><a href="http://maps.google.com/maps?ll='
. urlencode($row['latitude'] . ',' . $row['longitude'])
. '" target="_new">View in Google Maps</a>';
I have a PHP echo statement:
echo "stores[".$row['BarID']."] = [". $row['BarName'] . ", " . $row['Address']. ",". $row['City']. "," . $row['State']. " 0". $row['ZipCode']. "," . $row['PhoneNumber']. ",". $row['Lattitude']. ",".$row['Longitude']. "]". ";<br>";
which outputs:
stores[0] = [The Ale 'N 'Wich Pub , 246 Hamilton St ,New Brunswick,NJ 08901,732-745-9496 ,40.4964198,-74.4561079];
BUT I WOULD LIKE THE OUTPUT IN DOUBLE QUOTES SUCH AS:
stores[0]=["The Ale 'N 'Wich Pub", "246 Hamilton St, New Brunswick, NJ 08901", "732-745-9496 Specialty: Sport", "40.4964198", "-74.4561079"];
I Have looked at the PHP String Functions Manual on PHP site but still don't understand how i can implement it. Your help is appreciated.
The keyword you miss is "escaping" (see Wiki). Simplest example:
echo "\"";
would output:
"
EDIT
Basic explanation is - if you want to put double quote in double quote terminated string you MUST escape it, otherwise you got the syntax error.
Example:
echo "foo"bar";
^
+- this terminates your string at that position so remaining bar"
causes syntax error.
To avoid, you need to escape your double quote:
echo "foo\"bar";
^
+- this means the NEXT character should be processed AS IS, w/o applying
any special meaning to it, even if it normally has such. But now, it is
stripped out of its power and it is just bare double quote.
So your (it's part of the string, but you should get the point and do the rest yourself):
echo "stores[".$row['BarID']."] = [". $row['BarName'] . ", " . $row['Address'] .
should be:
echo "stores[".$row['BarID']."] = [\"". $row['BarName'] . "\", \"" . $row['Address']. "\"
and so on.
I have the following variable which returns my URL as needed. But i need to run str_replace() on it to replace a character before echoing it into my HTML code.
$url = str_replace("%3A", ":", " . nl2br( $row['url']) . ");
As it stands the " . nl2br( $row['url']) . " contains %3A instead of the colon in the URL and for some reason its rendering my links like this
http://www.mydomain.com/http%3A//url.com
I'm not really sure what your question is, but it looks like this is what you want:
$url = urldecode($row['url']);
The %3A is a URL encoded colon (:).
