Someone will probably come up with a better regex but try:
<?php
$foo = array(
"20;",
"419;",
"19;20;21;",
"20;19;21;",
"21;20;19;",
"19;",
"194;",
"18;30;",
"17;20;25;",
"16;26;",
"16;17;20;21;22;34"
);
foreach ($foo as $bar) {
if (preg_match("/^19;|;19;/", $bar)) {
echo $bar."<br>\n";
}
}
?>
This matches:
19;20;21;
20;19;21;
21;20;19;
19;
