replace comma from string

[ibnclaudius]

How can I replace the comma from a string like this:

 

You, like this => You like this

You, Derp, like this => You and Derp like this

You, Derp, Derpina, like this => You, Derp and Derpina like this

You, Derp, Derpina, Derpson, like this => You, Derp, Derpina and Derpison like this

preg_replace('/^(.+)[\,]+([ \w]*)$/','\1\2',$e);

shoudl do the trick will remove the last , in any statement

ibnclaudius, the list you've shown us, do you have the code that creates that list? Or is this from a database as a string or scraped from a page?

 

If it's the latter, this will work:

<?PHP

  $string = 'You, Paul, Peter, Chris, like this';
  
  //### Explode the string to an array
  $people = explode(',', $string);
  //### Count array length
  $countPeople = count($people);
  
  //### If the are 2 or more name in the array, we use the code below
  if($countPeople > 2) {
    //### Merge the last name with the "like this" text
    $lastName = $people[$countPeople-2].$people[$countPeople-1];
    //### Assign the second last name
    $secondLastName = $people[$countPeople-3];
    
    //### Remove the last 3 elements of the array
    array_splice($people, $countPeople-3);
   
    //### Add the new ending of the list
    $people[] = $secondLastName.' and '.$lastName;
    
    //### Implode the array with commas to make the list again
    $people = implode(',', $people);
    
  //### If there is only 1 name in the array, just remove the comma
  } else {
    //### Remove the comma from the string
    $people = str_replace(',','',$string);
  }  
  
  echo $people;
  
?>

 

If you have the actual code that creates the list, we could probably help you modify it to fix your issue.

Here's my code:

 

if ($count_school_update_likes > '0')
{
$likers = '';

if ($count_school_update_liked == "1")
{
	$likers .= 'You, ';
}

if ($count_school_update_likes > '1')
{
	$i = 0;

	foreach ($get_school_update_likes->result_array() as $liker)
	{
		$likers .= '<a id="' . $liker['user_id'] . '" href="' . $liker['user_id'] . '">' . $liker['user_name'] . '</a>, ';

		$i++;

		if ($i == 2)
		{
			$count_school_update_likes = $count_school_update_likes - 3;

			if ($count_school_update_likes > "0")
			{
				$likers .= ' and <a id="stream-updates-item-likes-view" href="#">' . $count_school_update_likes . ' others</a> ';
			}

			break;
		}
	}
}

$likers .= ' like this.';

echo preg_replace("/,([^,]*)$/", " $1", $likers); //is not working correctly
}

 

Here is all the possibles outputs I would like to have:

 

You, like this => You like this

You, Derp, like this => You and Derp like this

You, Derp, Derpina, like this => You, Derp and Derpina like this

You, Derp, Derpina, Derpson1, Derpson2, Derpson3, Derpson4, like this => You, Derp, Derpina and other 4 like this

Derp, like this => Derp like this

Derp, Derpina, like this => Derp and Derpina like this

Derp, Derpina, Derpson, like this => Derp, Derpina and Derpson like this

Derp, Derpina, Derpson1, Derpson2, Derpson3, Derpson4, like this => Derp, Derpina, Derpson1 and other 3 like this

Is there any reason you couldn't just load all the values into one array and do this?

 

$last = count($likers) > 1 ? ' and ' .array_pop($likers) : '';
$likers = implode(', ', $likers);
echo $likers . $last . ' like this.';

[ibnclaudius]

No, but how am I going to do the "and 999 others like this"?

[Pikachu2000]

I'm sure I can figure something out for that, but it'll have to wait until after I eat . . .

[ibnclaudius]

When i ran:

 

$likers = $get_school_update_likes->result_array();
$lastLiker = count($likers) > 1 ? ' and ' . array_pop($likers) : '';
$likers = implode(', ', $likers); 

echo $likers . $lastLiker . ' like this.';

 

i got this:

 

A PHP Error was encountered

Severity: Notice

Message: Array to string conversion

Filename: libraries/action.php

Line Number: 230

Array and Array like this

 

And:

 

print_r($likers)

 

outputs something like this:

 

Array ( [0] => Array ( [user_id] => 3 [user_name] => Derp ) [1] => Array ( [user_id] => 4 [user_name] => Derpina ) ) 

[ibnclaudius]

A preg_replace like this would also work:

 

if ($count_school_update_likes == '1')
{
//remove last comma from $likers
}
else if ($count_school_update_likes > '1')
{
//remove last comma from $likers and replace the second last comma for "and"
}

 

Or something that work on both cases...

