arrays - how to use php to check if a variable contains a group of characters

View Original

i have a variable and i want to use php to check if it contains a group of characters i would like the code to be like this

$groupofcharacters = ["$","#","*","("];
if($variable contains any of the letters in $groupofcharacters){
//do something}

i know that this will need the use of strpos() function but how can i use the strpos function to check if a variable contains a group of characters without me having to create a strpos() function for all the characters that i want to check for.

please if you don't understand you can tell me in the comments

Solution:

Best way to solve your issue is by using RegEx. Try this:

<?php
$variable = 'Any string containing $*(#';
$sPattern = '/[$#*(]/';

if (preg_match($sPattern, $variable)) {
    // Do something
}

Solution:

You can use to achieve this. The doc says:

strpbrk ??� Search a string for any of a set of characters

Returns a string starting from the character found, or FALSE if it is not found.

Snippet:

<?php

if(strpbrk($variable,"$#*(") !== false){
   // your logic goes here
}

Answer

Solution:

check if it has any char. Using strpos First you need to combine the array as string after check ot if there's one of them in the

$groupofcharacters = ["$","#","*","("];
$strs = implode("", $groupofcharacters);

foreach(str_split($variable) as $s) {
   
   if (strpos($s, $strs)) {
      echo "it contains "; continue;
   }
}
