Search for a file with Current Date
Hi,
How can we search for a file with current date(sysdate).
Actually i want the file name from a directory which was created today(current date).
For example i have a dir /home/arch and i have files with name aglito03axyz.datetimestamp in this directory, but all these files were created on different dates. suppose we have 3 files :
dba May 18 00:06 aglito03axyz.20090518000506.arc
dba May 19 00:07 aglito03axyz.20090519000511.arc
dba May 20 00:07 aglito03axyz.20090520000506.arc
from the above we have 3 files with name aglito03axyz.datetimestamp and were created on different days, suppose i want the file created today(May 20th 2009) then i should get the file name as aglito03axyz.20090520000506.arc.
How can this be achieved.
Thanks
Sandeep

cairo_arc
CAIRO_ARC(3) 1 CAIRO_ARC(3)
CairoContext::arc - Adds a circular arc
Object oriented style (method):
SYNOPSIS
public void CairoContext::arc (float $x, float $y, float $radius, float $angle1, float $angle2)
DESCRIPTION
Procedural style:
void cairo_arc (CairoContext $context, float $x, float $y, float $radius, float $angle1, float $angle2)
Adds a circular arc of the given radius to the current path. The arc is centered at ($x, $y), begins at $angle1 and proceeds in the direc-
tion of increasing angles to end at $angle2. If $angle2 is less than $angle1 it will be progressively increased by 2*M_PI until it is
greater than $angle1. If there is a current point, an initial line segment will be added to the path to connect the current point to the
beginning of the arc. If this initial line is undesired, it can be avoided by calling CairoContext::newSubPath or procedural
cairo_new_sub_path(3) before calling CairoContext::arc or cairo_arc(3). Angles are measured in radians. An angle of 0.0 is in the direction
of the positive X axis (in user space). An angle of M_PI/2.0 radians (90 degrees) is in the direction of the positive Y axis (in user
space). Angles increase in the direction from the positive X axis toward the positive Y axis. So with the default transformation matrix,
angles increase in a clockwise direction. (To convert from degrees to radians, use degrees * (M_PI / 180.).) This function gives the arc in
the direction of increasing angles; see CairoContext::arcNegative or cairo_arc_negative(3) to get the arc in the direction of decreasing
angles.
PARAMETERS
o $context
- A valid CairoContext object
o $x
- x position
o $y
- y position
o $radius
- Radius of the arc
o $angle1
- start angle
o $angle2
- end angle
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
Object oriented style
<?php
$s = new CairoImageSurface(CairoFormat::ARGB32, 100, 100);
$c = new CairoContext($s);
$c->setSourceRgb(0, 0, 0);
$c->paint();
$c->setLineWidth(1);
$c->setSourceRgb(1, 1, 1);
for ($r = 50; $r > 0; $r -= 10) {
$c->arc(50, 50, $r, 0, 2 * M_PI);
$c->stroke();
$c->fill();
}
$s->writeToPng(dirname(__FILE__) . '/CairoContext__arc.png');
?>
Example #2
Procedural style
<?php
$s = cairo_image_surface_create(CAIRO_SURFACE_TYPE_IMAGE, 100, 100);
$c = cairo_create($s);
cairo_set_source_rgb($c, 0, 0, 0);
cairo_paint($c);
cairo_set_source_rgb($c, 1, 1, 1);
cairo_set_line_width($c, 1);
for ($r = 50; $r > 0; $r -= 10) {
cairo_arc($c, 50, 50, $r, 0, 2 * M_PI);
cairo_stroke($c);
cairo_fill($c);
}
cairo_surface_write_to_png($s, dirname(__FILE__) . '/cairo_arc.png');
?>