[kicken]

Untested, but something like this probably would work.

 

if ($count_school_update_likes > 0) //side note: don't quote numbers.
{

$likers = array;

if ($count_school_update_liked == 1)
{
	$likers[] = 'You';
}
if ($count_school_update_likes > 1)
{
	$arr = $get_school_update_likes->result_array();
	$len=min(3, count($arr));
	for ($i=0; $i<$len; $i++)
	{
		$liker=$res[$i];
		$likers[] = '<a id="' . $liker['user_id'] . '" href="' . $liker['user_id'] . '">' . $liker['user_name'] . '</a>';
	}

	$extra = count($arr)-$len;
	if ($extra > 0)
	{
		$likers[] = '<a id="stream-updates-item-likes-view" href="#">' . $count_school_update_likes . ' others</a> ';
	}
}
$len=count($likers);
        if ($len == 1){
	$likers = $likers[0].' like this';
}
else if ($len > 1 ){
	$last=$len-1;
	$list = implode(', ', array_slice($likers, 0, $last));
	$likers = $list.', and '.end($likers).' like this';
}
}

What about, (keeping your same format):

<?php
if ($count_school_update_likes > '0')
{
$likers = '';

if ($count_school_update_liked == "1")
{
	$likers[] = 'You';
}

if ($count_school_update_likes > '1')
{
	$i = 0;

	foreach ($get_school_update_likes->result_array() as $liker)
	{
		$likers[] = '<a id="' . $liker['user_id'] . '" href="' . $liker['user_id'] . '">' . $liker['user_name'] . '</a>, ';

		$i++;

		if ($i == 2)
		{
			$count_school_update_likes = $count_school_update_likes - 3;

			if ($count_school_update_likes > "0")
			{
				$likers []= ' and <a id="stream-updates-item-likes-view" href="#">' . $count_school_update_likes . ' others</a> ';
			}

			break;
		}
	}
}
$last_likers = (isset($i) && $i > 1) ?  ' and ' . array_pop($likers) : NULL;

$likerstring = implode(', ',$likers) . $last_likers . ' like this.';

echo $likerstring;
}

 

[ibnclaudius]

jcbones, I liked that you keep the format

 

But there's some little bugs. when only the user likers, returned this:

 

and You like this.

 

Fixed with:

 

$last_likers = count($likers) > 1 ? ' and ' . array_pop($likers) : '';

 

And when more than one user liked, returned this:

 

You and Derp, like this.

[ibnclaudius]

And when more than one user liked, returned this:

 

You and Derp, like this.

 

fixed with:

 

$likers[] = '<a id="' . $liker['user_id'] . '" href="' . $liker['user_id'] . '">' . $liker['user_name'] . '</a>';

[jcbones]

I was trying to use $i, I see that didn't work, and yes, I missed that comma.  Didn't notice it until you pointed it out.

[ibnclaudius]

Thanks, all!

 

I made some changes, almost everything is correct now, the only problem is when there's only one user that liked, his name or you do not output.

 

if ($count_school_update_likes > 0)
							{
								$likers = array();

								if ($count_school_update_likes > 1)
								{
									$i = 0;

									if ($count_school_update_liked == 1)
									{
										$likers[] = 'Você';
										$i = 1;
									}

									if ($get_school_update_likes)
									{
										foreach ($get_school_update_likes->result_array() as $liker)
										{
											$likers[] = '<a id="' . $liker['user_id'] . '" href="' . $liker['user_id'] . '">' . $liker['user_name'] . '</a>';

											$i++;

											if ($i == 3)
											{
												$count_school_update_likes = $count_school_update_likes - 3;

												if ($count_school_update_likes > 0)
												{
													$likers[] = 'mais <a id="stream-updates-item-likes-view" href="#">' . $count_school_update_likes . '</a> ';
												}

												break;
											}
										}
									}
								}

								$last_liker = count($likers) > 1 ? ' e ' . array_pop($likers) . ' curtiram' : ' curtiu';

								$likers = implode(', ', $likers) . $last_liker . ' isto';

								echo $likers;
							}

[ibnclaudius]

Fixed:

if ($count_school_update_likes >= 1)

 

Thanks, all!
