PHP - Check How Many Character Within A String

Hey all,

I'm looking to produce a random 10 character string like: abcABC0123 when the below method is called:

<?php

function randomize(){
   $chars = explode(' ',(range("a","z"))) . explode(' ',(range("A","Z"))) . explode(' ',(range("0","9")));
   $pass = "";
   for($i = 0; $i < $len; $i += 1){
      array_push($pass,$chars[rand(count($chars)-1)]);
   }
   return $pass;
}

var_dump(randomize(10));

?>
But the randomize method is not returning desired result. Any idea what I'm doing wrong?

Thanks for response.

I have a $string with this structure "word-word2 something-SECONDPART". I want to divide it to $string1 and $string2 by separating with the last "-".

The point is that "-" exists in the first part, and I just want to make the second string after the last "-"

I am trying to find a character in the follwing string
$string = ' Mumbai Mast Kallander - 02 - Mumbai Mast Kallander';

the character i want to find is '-' and the find how many times does it occur in the string.. can anyone help?

I have a form with some dropdownlist that get populated dynamically(depends on what the user chooses) with jquery and an xml file. In the form I have a button that takes the info and populates another form with the values of the ddl. I have coded script which populates the second form with jquery and the name of each input get dynamically added like so:

Code: [Select]
<input type="text" value="'+model+'" name="Model_'+model+'" id="'+model+'" readonly size="'+model.length+'" />
<input type="text" value="'+model+'" name="Model'+model+'" id="'+model+'" readonly size="'+model.length+'" />>
<input type="text" value="'+color+'" name="Color'+color+'" id="'+color+'" readonly size="'+color.length+'" />
<input type="text" value="'+part+'" name="Part'+part+'" id="'+part+'" readonly size="'+part.length+'" />
<input type="text" value="$'+price+'" name="Price'+price+'" id="'+price+'" readonly size="'+price.length+'" />
<input type="text" value="'+qty+'" name="Quantity'+qty+'" id="'+qty+'" readonly size="'+qty.length+'" />
<input type="text" value="'+total+'" name="Total'+total+'" id="'+total+'" readonly size="'+total.length+'" />

What I want to do is grab the name of the element and remove the underscore and everything else form rileft to right so I am left with just the word before the underscore. I tried using substr($key,0,-28) but that wont work since everything after the underscore will have a different length. I was wondering if there is a way i can keep everything before the underscore and remove the underscore and everything after that.
Thanks in advance for any input I get.

I have a kind of search and react on my site. The user can search for a number in a column as below

$search = mysqli_real_escape_string($link, $_POST["query"]);

$query = "SELECT * FROM $table[$i] WHERE oemnr LIKE '".$search."%' ORDER BY model";

 

The code works fine but I want to expand the function to get match for other numbers also. The oemnr column today can be 12345 which shows up if the user type 12.... 

I want to expand the oemnr column as

12345/03124/34713, numbers separated with / or another character.

If the user type 03... or 34... I want to find and show 12345 because it is on the same row and corresponds to the numbers on the same row. Is it possible to do in mysql? In php that kind of operation can be done with the explode function but I don't know how to use with mysql.

Hi all, i've got a string ($currentcatid) which contains one number which changes dependant on which page the visitor is on.. ie  it may be perhaps "23" or "17" .

I need to do a check against this string to see if it contains any of the following values .. 31,32, 1, 24 . I cant remember how i did it before but i think it was with pipes..

something along the lines of
if ($currentcatid =="31"||"32"||"1"||"24") { action }

can anyone help?

Thanks

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 

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

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.

I want to allow Alphabetical strings, Numeric strings, and Alphanumeric strings. For example "Bob", "1234", "bob1234" are all valid.

I want to check if the string has invalid characters, return true if it does (or false, which ever method works).

How can I do it?
