search a string

[koushikgattu]

how can i search the 1st 5 characters of a string.here is sample code

 

<?php

if($_POST['submit']) {

 

$url = "http://";

echo $url;

$array = $_POST['usersite'];

print 'You have selected these items:<ul>';

foreach($array as $item) {

 

print $item . '<br />';

echo $url.$item;

}

 

print '</ul>';

}

else {

print '<form name=' . $_SERVER['PHP_SELF'] . ' method=post>';

print '<label for=item1>Usersite : </label><input type=text name=usersite[] value="" size="50" ><br />';

print '<input type=submit name=submit value=Submit />';

}

?>

 

i want to append the "http://" to the value of the text box, if it is not entered by the user.

For that i want to search the first 7 characters from the text box value. then if "http://" is not there i will append.if its present i will directly print the value.

is there any way i could search a string like this?

 

thanks

if (substr($_POST['usersite'], 0, 7) == 'http://') {
    // code if the user has put in the http://
} else {
  // code if the user has not put in the http://
}

 

Have a look at the substr function - http://uk2.php.net/substr
