PHP - Check String Is Numbers And Letters Only
Hey.
I been using a function to check if a string contains only letters which is: ctype_alpha But i would like to change it to allow numbers 0 to 9 and the letters is there a function to do that in PHP i can't find it. Similar TutorialsI'm certain this has been done a hundred times before, but I have been unable to find any information on an efficient way of doing this: I'm creating a membership system, and the password for new users needs to contains both numbers and letters. How do I go about checking this? The key is not that it contains only numbers and letters, but that it contains both. The password cannot be all letters or all numbers. Know what I mean? Cheers guys and gals. Hi Guys
I have a regex conundrum that at first I thought would be very easy but then appears to be quite hard :/
I want to match a string with a regex where the regex can only pass if it contains letters and numbers (nothing else) and it has to contain at least one of each.
I've been trying out lookaheads but just can't get it right.
Any help is appreciated.

Can I somehow mix letters with numbers to create an array with range()? e.g. I want my array for postcode ranges such as array('AB1','AB2', 'AB3', 'AB4', 'AB5', 'Ab6', 'AB7', 'AB8', 'IV5', 'IV6', 'IV7', 'IV8', 'IV9', 'IV10'); I know I can do range(1,8); but was wondering if there was something along the lines of range("AB1", "AB8"); I need users to input ONLY numbers or letters with numbers. How can i go about fixing that. Thank you. Maybe it's a Regex question, but I'm wondering how one would go about generating alphanumeric passwords that do not contain either the letters 'oh' or 'el', or the numbers 1 (one) or 0 (zero)? In other words, the p/w can contain any letters of the alphabet - apart from 'oh' and 'el' - and any digits from 2 to 9 inclusive. The p/w length is not critical - let's say 8 characters.

"cat / dog / monkey / / / / / / / /" Or this string could also have no real data in it, in which case it would look like... "/ / / / / / / / / /" QUESTION: What is the easiest/most efficient way to run a check on that string to see if there are any non-slash characters in it. In plain english, the check would say, "Are there any letters in this string, or is it only spaces and slashes?" Any ideas? Hi All, I guess there must be someway to do this with regex, but I'm not too hot on regex. What I want to do is check a text area for the presence of a phone number, and if it is there remove it. Ideally I don't want to remove all number as there might be a need for them to use a number, for example... I am 25 years old would be fine, but entering their number wouldn't be. Is there anyway of tacking this with regex, or is it going to be tricky? Many thanks, Greens85 Working through some beginner stuff and ive copied some code straight out the textbook, word for word yet it produces: Parse error: syntax error, unexpected T_ECHO, expecting ',' or ';' in C:\wamp\www\PHP Work\StringtoNumbers.php on line 11 <html> <head> <title>Strings Into Numbers</title> </head> <body> <h1>Strings Into Numbers</h1> <ul> <?php $n = "0x237a"; echo "<li>".$n."</li>" echo "<li>".($n * 3)."</li>"; $n2 = "34re5"; echo "<li>".($n2 + 2)."</li>"; $n3 = "boo"; echo "<li>".($n3 + 2)."</li>"; ?> </ul> </body> </html> %3$s displays a string of text that always begins with a number followed by a colon (from 1-25 only). 1: 2: 3: etc... Is there a way to remove the number and the colon entirely and leave the rest of the string intact? Code: [Select] function wp_rss( $url, $num_items = -1 ) { if ( $rss = fetch_rss( $url ) ) { if ( $num_items !== -1 ) { $rss->items = array_slice( $rss->items, 0, $num_items ); } //start count $i = 1; foreach ( (array) $rss->items as $item ) { printf( '<div title="%2$s"><strong>'.$i.'</strong></div><div>%3$s</div>', esc_url( $item['link'] ), esc_attr( strip_tags( $item['description'] ) ), htmlentities( $item['title'] ) ); //increment $i++; } Ashley Hey, I have an if statement that requires to check a $_POST to make sure its an integer not a string but cant remember how to do this. Anyone able to assits Thanks Hi, How can i check if a string is a multiple of 0.1 without anything being left over? like 1.6 = true, 1.46 = false How do you find out how many character within a String ?? for example: $temp = "apple"; I want to return "5" for $temp as it has 5 characters. Thanks! Hello, I'm working on an error form, and I want to check if the user inserted a number into the name field, and if so return an error. I thought this might of worked, but it doesn't: Code: [Select] if(is_int($_POST['name'])){ $arrErrors['name'] = 'Invalid name, remove numbers.'; } Many thanks How can i check if a string is URL encoded or not using PHP I want to check if a string has any of words listed in array; Code: [Select] $array=array('word1', 'word2', 'word3'); $string="This is a sentence containing word2"; Now I want to make an 'if else' to check if the string contains any of the words listed in the array. Thanks I was wondering if anyone knows a good way to check for an even number of each character in a string. For example if the string is "abbacc" then it will return true as there are two of each character. However if the string is "ababc" it will return false as there is only 1 c. Thanks for any help Hello guys, I have a form where you can select a score between 0 and 10(only integers).
I want to check if the value that I recive, is integer.
Im using this code(exemple):
$integer = intval($_POST["p1"]);
if(is_int($integer)){
echo 'INT';
} else {
echo 'NO INT';
}
My problem is that if it recive letters, the conversion converts it to 0, and it says that it is integer.
So with this method I should discard the 0.
You guys know a method to avoid that?
Thank you guys
