Access specific row in mysql recordset - php

Question

I have a database table with options that looks like this
I do a SELECT * FROM options and load all records into a recordset.
How do I then access just the optionValue of optionName = SMSactive
[EDIT]
Yes, I could do SELECT * FROM options WHERE optionName ='SMSactive' - I know that.
But as I said, since I have a recordset with a bunch of rows in it (from the SELECT), I want to pull a specific row where optionName = SMSactive
[EDIT]
If you are using PHP >= 5.5 you can use array_column() http://php.net/array_column
But if not, the question has already been asked and answered here PHP multidimensional array search by value

Answer 1

To access to all records with optionName = SMSactive the SQL should be:
SELECT * FROM `TableName` WHERE `optionName` = 'SMSactive'
if your array result from the query is something like this:
$array = array(
0 => array(
'optionName' => 'lala0',
'optionDescription' => 'lala01',
'optionValue' => 'lala03',
),
1 => array(
'optionName' => 'lala1',
'optionDescription' => 'ala2',
'optionValue' => 'SMSactive',
)
);
You can grab who has 'optionValue' => 'SMSactive', by this way
foreach ($array as $key) {
if ($key['optionValue'] == 'SMSactive') {
$filtered[]=$key;
}
}
echo '<pre>';
print_r($filtered);
echo '</pre>';
Side Note: If the array is very large you have to be careful with the memory...it's advisable just get from the db what you are using in the moment...IMO
