Voila,

j'ai un programme écrit en perl à mettre à jour ,voire réécrire et je voulais savoir si les expressions régulières de Php étaient aussi puissantes que celle de Perl ?.

En plus si ca pouvait avoir à peu près la même syntaxe ca m'arrangerait et d'ailleurs un petit prog perl2php ca serait carrément le top mais faut pas déconner, faut bien que le programmeur fasse qqch non mais ;-p

********************************************
LX. Regular Expression Functions (Perl-Compatible)
********************************************

The syntax for patterns used in these functions closely resembles Perl. The expression should be enclosed in the delimiters, a forward slash (/), for example. Any character can be used for delimiter as long as it's not alphanumeric or backslash (\). If the delimiter character has to be used in the expression itself, it needs to be escaped by backslash.

The ending delimiter may be followed by various modifiers that affect the matching. See Pattern Modifiers.

Example 1. Examples of valid patterns


/ <\/\w+> /

|(\d {3} )-\d+|Sm

/^(?i)php[34]/



Example 2. Examples of invalid patterns


/href='(.*)' - missing ending delimiter

/\w+\s*\w+/J - unknown modifier 'J'

1-\d3-\d3-\d4| - missing starting delimiter



Note: The Perl-compatible regular expression functions are available in PHP 4 and in PHP 3.0.9 and up.
