how can i strip word from a string in php - php

Question

i am displaying the top 5 results from a sql query using the following code;
<?php
$query = "SELECT location, COUNT(location) AS qty FROM ecmt_memberlist GROUP BY location ORDER BY qty DESC LIMIT 0,5";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result))
{
echo "<span class='graphValue'>x".$row['qty']."</span> " . $row['location'] . "<br />";
} ?>
this is displaying my result strings as follows:
x46 Moon 20 - Sisters of EVE Academy
x34 Moon 7 - Ammatar Fleet Assembly Plant
x28 Jita x11 Jita IV - Moon 4 - Caldari Navy Assembly Plant
x11 Jita IV - Moon 4
x9 Lonetrek III - FUUUFAGOLAS
how can i trim down the $row['location'] to show the words before the first "-" for example;
x46 Moon 20
x34 Moon 7
x28 Jita x11 Jita IV
x11 Jita IV
x9 Lonetrek III

Answer 1

Just use strstr() and print before needle, e.g.
strstr($row['location'], "-", TRUE);

Answer 2

while you could do it with php as every on else suggest, i think its better to do it with mysql:
$query = "SELECT SUBSTRING_INDEX(location,'-',1) as location, COUNT(location) AS qty FROM ecmt_memberlist GROUP BY location ORDER BY qty DESC LIMIT 0,5";

Answer 3

echo explode('-', $row['location'])[0];
OR
echo preg_replace('/\-\s.+/i', '', $row['location']);

Answer 4

$str='x46 Moon 20 - Sisters of EVE Academy';
$str2=substr($str,0,strpos($str,' -'));
echo $str2;

Answer 5

There's a couple different ways you could do this, one using explode()
$location = explode("-", $row['location']);
Then call everything before the "-" with echo $location[0]; See PHP Explode
Or you can use strstr()
$location = strstr($row['location'], '-', true);
and call it with just $location as setting the 3rd parameter to true returns everything before the first occurrence of the 2nd parameter. See PHP strstr
Or you can use split()
$location = split("-", $row['location']);
and call it using $location[0]
