Answer 1

You can use explode() to convert the string to an array and then get what you want. Like so -

$example = '1284&kec=220107&prop=220000';
$ex = explode("&kec", $example); // convert it to array where $kec is found
$value = $ex[0]; // output: 1284 // the first key will hold the value before $kec

$example2 ='11&kec=2332&prop=563454';
$ex = explode("&kec", $example2);
$value = $ex[0]; // output: 11
