I'd like to count how many numbers and letters are in the variable using PHP. Below if my code:
$lot_num = strtoupper('e1,1,2,3,4,5,7,8,9,10,11,12,13,14,15,16,17,18,e18');
echo 'END UNIT: '.substr_count($lot_num, 'E').'<br />';
the code will count how many letter E are there in my lot_num variable but i would also like to count how many numbers are in the variable. Supposed, E1 and E18 should not be included when counting numbers.
I hope you can help me guys.
Try this: explode on , to get array that can be counted.
$lot_num = strtoupper('e1,1,2,3,4,5,7,8,9,10,11,12,13,14,15,16,17,18,e18');
$ecount = substr_count($lot_num, 'E');
$totcount = count(explode(",", $lot_num));
echo 'END UNIT: '.$ecount;
Echo "\ntotal count: ". $totcount;
Echo "\nother count: ". Intval($totcount-$ecount);
No loops and no regex makes it a simple and quick solution.
You could always turn it into an array and use a loop:
$lot_num = explode(',',strtoupper('e1,1,2,3,4,5,7,8,9,10,11,12,13,14,15,16,17,18,e18');
$count = 0;
for ($i=0;$i<count($lot_num);$i++) {
if (is_int($lot_num[$i])) { //detects all numbers
$count++;
}
}
echo $count;
$lot_num = strtoupper('e1,1,2,3,4,5,7,8,9,10,11,12,13,14,15,16,17,18,e18');
$array = explode(',', $lot_num);
$data=array();
foreach($array as $k=>$val){
if(is_numeric($val )){
$data['number'][] = $val;
}else{
$data['string'][] = $val;
}
}
echo count($data['number']);
echo count($data['string']);
you can use is_numeric() and
if (!preg_match("/^[a-zA-Z]$/", $param)) {
// throw an Exception...
}
inside a loop
Id use preg_match
preg_match('/\b([0-9]+)\b/', $lot_num, $matches );
And matches would be like this.
$mathes[1][1,2,3,4,5,7,8,9,10,11,12,13,14,15,16,17,18]
So you would
$lot_num = strtoupper('e1,1,2,3,4,5,7,8,9,10,11,12,13,14,15,16,17,18,e18');
$total = 0;
if( preg_match('/\b([0-9]+)\b/', $lot_num, $matches )){
$total = count( $mathes[1] );
}

1,first u have to seperate the string and stored into array
2,then u can easily count the value of integers
<?php
$lot_num =explode(',',strtoupper('e1,1,2,3,4,5,7,8,9,10,11,12,13,14,15,16,17,18,e18'));//seperate string by ","
$arr_count=count($lot_num);
for($i=0;$i<$arr_count;$i++)
{
$get_num[]=$lot_num[$i];//saving seperated string value into array
}
$count=0;
for($j=0;$j<count($get_num);$j++)
{
if(is_numeric($get_num[$j]))//chect whether the value is integer or not
{
$count++;
}
}
echo $count;
preg_match('/\b([0-9]+)\b/', $lot_num, $matches )
