The test utility's
primary (which is an extension to the standards) performs a string comparison; the
primary (which is required by the standards) performs a numeric comparison.
As an example:
prints string comparison but:
prints numeric comparison.
And, you got the syntax error because you need a space between the if and the [; i.e., if [ ... instead of if[ ...

substr_compare
SUBSTR_COMPARE(3) 1 SUBSTR_COMPARE(3)substr_compare - Binary safe comparison of two strings from an offset, up to length charactersSYNOPSIS
int substr_compare (string $main_str, string $str, int $offset, [int $length], [bool $case_insensitivity = false])
DESCRIPTION substr_compare(3) compares $main_str from position $offset with $str up to $length characters.
PARAMETERS
o $main_str
- The main string being compared.
o $str
- The secondary string being compared.
o $offset
- The start position for the comparison. If negative, it starts counting from the end of the string.
o $length
- The length of the comparison. The default value is the largest of the length of the $str compared to the length of $main_str
less the $offset.
o $case_insensitivity
- If $case_insensitivity is TRUE, comparison is case insensitive.
RETURN VALUES
Returns < 0 if $main_str from position $offset is less than $str, > 0 if it is greater than $str, and 0 if they are equal. If $offset is
equal to or greater than the length of $main_str, or the $length is set and is less than 1 (prior to PHP 5.6), substr_compare(3) prints a
warning and returns FALSE.
