Hello to all,
I'm trying to separate the string "str" using a regex within match function.

replace 22 with MJS, 23 with UYT, 24 with WER and 25 with PIL.

So far no problem.

Hello,
I'm looking at simplfying a function that flattens an array, it uses recursion and filters objects by type but this seems to be a waste of resources to me at least, using conditionals like this seems like a bad idea.
The array can be a generic type, int, string, float but not some... (2 Replies)

EXAMPLES
Example #1
A ctype_digit(3) example
<?php
$strings = array('1820.20', '10002', 'wsl!12');
foreach ($strings as $testcase) {
if (ctype_digit($testcase)) {
echo "The string $testcase consists of all digits.
";
} else {
echo "The string $testcase does not consist of all digits.
";
}
}
?>
The above example will output:
The string 1820.20 does not consist of all digits.
The string 10002 consists of all digits.
The string wsl!12 does not consist of all digits.
Example #2
A ctype_digit(3) example comparing strings with integers
<?php
$numeric_string = '42';
$integer = 42;
ctype_digit($numeric_string); // true
ctype_digit($integer); // false (ASCII 42 is the * character)
is_numeric($numeric_string); // true
is_numeric($integer); // true
?>
NOTES
Note
This function expects a string to be useful, so for example passing in an integer may not return the expected result. However, also
note that HTML forms will result in numeric strings and not integers. See also the types section of the manual.
Note
If an integer between -128 and 255 inclusive is provided, it is interpreted as the ASCII value of a single character (negative val-
ues have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string contain-
ing the decimal digits of the integer.
