preg_match() gives one match.preg_match_all() returns all matches.preg_split() returns all splits.
How can I split only on the first match?
Example:
preg_split("~\n~", $string);
This is what I want:
array(
0 => 'first piece',
1 => 'the rest of the string
without any further splits'
)

Use the String. split() method with array destructuring to split a string only on the first occurrence of a character, e.g. const [first, ... rest] = str. split('-'); .
Use the str. split() method with maxsplit set to 1 to split a string on the first occurrence, e.g. my_str. split('-', 1) . The split() method only performs a single split when the maxsplit argument is set to 1 .
Using the split() Method For example, if we put the limit as n (n >0), it means that the pattern will be applied at most n-1 times. Here, we'll be using space (” “) as a regular expression to split the String on the first occurrence of space.
Split method. String. Split provides a handful of overloads to help you break up a string into a group of substrings based on one or more delimiting characters that you specify.
Simply set $limit to 2 for 2 parts of the array. Thanks to @BenJames for mentioning:
preg_split("~\n~", $string, 2);
I tested and it works fine.
The limit argument:
If specified, then only substrings up to limit are returned with the rest of the string being placed in the last substring. A limit of -1, 0 or null means "no limit" and, as is standard across PHP, you can use null to skip to the flags parameter.
