PHP - preg_match?

Question
I'm not very good with expressions... I've looked at some online tutorials, but I'm still not getting it. Basically, I'm trying to return TRUE
if a string is formatted like this:
4 digits + space + 2 digits and convert it to a date.
So, the string will look like: 2010 02
, and I'm trying to output February, 2010
.
I'm trying to use preg_match
, but I keep getting
{ is not a modifier...
EDIT
Per the first 2 responses, I changed it, but am getting a fatal error on the first and the same unknown modifier error on the second:
if(preg_match('/([0-9{4}]) ([0-9]{2})/iU',$path_part)) {
$path_title = date("F, Y",strtotime(str_replace(" ","-", $path_title)));
}
Also, just tried the more in-depth version in the first response, and while the error goes away, it doesn't change the output...
$path_part = '2010 02';
if(preg_match('/^(\d{4}) (\d{2})$/',$path_part,$matches)) {
$path_title = $mon[(int)$matches[2]] . " " . $matches[1]; // prints Feb 2010
}
Solution
I'm trying to return TRUE if a string is formatted like this: 4 digits + space + 2 digits
return preg_match(/^\d{4} \d{2}$/,$input);
To convert to date you can try something like:
$mon = array('','Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec');
$date_str = "2010 02";
if(preg_match('/^(\d{4}) (\d{2})$/',$date_str,$matches))
{
print $mon[(int)$matches[2]] . " " . $matches[1]; // prints Feb 2010
}
OTHER TIPS
Try this one...
preg_match('/([0-9{4}]) ([0-9]{2})/iU', $input);
Without having any detail as to your actual code, the following should work:
<?php
$str = '2010 02';
$months = array('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December');
if(preg_match('/([0-9]{4}) ([0-9]{2})/', $str, $match) == 1){
$year = $match[1];
$month = (int) $match[2];
echo $months[$month - 1] . ', ' . $year;
}else{
//Error...
}
?>
$in = "2010 02";
if(preg_match('/([0-9]{4}) ([0-9]{2})/i', $in, $matches)) {
echo date("F Y", strtotime($matches[2] . "/1/" . $matches[1]));
}
You can also use T-Regx library
$string = '2010 02';
pattern('\d{4} \d{2}')->match($string)->first(function (Match $match)
{
$year = $match->group(1);
$month = $match->group(2);
});
