Anyone know of a function that will count only the number of letters in a string and only the number of digits in a string?

[etech]

$variable = strlen("TestString"); 

strlen will return the number of characters in the string

<?php

  $str = "00jkjdj0";
  
  $char_count = 0;
  $num_count = 0;
  
  $u_bound = strlen( $str ) - 1;
  
  for( $i = 0 ; $i <= $u_bound ; $i++ ) {
  
    if( is_numeric( $str{ $i } ) ) { $char_count++; } else { $num_count++; }
  
  }
  
  echo $char_count;
  echo $num_count;
  
?>

Sorry. I mixed up my variabless in the following line (unless you want to use $char_count as the number count variable and $num_count as the character count variable ) ...

if( is_numeric( $str{ $i } ) ) { $char_count++; } else { $num_count++; } 

It should read...

if( is_numeric( $str{ $i } ) ) { $num_count++; } else { $char_count++; } 

Full code:

  $str = "00jkjdj0";
  
  $char_count = 0;
  $num_count = 0;
  
  $u_bound = strlen( $str ) - 1;
  
  for( $i = 0 ; $i <= $u_bound ; $i++ ) {
  
    if( is_numeric( $str{ $i } ) ) { $num_count++; } else { $char_count++; }
  
  }
  
  echo $char_count;
  echo $num_count;

Its cheaper to outsource the job to eager young pakistani counting experts
