CTYPE_ALPHA(3) 1 CTYPE_ALPHA(3)ctype_alpha - Check for alphabetic character(s)SYNOPSIS
bool ctype_alpha (string $text)
DESCRIPTION
Checks if all of the characters in the provided string, $text, are alphabetic. In the standard C locale letters are just [A-Za-z] and
ctype_alpha(3) is equivalent to (ctype_upper($text) || ctype_lower($text)) if $text is just a single character, but other languages have
letters that are considered neither upper nor lower case.
PARAMETERS
o $text
- The tested string.
RETURN VALUES
Returns TRUE if every character in $text is a letter from the current locale, FALSE otherwise.
EXAMPLES
Example #1
A ctype_alpha(3) example (using the default locale)
<?php
$strings = array('KjgWZC', 'arf12');
foreach ($strings as $testcase) {
if (ctype_alpha($testcase)) {
echo "The string $testcase consists of all letters.
";
} else {
echo "The string $testcase does not consist of all letters.
";
}
}
?>
The above example will output:
The string KjgWZC consists of all letters.
The string arf12 does not consist of all letters.
NOTES
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.

Hi,
What is installation package and how to create it?
When we run:

installp package1
or
in Linux
rpm -ivh mypackage
What is package1 or mypackage in the abov examples and how to create them and deploy them?
I hope my question is clear enough.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
