What PHP function can find the numbers in 2c653c8e716f42b67c7aba493ce54dbc?

Question

As mentioned, thank you!

Answer 1

$content = '2c653c8e716f42b67c7aba493ce54dbc';
preg_match_all('/[0-9]/',$content, $match);
print_r( $match );

One line of code to get all the numbers

Answer 2

$a = '12ddas45fd8a9fgd6a4f08d9af';
$c ='';
for ($i = 0;$i<strlen($a);$i++){
$b=substr( $a,$i,1);
if (ord($b)<=57 && ord($b)>=48){
$c .= $b;
}
}
echo $c;

Convert the string into ascii code because the range of numbers in ascii code is 48-57. Just match it

Answer 3

<?php
$str = '200c653c8e716f42b67c7aba493ce54dbc';
//将字符串拆分成数组
$arr =str_split($str);
$str2 = '';

for($i=0;$i<count($arr);$i++){
    //判断是不是数字
    if (is_numeric($arr[$i])) {
        //拼接
        $str2.=$arr[$i];
    }
}
echo $str2;

Answer 4

You can write a piece of code to achieve it

$arr ​​=str_split('2c653c8e716f42b67c7aba493ce54dbc');

for($i=0;$i<count($arr) ;$i++){

$arr[$i]=(int)$arr[$i];

}

$int=implode(',', array_filter($arr));
