Why do i get error below (preg_match) ?

[jd2007]

$string="<form method='get' action='script.php'></form>";
$regex="<form\s";
echo (preg_match($regex, $string)) ? 1 : 0;

 

i want it to show 1 if <form\s is found.

 

what i get is this:

 

Warning: preg_match() [function.preg-match]: No ending matching delimiter '>' found in C:\AppServ\www\regex1.php on line 5

you have specified that your delimiter is a less than sign. You should have done this:

 

$regex = "|<form\s|";

It probably oughta be something like this:

 

if (preg_match('/^\\<form\\s\\z/', $string)) {
echo "1";
} else {
echo "no match found";
}

$regex = "|<form\s|";

 

why do i need to use the | ?

You need to use some character to denote the start and end of a regular expression within your string.  "|" and "/" are common characters to use, but you can use almost any character.  The first charcter in the string your original code has is "<" so the error message you posted is from not being able to find the matched closing charcter.
