Takes in two strings. Returns a number. $strcasecmp is positive if the first string is “greater than” the second and negative if the first string is “less than” the second. $strcasecmp returns 0 if the strings are identical.
注解
$strcasecmp may not make sense when applied to glyphs outside the Roman alphabet.
$strcasecmp internally capitalizes strings before comparing them to provide a case-insensitive comparison. Use $cmp for a case sensitive comparison.
