Verify length of each string of an array - php

Question

I want to make a verification that if one of these strings has a length greater than 40 echo "this array contains a string with a length greater than 40". So in this case the index [11] contains a string length that is greater than 40. How can I do that?
array(5) {
[0]=>
string(19) "PEDRO MOACIR LANDIM"
[1]=>
string(19) "ADIR JOAO GASTALDON"
[2]=>
string(18) "ABEL PEDRO MARQUES"
[10]=>
string(28) "ADRIANO CESAR GARCIA JOAQUIM"
[11]=>
string(44) "AUTO VIAÇÃO CATARINENSE LTDA - FLORIANÓPOLIS"
}

Answer 1

foreach ($array as $key => $value) {
if(mb_strlen($value) > 40){
echo "this array contain a string wich lenght is greater than 40: ".$key;
}
}

Answer 2

Since only one of the strings is needed to be detected if it's greater than 40, it's better to break the loop once a number greater than 40 is encountered. This can reduce the number of iterations executed by your for loop if ever the number isn't located at the last index of your array.
foreach ($array as $arr) {
if(mb_strlen($arr) > 40){
echo "this array contain a string wich length is greater than 40";
break;
}
}

Answer 3

You can do this:
<?php
$myStrings = array(
0 => "PEDRO MOACIR LANDIM",
1 => "ADIR JOAO GASTALDON",
2 => "ABEL PEDRO MARQUES",
10 => "ADRIANO CESAR GARCIA JOAQUIM",
11 => "AUTO VIAÇÃO CATARINENSE LTDA - FLORIANÓPOLIS"
);
foreach($myStrings as $key => $string){
//Get length of string
$len = strlen( $string );
if( $len > 40 ){
echo
'this array contain a string wich length is greater than 40. Array key:
' .$key. ' | array string: ' .$string;
break;
}
}
?>
