Store multiple rows from mysql database into one single variable

Question

this is really hard for me, i\'m trying to store multiple rows from my table in mysql into a single variable

---

$mysql_statementJc = \"SELECT * FROM `dog`.`ca         


        

Answer 1

You can also do it as:

$followl = array();

while($row = mysql_fetch_array($mysql_commandJc))
{ 
    $followl[] = $row['industry'];
}

$groupConcat = implode(" OR ",$followl);
echo $groupConcat;

Some Explanation:

Store values into an array $followl and than use implode() function for imploding with OR.

Side note:

Please use mysqli_* or PDO becuase mysql_* is deprecated and no more available in PHP 7.

Answer 2

Each time through the loop, add the desired value to an array. Then, after the loop, use the implode() function to create your desired output.

while($row = mysql_fetch_array($mysql_commandJc)){

    $followI = $row['industry'];

    $resultArray[] = $followI;
}

$groupConcat = implode(" OR ", $resultArray);

echo $groupConcat;

Note that you should really stop using the mysql library and instead use mysqli or PDO.

Answer 3

you want to create a concatenated string, php has the .= syntax for this:

$groupConcat='';

 while($row = mysql_fetch_array($mysql_commandJc)){
    $groupConcat .= $row['industry'] . " OR ";
}
    echo $groupConcat; //no point echoing inside the loop

sometimes a better approach is to use an array and implode()

$groupConcat=array();

 while($row = mysql_fetch_array($mysql_commandJc)){
    $groupConcat[] = $row['industry'];
}
    echo implode(' OR ',$groupConcat);
